Testing Neck Tension in 223 - UNBELIEVABLE Results?
ฝัง
- เผยแพร่เมื่อ 12 มี.ค. 2022
- The Best Neck Tension setting is something we all want to know. In this video we test to see how Case Neck Tenison affects the performance of our reloads with Short Action Customs Bushings in 223 Remington. Neck tension is tested in 10 different bushings to see changes in velocity, statistics, and group size.

Richard Lee made an interesting statement is his Modern Reloading book. He basically stated that if the neck of the case is more than 0.001 inches less than the bullet diameter, the bullet serves as a conventional expander. He also said that a bullet does not make a good expander and would create excessive runout. In my opinion, since the brass used in your comparison test is random range brass, the data provided may be inconsistent due to other variables. It would be interesting to see this test done with a consistent lot of new, quality brass such as Lapua. Another useful aspect of this test might be to carefully remove a set of bullets after they had been seated and measure the inside diameter of the case neck. This would test the validity of Richard Lee's statement regarding the bullet acting as a conventional expander.
Great video! I’m a complete geek when it comes to reloading and your data is clear and concise. Thank you!!
Hi Chris! Glad you enjoy it
Great info
I bought SAC bushings after your first video, and they do work. Fantastic bit of kit!
I am glad they are working well for you!
This is exactly what I need as I want to buy SAC neck bushing for 223 Rem. Thank you very much for your work!
Glad it was helpful!
Wow you have gone deep into the reloading since the last time I watched your channel
Thanks for the video Enjoyed it,as always learned much,see you on the next one brother.
Glad you enjoyed it
Another fantastic and informative video!
Glad you enjoyed it!
I have a IGaginh digital ball micrometer I bought 3 years ago. Still going strong and I like it
Thanks for the video information.
Hope you found the info interesting.
Interesting............ thanks for sharing.
Thanks for watching!
One point to be made when ordering bushings, is, if you have various brands of brass, check them all with a loaded bullet, you may well need more than one or two bushings because of the wall thickness on different brands.
Hi Dave you are absolutely correct. I am just trying to give a general guidelines.
Or neck turn for uniform thickness
Could you do a video on the AR your using(ie bolt carrier, bolt, receiver ect) to go along with that White Oak Barrel which are a deal for the accuracy. I’m wondering if the muzzle is threaded and are you using an adjustable gas system? Did you loctite or use shim stock on the barrel extension during installation? Great video thank you!
Something to consider if it's a auto loading is that if neck tension is light enough the projectiles will shift to touch when cycled therefore alter coal possible to a better harmonics position. Not that this is the cause of the smallest group but it does need to be considered. Seating depth with have the largest impact on group size a closer distances
Love it
Looking forward to the retest results!
You and me both!
Another great video - thanks!
I'd love to see indicated runout on the inside of the neck rather than the outside. Difficult to measure though. I feel any bushing die pushes neck thickness inconsistency toward the inside where it hurts most. As such, I use a mandrel die to true this up.
HI Kevin, The runout measurements on the chart on the the seated projectiles. The video clip I show is historical footage from the original comparison. That said, if your brass is at all decent there is no chance that your going to measure .005" TIR on the outside of the case and the ID is going to run true. I am going to include other charts data in future videos to show this but I was try to do a raw comparison of bushing to bushing. If you use 3 different bushings with the same expander would it vary? Not sure but it is a question I hope to put data behind in the future.
@@BoltActionReloading I get what you say, and agree that we really don't care about the loaded or unloaded neck TIR. What matters is the consistent contact on the inside of the neck and bullet and hence suggesting devising a way of measuring any inconsistency there. A loaded bullet may have minimal TIR while making inconsistent contact with the inside of the neck.
I'm considering a Redding type s full length bushing die with SAS bushings. Currently I'm running a Forster full length die, but with the expander ball removed, and then a Wilson mandrel to get the neck tension I want. With AMP annealing on every firing I'm getting highly predictable results. However... I've not found a way to accurately measure inside neck TIR.
I'm learning every day and look forward to your next video :)
We are all learning, myself included. I am very frequently surprised by some of the results I get. I am going a little overboard in 223 probably because its a little cheaper to test and take what we learn here to other calibers. I have had good luck with your method as it is the same one I use at this moment for my target loads. Though as I go through this exercise, I may change. I feel that 223 is actually more difficult to load for because of the shorter neck, lower case capacity, (I am thinking that the variation in powder measurement is a higher percentage of case volume and makes lower ES/SD more difficult to achieve) and being forced to seat past the neck shoulder junction. I also was concerned at the accuracy limits of this platform but being able to get several groups 1/2 MOA or less encourages me that there is potential here. The factory I have tested shows ES 70+ over 10 rounds so every single option I tested is no where close to that. Glad you guys enjoy the videos!
@@BoltActionReloading I'm personally glad you test 223 as much - I run a Tikka T3x TAC A1 in 223, so getting a lot from these videos :)
@@ShootingAndReloading Where did you find it? Ive been looking for a 223 CTR for a long time now
New to your channel and kudos I really like it and have learned quite a few things in a short time so thank you. One question I do have is was the brass annealed prior to resizing for your tests?
Hi Mike, I anneal pretty much everything before sizing.
@@BoltActionReloading that’s what I was thinking but wanted to ask. Thanks
Hi Mike, no problem asking. Welcome to the channel! Don't be afraid to ask questions. I try and get back to them all when I can. Sometimes TH-cam's notification system for me isn't perfect so if I miss one here and there try and forgive me.
Very very interesting
Glad you think so!
Great video! 👍 two questions though. I'm assuming that your WOA barrel is on a gas gun? If so, are you using the magazine to feed or are you single feeding? Also, I miss your data page that lists the load data. That was nice to see in your older videos.
Hi Jay, Yes its is. I am feeding from the magazine. I will probably bring it back I was just trying something different.
Just purchased the 243 bushing to start playing with neck tension probably work my way to 245.
It would be interesting to see the actual inside diameter of each bushing. The results from the redