If you put gorilla tape on the back of your target it holds the paper together really well and you can get a better idea of the group size without the tearing of the paper.
I have the EC tuner brake on my 6.5 RPR Creedmore, first thing I noticed, the muzzle jump was gone, and within a few minutes I was shooting 1 hole groups, so I ordered a 2nd EC tuner for my 300 PRC RPR,
@@dirklabuschagne473 I have shot it on my RPR, which comes with a huge brake from factory, the EC tuner works great to tune, with just slightly more recoil
Only thing missing for me is. They did not show, does that setting repeatable. One group doesn't seal the deal! They speak of it at the end. Is there a follow up video.
I'm just glad Eric's dedication and hard work is finally getting shown to more people. This whole system has come from his many year's of precision shooting into his own workshop that was specifically built to build something like this.ThankQ.TkEZ>UK
I have two of these and I love it when the rifle goes into tune. It doesn't make a sound when firing. When it's out of tune it's like a tuning fork going off every shot. This brake basically takes out the need to move the bullet in and out to find the seating depth the rifle likes. You can make it even smaller a group by adding that in, but really 0.2 is fine for PRS. I have had no issues with repeatability. Erik stands by his product and at F-Class and PRS matches I see a ton of EC tuners, because he makes other styles and calibers.
I have Erik's EC TUNER on my 6.5X47 Lapua and cut my group size in half down to .31" shooting 140 Berger Hybrid. Then put it on my .224 Valkyre and again my group size was reduced to .30" shooting 80.5 Berger fullbore target. Reminded me of my old Browning BOSS tuner from many years ago. Thank you Erik!
I have it (in polished stainless and would rather have black) and I ran a very comprehensive test. There is no doubt that it works exactly as advertised and designed. My range was from around 3/4 moa to inside 1/4 going through the settings. My sweet spot is at "4" and it's good still at just past 3 and just short of 5.
My first example of a barrel tuner was a model 70 Winchester with a boss system, once adjusted it was amazing how much effect it had on group size with factory ammunition
Ding ding ding ding! We have a winner. I have older Winchester and Browning rifles with the BOSS installed, and they pretty much eliminate so-called "ammo pickiness". It doesn't work with everything, but the BOSS will help make your rifle "like" a much larger range of loads, and will produce groups you'll love.
I put this ec tuner brake on a rifle that shoots amazing. I just wanted to c if I could get rid of an occasional flyer when using a bullet that actually needed a faster twist barrel. After adjusting the tuner I have completely eliminated the flyer issue. I’m very impressed with this product!!! I’ve put off getting a barrel with a faster twist.
I bought a EC Tuner for my Remington 700-7mm REM Mag elk hunting rifle. My results were definitely similar to yours. My three shot groups went from .815 @ 100 yds to .279” @ 100 yds. I did have a setting where my groups opened up to over 1” (1.40”) then back to my best grouping. As a side note I was using IMR-4831 powder and Nosler 160 gr Accubond bullets.
Gavin i have the original Ec Tuner on my custom 6xc just like everybody i was a little skeptical to but had the gunsmith install it on a Bartlien heavy varmint on a Defiant action. All i can say is this gun is a tack drive went through some test and settled on number eight, shot a five shot group at 100 yards just under 1/4 inch group, did this test a couple more times same results, it’s made me a believer.
WORTH IT'S WEIGHT IN GOLD! I threw it on did some load work up found a good load 144 Berger and H4350 SD of 2.4 on my magneto speed. Loaded up 30 rounds took the magneto speed off and started fine tuning.3 shot groups starting at 1 to 8. Found it grouped well at 4 and 5. So I split the difference and wow! 5 shot group @.18 inches and .22 inches. Absolutely amazing product.
I started reloading this year and I have an EC tuner break on my 300 wm. The best I could get my reloads was a half inch group but by using the EC tuner I’m now shooting 1/4 inch groups. With factory ammo my gun will shoot 1 inch groups but the EC tuner will help me get them under a 1/2 inch groups. My rifle is a Christensen arms ridgeline. I have also changed the stock. With the stock change and the tuner break it kicks less than my 7mm-08. I enjoy watching your videos because you are very informative. Please keep up the good work.
I bought one, for my 300 BO with a 16"BBL. on a Unitau Precision Upper. it hates boat tail bullets. With 168 gr A Max. Just the break cut the groups in half with no adjustment.
Statistics of distribution do not favor barrel tuners. Two 30 shot groups, one without tuner and 1 with the tuner in a “node” could tell us definitively if the tuner works, but I’ve never seen this done.
Bought one of these for my .338LM. Worked amazing, love it. Loved it so much I just ordered another one for my 6.5CM. And I can't wait to see how much it changes things on an already great shooting rifle.
Another killer aspect of tuner is if you run data in temp changes and record it, you can tune load in colder/warmer weather. I run a 6.5 Lapua for PRS and it works. Without having 2 different loads.
Bought an EC tunner for my 6.5 cm. My biggest surprise was reduction in recoil. I was surprised it has less recoil than my suppressor ( Gemtech 300 win mag). My last 3 shot group was .218
I'm curious about conistancy. Maybe firing 3 groups per setting then averaging them. That way you don't get one crazy good group skewing your conclusions.
Just bought an EC tuner brake. I’m having it installed now. Can’t wait to try it out. My best 5 shot group from my .308 is .478 with Federal premium 168 BTHP. This video has me really excited to see how much tighter my groups can get.
@@BLUELEADER78 I did a lot of shooting and testing this month. The EC Tuner brake did a fantastic job. I did most of my testing with Federal premium 175 bthp ammo. I did some testing with 168 and was able to tighten the groups down to .365 for a five-shot group. I ran out of 168 and switched to 175 BTHP. Before the EC brake my rifle would shoot the 175 in the 3/4 moa range very consistently. I started firing 2 shot groups at 0 going in increments of 2. At setting 2 they were touching but I continued on all the way back to 0 being 10. Setting 2 and 8 were both touching. 8 was very slightly tighter. I dropped back to 7 and went in half step adjustments. At 7 it had opened up to about 1/2", 7.5 was about the same, skipped 8, 8.5 was almost 1 hole but I could see it was 2 shots. Setting 9 was 1 hole, I couldn't tell through my spotting scope that 2 shots were there. I sent 3 more making it a 5 shot group. Subtracting the .308 for the bullet diameter the group measured .210. Thats a .518 hole with a .308! Wow, factory Remington 700 PSS .308 26" 1:12 twist with a Timney trigger and an EC Tuner brake is shooting factory ammo sub 1/4 moa !! Will it do it every day, probably not but that remains to be seen. I can say that I am a 100 percent believer in the EC Tuner brake.
I have the 30cal brake i swap on 6cm 6.5cm and 6.5-300bee. Set to original settings and it stays true. Takes half of the work out of load development. Erik makes an amazing product.
I was wondering if the 30 cal brake would be effective on lower caliber rounds, that is how well it would work to reduce recoil and tune .280 and .270 cal rifles. Sounds like it works on your rifles.
I picked one up a while ago and it works wonders on my rifles! It saves me a lot of time and money so I don't have to play around with bullet seating depth especially when getting components are hit and miss.
Yes, I use the EC tuner with a 6.5 PRC currently worthing with a load. The rifle is a new MPA with factory match bullets it shot well 1/2 with the turner .119.
Easiest thing to do would be to have a tuner for each rifle. But, I like the repeatability idea for those on a budget and want, or are limited to, that capability. I'm a fan of Erik and have learned a lot from his channel.
For those weary of the tuner brake; buy one and install it as if it were a standard brake. Develop a load conventionally with a powder and seating depth node that shoots well. When you go to a match and your groups start opening up because of throat erosion or change in temperature/pressure, you can adjust your tuner on the fly as a backup. I think this thing can cut your load development time in half. It would be so nice to find a powder charge with low sd and then you could essentially finish your load development in 1 day at the range as opposed to making a bunch of trips back to your reloading bench
YES! Definitely test taking the EC Tuner off of the rifle, messing with the setting and then remount and set back to desired setting. I'd love to see that tested. I'm an Eric Cortina fan because he clears the muddy water stirred up for us who have less knowledge, he backs it up with proof
I inherited a browning ab2 .270 with the boss break on it. After shooting a 3/8” group 4 times, i really wanted to get a boss break for my other rifles, but found out that browning discontinued them. I am very happy to see the EC tuners are basically the same thing and work well. My savage 22-250 is about to be stupid accurate lol.

@@travisweldmaster7815 my uncle in law is an avid hand loader and long range shooter.

I shoot 165 ablr’s out of my 30-06, and it is a mortar as well, but its strictly a hunting rifle, so I don’t shoot it far enough to really care.

Years ago I HAD 3 Winchester Boss System rifles, 243, 300 Win, 7mm mag. Each shoot 1/3 MOA. Sold them along the way..... About time someone came out with a Boss style system. I'll buy a few dozen.
One test I would like to see is to take the tuner out several rotations and see what happens if you go from zero to say 30. Is there more than one node that can be found and at what distance might that be?
I have a 6 ARC 22” bbl in a gas gun, would be very interested in getting a break, like the one you guys tested. My bbl has a 5/8 thread like the 6.5 Grendel has also.
Would love to see you do the tuner adjustment as shown. Then shoot a 20 shot group with the best and worst settings. Also, as others have said step back through the adjustment a 2nd time and see if you land on the same settings for best and worst groups.
I just got back from the range. I have the EC..2 tuner break, and it's amazing. I'm getting ready for hunting . I loaded with no load development. I used 40 guns of Varget, under a Berger 175 grn vld hunter. At setting 8 I got.25 inch group at 100. I tried 7 and it opened up to 3/8". I went to 8+ and it shrunk the group to 0.029 ,3 shot group. No load development. I'm good for in the bush where my longest shot will be just over 200 m over a pond.
Use the tuner brake on my prs 22 br. 95 gr smk, h4350. Last group on paper was measured at .281-.224=.057 for 5 shots. Consistently shoots from .2-.0. Best shooting equipment I've bought!
This sounds like the product I may need. I had a load that consistently shot .5” inch groups at 100 yards with single digit ES/SD. Shot a 4” six shot group at 995 yards with that load. Then I ran out of powder and switched to a different lot of the same powder. For reasons I’m still scratching my head trying to figure out why the groups went to crap. I would have three touching and two fliers high and low. However, the velocity node stay the same with single digit ES/SD at the same charge weight. The velocity did drop approximately 50 fps though. I also developed a load for a couple 308 rifles that have BDC reticles, is gas operated and the other is bolt action. The load I’ve developed runs identical ES/SD in both rifle, low teen ES and single digit SD, and the ballistics match the BDC reticle. The bolt gun shoots a consistent .5” five touching group at 100 yards, but the gas gun shoots .8”. I imagine this brake may shrink those gas gun groups down some more.
Yeah,I put a brake on a 25 WSSM AR.IT went from 1/2 “ groups to 1 1/2” or worse.Took the brake off,tightened up.So I have a EC TUNER brake on order .Hopefully it will not let me down
I've had a stainless Winchester model 70 in 30-06 for over 25 years. It came with the BOSS system...and was apparently way ahead of it's time. It is the same principle as this - a brake with a tuner. It's a shame it was discontinued. I dialed it in for factory 150gr loads when I first got it and it shot 1/2" groups...and it has shot them continuously since then.
I tuned mine for 168s and has been fantastic for years as well. No need to buy another rifle since. Have about 800 rnds through it now, so there's plenty of life left in it. My buddies that shoot it can't believe that the '06 could be that accurate. It can.
Thanks for a very interesting and practical experiment. Currently there is not a temperamental rifle in my safe, however if I do have issues the EC Tuner will be part of my solution.
I have his EC Tuner Break in 308 and 6.5. shot a 3 shot 308 group tuned to #7 on the break.... Hole diameter was .398 on the target. Still working load data for the 6.5. Love the breaks
I used the 30 caliber EC Tuner Brake on my 700 Remington CDL 7mm Remington Magnum and the difference was worth every penny spent. Results on my hand loads- three shot groups starting 0.78” we shrunk to 0.19” which essentially was one button hole. Never look back!
When taking it off and putting it back on i would try and use a crows foot on a torque wrench to make sure the tightness to the muzzle is the same to remove another value from testing.
I may have missed it, but it would be nice to hear if the brake portion of the tuner brake is effective also. I am on the fence now and don't like the brake on my current setup. Keep the great videos coming.
So is it safe to say that using a magneto speed could alter your guns groups and make a good load look bad? My custom 270 stacks rounds in a 1/4 MOA group all day long but last time I shot it with my magneto speed the group's were about 3/4 MOA and I was confused because it was the same load. Now I'm thinking the magneto speed effected my harmonics. I guess from now on during load development I'll only use the magneto speed after I find a load that groups well.
Typically we start with the bullet we want to shoot then powder and powder charge. The tuner brake would come once you have hit the variable you are “aiming” for, low es, sd, or velocity. Then tune the brake.
Yeah basically your method would be run a ladder and pick the charge weight that has the smallest standard deviation on velocity. Then load up a bunch of that load. And take the ones you just loaded that are all the same load with your best standard deviation of velocity, and shoot a fire you shot group turn out the turner. Shoot another group. Turn out the tuner. And so on. By the time you've done say 50 rounds there you should have found a couple of nodes that are fairly accurate. You know I don't have to compromise between a harmonic node and a consistent velocity node you can choose both. You adjust your powder to be the consistent velocity and you adjust your barrel to be the consistent harmonic.
@@GunFunZS Thanks. I've been working up a load for my hunting rifle using Barnes 175gr .308 LRX with Superformance powder with CCI250 primer and Winchester brass. I've used Dan Newberry's OCW method and I tried the Saterlee 10-shot ladder test and they both gave me 58.0 gr of Superformance as the sweet spot. I then played with the seating depth, but my riflescope started acting funny and it turned out to be defective. I finally got a new/used Vortex Viper HS-T 4-16x44mm scope 2 days ago so I hope to get back to the range soon and finish the load development. Cheers!
@@onelegwest I'm willing to bet money on two things. 1 you were probably a much better shot than me. 2 The defect of that rifle you rejected was probably more than sufficiently accurate for the hunting you're actually going to do with it. And the third thing that I won't bet on but do suspect is that you will end up with a very accurate load by the time you are done.
We have the BOSS on a Model 70 in .270 and another on an A-Bolt Eclipse Varmint in .308, I don't know why they stopped producing them as they really work well.
I'm curious how ambient temperature would affect tuner results. I suppose if powder burn was exactly the same at any temperature, there would be no affect. It would be interesting to see results on a cool cloudy day versus a hot sunny day. Interesting video. I just put a tuner on a very nice .22 LR so anxious to see how it affects accuracy at 50 yards and beyond.
I'd very much like to know the repeatability. as I have and mostly use a supressor and want to get this for some club matches. the idea of being able to remove and replace without reworking up loads is very appealing so repeatability is key to me wanting it
Browning used to have what they called the B.O.S.S. It worked great. I have a Browning Abolt in 270 WSM with a Boss on it and will shoot sub moa all day long, once i got it fine tuned.
Really interesting. This subject matter has been of many topics on several LIVE show, using a "barrel tuner or not"... And it really is interesting to see so many other there building a general census for the Pro's & Con's of this. Also worth mentioning, many of these folks that are already going on with this adventure of experimenting with a barrel tuner, of various brands and types, it will be crazy interesting to see the various calibers. Something so simple, yet, exceptionally complicated. These kinda remind me of the sky-scraper tuned dampers. (the multi-ton chunk of steel at the very top of the sky scraper to calm the swaying down), yet, it is just a chunk of heavy mass, hanging from cables, all the while ever so delicately balanced or tuned to the buildings harmonics.. I look forward to trying one in the future. I am a bit away's from trying one just yet, as my skill set is still too messy, to be able to notice a difference, as per, is the P.O.I. me, or the rifle system or weather, etc.... Soon though. that will be fun to play with a few of these various types of anti-harmonic / damper units.. Thank you for showing the graphs, I enjoy that seeing that kinda stuff, it helps my mind understand further what you are saying in a 2D format.. Thank you.
Great video guys the EC tuner brake sounds like a good idea and I think I'll give it a try one thing though you never mentioned how well it helps on recoil and if I'm not mistaken you use it only on a Mac grade barrel well how well will it work on a factory barrel would be nice to know and see the results well keep testing hope everything goes well and everything stays in the bullseye I like all your videos good going thank you for information that I might be able to use
I think to really tell if the tuner did anything you need a control sample of groups. For example, what would the graph at 5:26 look like if you just left the tuner on 0 and shot 7 3-shot groups? Obviously they wouldn't all be the same size. Is it possible if you shot 7 groups with the tuner on the same setting that you would shoot one group as small as .43 and another as large as 1.007? One 3 shot group is way too small of a sample to determine any statistical relevance at all. It is possible that the the gun shoots exactly the same on every tuner setting if a large enough sample of shots is used.
literally the cure to accuracy! eric cortina doesn’t play around everything he sells is 100% legit . great prices and the box it comes in is super badass
I think the best strategy to use a tuner is to tune a load for minimum ES and SD, then tune the harmonic to get a small group. When you do an OCW ladder for load development, you are tuning your load to match your harmonics, so if you tune for velocity and then for harmonics, you should be able to optimize both and find the widest node to shoot in.
Yep the BOSS-system: www.browning.com/news/tech-terms/boss-rifle-accuracy-system.html and www.browning.com/support/faq/tune-boss.html Still available on the BAR mk2 Safari apparently
What I would like to know is tuning for conditions. Say you go out in the morning and shoot. Then the weather conditions change effecting your load for afternoon shoot. Or a cold front moves through. Could you add settings to your dope for different conditions? And would they be repeatable enough to make it feasible?
Have one sitting on the shelf right now. Going to try it on my 6mm arc when I finally get the upper. (Of course do a baseline test with original brake first.) Haven't heard of anyone trying them on gas guns. Guess there's only one way to find out.
I have a 308 that I hand load for and a 300 PRC that I do not have immediate plans to hand load for due to lack of component availability. My question is do you feel that this brake is potentially a money/ammo saver for dialing in factory loads?
I want to try that brake system out on my 338 RUM... it has been a finicky round for me ... it has a 28" McGowan 1-9" twist barrel that is 1.062 at the muzzel and wonder if I might bennifet from this brake
If you remove the Magnetospeed from the barrel the group size will shrink even more! I've found that it GREATLY influences barrel harmonics which has lead me to the Lab Radar solution!
I ordered a stainless one for my 300PRC RPR but didn't get to install it yet. Then EC announced the black nitride ones so I got one of those for the RPR and the other is getting the ultimate harmonics test - an M1A in a M14.ca aluminum chassis.
I know this is 3 years old, but EC and others need to thank Winchester / Browning because this is basically the 2020 version of the early 1990's BOSS system. And it worked like a champ back then even though folks said it looked stupid on the end of a barrel.
May be a dumb question but I see you were using the magneto chrono. Being that it’s attached to the muzzle, won’t that play in to the barrel harmonics?
If you put gorilla tape on the back of your target it holds the paper together really well and you can get a better idea of the group size without the tearing of the paper.
Amen. I thought I was the only OCD guy doing that lol. Now I have a shotmarker on order.

Statistics of distribution do not favor barrel tuners. Two 30 shot groups, one without tuner and 1 with the tuner in a “node” could tell us definitively if the tuner works, but I’ve never seen this done.
Bought one of these for my .338LM. Worked amazing, love it. Loved it so much I just ordered another one for my 6.5CM. And I can't wait to see how much it changes things on an already great shooting rifle.
Another killer aspect of tuner is if you run data in temp changes and record it, you can tune load in colder/warmer weather. I run a 6.5 Lapua for PRS and it works. Without having 2 different loads.
I dont have one yet. And was wondering if that could be tested. Awesome info.
Bought an EC tunner for my 6.5 cm. My biggest surprise was reduction in recoil. I was surprised it has less recoil than my suppressor ( Gemtech 300 win mag). My last 3 shot group was .218
LOL, well, it is a muzzle brake.
Could you see the bullet trace down range after the break. My daughters are learning prs and I need them to be able to see the trace.
Erik’s tuner works great.
you really need to confirm those results with more than a single group
Yeah a 3 shot group only gives a 20% confidence interval for being within standard deviation interval.
I'm curious about conistancy. Maybe firing 3 groups per setting then averaging them. That way you don't get one crazy good group skewing your conclusions.
Would love to hear a follow up regarding removing it and demonstrating repeatability!
This is the interesting and fun part of marksmenship. Thank you.
Just bought an EC tuner brake. I’m having it installed now. Can’t wait to try it out. My best 5 shot group from my .308 is .478 with Federal premium 168 BTHP. This video has me really excited to see how much tighter my groups can get.
Have you had a chance to test it?
@@BLUELEADER78 I did a lot of shooting and testing this month. The EC Tuner brake did a fantastic job. I did most of my testing with Federal premium 175 bthp ammo. I did some testing with 168 and was able to tighten the groups down to .365 for a five-shot group. I ran out of 168 and switched to 175 BTHP. Before the EC brake my rifle would shoot the 175 in the 3/4 moa range very consistently. I started firing 2 shot groups at 0 going in increments of 2. At setting 2 they were touching but I continued on all the way back to 0 being 10. Setting 2 and 8 were both touching. 8 was very slightly tighter. I dropped back to 7 and went in half step adjustments. At 7 it had opened up to about 1/2", 7.5 was about the same, skipped 8, 8.5 was almost 1 hole but I could see it was 2 shots. Setting 9 was 1 hole, I couldn't tell through my spotting scope that 2 shots were there. I sent 3 more making it a 5 shot group. Subtracting the .308 for the bullet diameter the group measured .210. Thats a .518 hole with a .308! Wow, factory Remington 700 PSS .308 26" 1:12 twist with a Timney trigger and an EC Tuner brake is shooting factory ammo sub 1/4 moa !! Will it do it every day, probably not but that remains to be seen. I can say that I am a 100 percent believer in the EC Tuner brake.
Have a 7PRC will be installing a EC tuner brake!...I will send you my results when I have them...Good stuff guys thank you
I have the 30cal brake i swap on 6cm 6.5cm and 6.5-300bee. Set to original settings and it stays true. Takes half of the work out of load development. Erik makes an amazing product.
I was wondering if the 30 cal brake would be effective on lower caliber rounds, that is how well it would work to reduce recoil and tune .280 and .270 cal rifles. Sounds like it works on your rifles.
I picked one up a while ago and it works wonders on my rifles! It saves me a lot of time and money so I don't have to play around with bullet seating depth especially when getting components are hit and miss.
Yes, I use the EC tuner with a 6.5 PRC currently worthing with a load. The rifle is a new MPA with factory match bullets it shot well 1/2 with the turner .119.
Easiest thing to do would be to have a tuner for each rifle. But, I like the repeatability idea for those on a budget and want, or are limited to, that capability. I'm a fan of Erik and have learned a lot from his channel.
He's got a lot going right now and yes I've learned alot from him to very smart man
For those weary of the tuner brake; buy one and install it as if it were a standard brake. Develop a load conventionally with a powder and seating depth node that shoots well. When you go to a match and your groups start opening up because of throat erosion or change in temperature/pressure, you can adjust your tuner on the fly as a backup.
I think this thing can cut your load development time in half. It would be so nice to find a powder charge with low sd and then you could essentially finish your load development in 1 day at the range as opposed to making a bunch of trips back to your reloading bench
I have an EC TUNER PN A 40 cal muzzleloader. It truly does make a difference!
YES! Definitely test taking the EC Tuner off of the rifle, messing with the setting and then remount and set back to desired setting. I'd love to see that tested. I'm an Eric Cortina fan because he clears the muddy water stirred up for us who have less knowledge, he backs it up with proof
I inherited a browning ab2 .270 with the boss break on it. After shooting a 3/8” group 4 times, i really wanted to get a boss break for my other rifles, but found out that browning discontinued them. I am very happy to see the EC tuners are basically the same thing and work well. My savage 22-250 is about to be stupid accurate lol.
270 stomps ass, especially when loaded right, to it's full potential, absolute favorite all round cartridge, then the 7rm mg, ballistics are impeccable
@@travisweldmaster7815 I want to add a 7mm someday, but since I handload my rifles, I may get crazy and go 7 SAUM. Why it hasn’t caught on commercially despite being an F class King is a complete mystery to me.
@@fnkdtnk yeah no doubt it sure is, I custom built this one, off a savage action bull 416 barrel fast twist choate stock, was my first real precision build, If i could go back I would go saum too just because the belt can be annoying, the 280, an ai's an saums def rule f class, I load also my go to for that 7 is 168 ablr at 3150 fps, loaded out to almost 3.5 inches, nothing bad to say about any 7mm cartridge really...even 08 isnt bad, well comparably no but alongside most it does well the .284, .277 and smaller, I find you really have to push 30 cal really fast to not lob mortars like 308 lol I like 308 for fun just because it's so ballistically INEFFICIENT for a scope track challenge lol, ol slow and heavy is fun to pull out every now and then 175smk 42.5g sw pr 2650fps, 1 hole groups, basically a tuned federal gold medal factory load
@@travisweldmaster7815 my uncle in law is an avid hand loader and long range shooter. He recently parted with his 7mm rem mag specifically because he hated having to seat it to the belt instead of the shoulders. He had a 280 rem turned into a 280 ai and loves the thing.
I shoot 165 ablr’s out of my 30-06, and it is a mortar as well, but its strictly a hunting rifle, so I don’t shoot it far enough to really care. My .270 has swift scirricos, and they are about used up. I may swap it to ablr’s too, though I’ve heard great things about the eld-m’s, and they are significantly cheaper,
@@fnkdtnkI gotcha, nothing wrong with that, to each his own, I headspace off the shoulder to head like any other, like the belt isnt even there, no problems, but everyone's setup isnt always the same
Years ago I HAD 3 Winchester Boss System rifles, 243, 300 Win, 7mm mag. Each shoot 1/3 MOA. Sold them along the way..... About time someone came out with a Boss style system. I'll buy a few dozen.
One test I would like to see is to take the tuner out several rotations and see what happens if you go from zero to say 30. Is there more than one node that can be found and at what distance might that be?
Go to Erik’s site, he shows it. There will be several nodes found on running it out from zero.
I use the EC tuner break, and I like what it does for my Aero Precision Solus.
Gavin the EC TB works very well
I have a 6 ARC 22” bbl in a gas gun, would be very interested in getting a break, like the one you guys tested. My bbl has a 5/8 thread like the 6.5 Grendel has also.
I have the same setup as you and just got the EC tuner brake but haven't tried it yet.
Would love to see you do the tuner adjustment as shown. Then shoot a 20 shot group with the best and worst settings. Also, as others have said step back through the adjustment a 2nd time and see if you land on the same settings for best and worst groups.
I just got back from the range. I have the EC..2 tuner break, and it's amazing. I'm getting ready for hunting .
I loaded with no load development. I used 40 guns of Varget, under a Berger 175 grn vld hunter.
At setting 8 I got.25 inch group at 100.
I tried 7 and it opened up to 3/8".
I went to 8+ and it shrunk the group to 0.029 ,3 shot group. No load development.
I'm good for in the bush where my longest shot will be just over 200 m over a pond.
Use the tuner brake on my prs 22 br. 95 gr smk, h4350. Last group on paper was measured at .281-.224=.057 for 5 shots. Consistently shoots from .2-.0. Best shooting equipment I've bought!
This sounds like the product I may need. I had a load that consistently shot .5” inch groups at 100 yards with single digit ES/SD. Shot a 4” six shot group at 995 yards with that load. Then I ran out of powder and switched to a different lot of the same powder. For reasons I’m still scratching my head trying to figure out why the groups went to crap. I would have three touching and two fliers high and low. However, the velocity node stay the same with single digit ES/SD at the same charge weight. The velocity did drop approximately 50 fps though.
I also developed a load for a couple 308 rifles that have BDC reticles, is gas operated and the other is bolt action. The load I’ve developed runs identical ES/SD in both rifle, low teen ES and single digit SD, and the ballistics match the BDC reticle. The bolt gun shoots a consistent .5” five touching group at 100 yards, but the gas gun shoots .8”. I imagine this brake may shrink those gas gun groups down some more.
i like to see if it is repeatable and accurate every time you take it off and back on the rifle..... great vid you guys!
Yeah,I put a brake on a 25 WSSM AR.IT went from 1/2 “ groups to 1 1/2” or worse.Took the brake off,tightened up.So I have a EC TUNER brake on order .Hopefully it will not let me down
I've had a stainless Winchester model 70 in 30-06 for over 25 years. It came with the BOSS system...and was apparently way ahead of it's time. It is the same principle as this - a brake with a tuner. It's a shame it was discontinued. I dialed it in for factory 150gr loads when I first got it and it shot 1/2" groups...and it has shot them continuously since then.
@Phil Ward It was at the end of the barrel...very similar to the EC system.
I tuned mine for 168s and has been fantastic for years as well. No need to buy another rifle since. Have about 800 rnds through it now, so there's plenty of life left in it. My buddies that shoot it can't believe that the '06 could be that accurate. It can.
I didn’t know Winchester had the boss system I have only seen it on brownings I thought it was special to them.
@@dbuckner902010 Winchester and Browning are both owned by the same.
Good video and information. Been thinking about getting a tuner.
Thanks for a very interesting and practical experiment. Currently there is not a temperamental rifle in my safe, however if I do have issues the EC Tuner will be part of my solution.
I had a 6.8 SD but a.67" group. Added the EC-TUNER and got to setting "6"! One fricking hole! 😎
That is exactly what mine did, 6 was a one hole group. 6 Creedmoor.
Yessir, same experience I had...love it!
I knew I should of got on the black tuner list few months ago. Load work is done and want to see if I can get into 0.1
I have his EC Tuner Break in 308 and 6.5. shot a 3 shot 308 group tuned to #7 on the break.... Hole diameter was .398 on the target. Still working load data for the 6.5. Love the breaks
Yes area 419 hellfire self timing muzzle system groups are a lot tighter shooting 338 300 grain bullet can't wait push this out pass a mile.
I used the 30 caliber EC Tuner Brake on my 700 Remington CDL 7mm Remington Magnum and the difference was worth every penny spent. Results on my hand loads- three shot groups starting 0.78” we shrunk to 0.19” which essentially was one button hole. Never look back!
very cool product. unfortunately, my tuner is a suppressor. it only has 2 settings: on and off... i prefer the "on" option!
Good series with the two guys 👍 Gavin get's help from Travis 😁
When taking it off and putting it back on i would try and use a crows foot on a torque wrench to make sure the tightness to the muzzle is the same to remove another value from testing.
Bingo! Any ideas on how to ensure consistent timing?
I have a EC tuner on my Vudoo. So worth the money.
The browning Boss is just like the break. I have it on my a bolt 2 medallion 280 rem. It really works
I may have missed it, but it would be nice to hear if the brake portion of the tuner brake is effective also. I am on the fence now and don't like the brake on my current setup. Keep the great videos coming.
My feeling is as a brake it is very good.
So is it safe to say that using a magneto speed could alter your guns groups and make a good load look bad? My custom 270 stacks rounds in a 1/4 MOA group all day long but last time I shot it with my magneto speed the group's were about 3/4 MOA and I was confused because it was the same load. Now I'm thinking the magneto speed effected my harmonics.
I guess from now on during load development I'll only use the magneto speed after I find a load that groups well.
It can have an effect on the harmonics. I agree find a good load then use the chrono for data.
I just got mine today and installed it. Question do you work up a load and then start turning the tuner or grab any load
When you are setting up your rifle.....do you get the optimal powder and then did you add the tuner brake and start adjusting it?
Typically we start with the bullet we want to shoot then powder and powder charge. The tuner brake would come once you have hit the variable you are “aiming” for, low es, sd, or velocity. Then tune the brake.
Great video. So... With the EC tuner, a person could develop a very fast load and then use the EC tuner to tighten the groups. Correct?
Yeah basically your method would be run a ladder and pick the charge weight that has the smallest standard deviation on velocity. Then load up a bunch of that load. And take the ones you just loaded that are all the same load with your best standard deviation of velocity, and shoot a fire you shot group turn out the turner. Shoot another group. Turn out the tuner. And so on. By the time you've done say 50 rounds there you should have found a couple of nodes that are fairly accurate. You know I don't have to compromise between a harmonic node and a consistent velocity node you can choose both. You adjust your powder to be the consistent velocity and you adjust your barrel to be the consistent harmonic.
@@GunFunZS Thanks. I've been working up a load for my hunting rifle using Barnes 175gr .308 LRX with Superformance powder with CCI250 primer and Winchester brass. I've used Dan Newberry's OCW method and I tried the Saterlee 10-shot ladder test and they both gave me 58.0 gr of Superformance as the sweet spot. I then played with the seating depth, but my riflescope started acting funny and it turned out to be defective. I finally got a new/used Vortex Viper HS-T 4-16x44mm scope 2 days ago so I hope to get back to the range soon and finish the load development. Cheers!
@@onelegwest I'm willing to bet money on two things. 1 you were probably a much better shot than me. 2 The defect of that rifle you rejected was probably more than sufficiently accurate for the hunting you're actually going to do with it.
And the third thing that I won't bet on but do suspect is that you will end up with a very accurate load by the time you are done.
Remember the boss system on Browning and Winchester rifles in the 90s it too was adjustable
I had a 22-250 with the Boss and within 20 rounds I had less then a 1/2 inch group at 200 yards. If this is even close I want one
I still have my model 70 sporter boss in 3006
We have the BOSS on a Model 70 in .270 and another on an A-Bolt Eclipse Varmint in .308, I don't know why they stopped producing them as they really work well.
What is the name of that trigger ball head under the spotting scope? I am looking for a quality ball head like that. TY
The EC tuner is a great product. Need to try the. 30 can version.
it’s a great product man . i work for eric in his shop everything he sells is great .
@@cedricmendoza1305I just tried to buy one the website states out of stock , will these soon be available again ?
Would this make any difference on a carbon fiber barrel ???
On a Christensen MPR 6.5 Creedmoor ????
Yes, I have mine on a Crbristensen carbon fiber 6.5 ca10dmr - great success
I'm curious how ambient temperature would affect tuner results. I suppose if powder burn was exactly the same at any temperature, there would be no affect. It would be interesting to see results on a cool cloudy day versus a hot sunny day. Interesting video. I just put a tuner on a very nice .22 LR so anxious to see how it affects accuracy at 50 yards and beyond.
Well what happened?
I'd very much like to know the repeatability. as I have and mostly use a supressor and want to get this for some club matches. the idea of being able to remove and replace without reworking up loads is very appealing so repeatability is key to me wanting it
Picked up a browning gold med it had a tuner on it never seen one before kinda neat.
I owned a Browning A bolt in 300 win magvwith the Boss system. It was awesome!
Browning used to have what they called the B.O.S.S. It worked great. I have a Browning Abolt in 270 WSM with a Boss on it and will shoot sub moa all day long, once i got it fine tuned.
Is this something that would fit on a Remington 700 25-06? Do I have to cut threads onto the barrel or does it connect some other way?
The barrel would need to be threaded by a smith.
You just got a new subscriber mate!
Really interesting. This subject matter has been of many topics on several LIVE show, using a "barrel tuner or not"... And it really is interesting to see so many other there building a general census for the Pro's & Con's of this. Also worth mentioning, many of these folks that are already going on with this adventure of experimenting with a barrel tuner, of various brands and types, it will be crazy interesting to see the various calibers. Something so simple, yet, exceptionally complicated. These kinda remind me of the sky-scraper tuned dampers. (the multi-ton chunk of steel at the very top of the sky scraper to calm the swaying down), yet, it is just a chunk of heavy mass, hanging from cables, all the while ever so delicately balanced or tuned to the buildings harmonics.. I look forward to trying one in the future. I am a bit away's from trying one just yet, as my skill set is still too messy, to be able to notice a difference, as per, is the P.O.I. me, or the rifle system or weather, etc.... Soon though. that will be fun to play with a few of these various types of anti-harmonic / damper units.. Thank you for showing the graphs, I enjoy that seeing that kinda stuff, it helps my mind understand further what you are saying in a 2D format.. Thank you.
Great video guys the EC tuner brake sounds like a good idea and I think I'll give it a try one thing though you never mentioned how well it helps on recoil and if I'm not mistaken you use it only on a Mac grade barrel well how well will it work on a factory barrel would be nice to know and see the results well keep testing hope everything goes well and everything stays in the bullseye I like all your videos good going thank you for information that I might be able to use
I think to really tell if the tuner did anything you need a control sample of groups. For example, what would the graph at 5:26 look like if you just left the tuner on 0 and shot 7 3-shot groups? Obviously they wouldn't all be the same size. Is it possible if you shot 7 groups with the tuner on the same setting that you would shoot one group as small as .43 and another as large as 1.007? One 3 shot group is way too small of a sample to determine any statistical relevance at all. It is possible that the the gun shoots exactly the same on every tuner setting if a large enough sample of shots is used.
Did you find it was repeatable? If you take it off a rifle & use it on another then replace do settings stay the same?
My buddy has a tuner on his 37xc as well as a terminator muzzle brake! They absolutely positively do work , I’ve seen it first hand…
Tuners can help shot placement. small caliber rifles can use improvements on shot placement. It really helps when hunting, large or small game
literally the cure to accuracy! eric cortina doesn’t play around everything he sells is 100% legit . great prices and the box it comes in is super badass
What is the cost of this tuner/ brake ?
So you find the node and reduce group to minimums. Can you then mimic the tuner with a static accessory so the tuner can be used elsewhere ?
I think the best strategy to use a tuner is to tune a load for minimum ES and SD, then tune the harmonic to get a small group.
When you do an OCW ladder for load development, you are tuning your load to match your harmonics, so if you tune for velocity and then for harmonics, you should be able to optimize both and find the widest node to shoot in.
100%! That is something we talked about in the vid.
Around the 12 minute mark I really liked your questions, is there a part two to this video where you guys test repeatability and such?
Gotta get one.Been waiting on EC to get his new Mill all lined out
Very interesting. I remember Browning came out with a similar setup in 80s or early 90s I think.
Yep the BOSS-system: www.browning.com/news/tech-terms/boss-rifle-accuracy-system.html and www.browning.com/support/faq/tune-boss.html
Still available on the BAR mk2 Safari apparently
@@gusmodelmaker YES!! That was it.
I was wondering if this was different. But except for the muzzle break I guess not. Cool piece of gear for sure.
What I would like to know is tuning for conditions. Say you go out in the morning and shoot. Then the weather conditions change effecting your load for afternoon shoot. Or a cold front moves through. Could you add settings to your dope for different conditions? And would they be repeatable enough to make it feasible?
Have one sitting on the shelf right now. Going to try it on my 6mm arc when I finally get the upper. (Of course do a baseline test with original brake first.) Haven't heard of anyone trying them on gas guns. Guess there's only one way to find out.
I have a 308 that I hand load for and a 300 PRC that I do not have immediate plans to hand load for due to lack of component availability.
My question is do you feel that this brake is potentially a money/ammo saver for dialing in factory loads?
I have 2 a 6.5 creed and a .308.
THESE WORK!.
I want to try that brake system out on my 338 RUM... it has been a finicky round for me ... it has a 28" McGowan 1-9" twist barrel that is 1.062 at the muzzel and wonder if I might bennifet from this brake
Erics Tuner Brake will cut your recoil in half.
If you remove the Magnetospeed from the barrel the group size will shrink even more! I've found that it GREATLY influences barrel harmonics which has lead me to the Lab Radar solution!
Exactly. Always wondered why people shoot for groups with the magnetospeed on the barrel. You are effecting harmonics of the barrel.
We did not shoot the final test groups with the Magnetospeed on. We did test with it on as the video shows. The results are all from the tuner.
@@Tfox31 this is exactly what I do. I use the Magneto for velocity mode testing...then you shoot groups to adjust bullet seating.
I ordered a stainless one for my 300PRC RPR but didn't get to install it yet. Then EC announced the black nitride ones so I got one of those for the RPR and the other is getting the ultimate harmonics test - an M1A in a M14.ca aluminum chassis.
Exellent vid Gavin.
I watch Erik Corrina's TH-cam channel. He's really funny. Plus, he has a lot of good advice for people who want to get into accurate rifles.
I know this is 3 years old, but EC and others need to thank Winchester / Browning because this is basically the 2020 version of the early 1990's BOSS system. And it worked like a champ back then even though folks said it looked stupid on the end of a barrel.
May be a dumb question but I see you were using the magneto chrono. Being that it’s attached to the muzzle, won’t that play in to the barrel harmonics?
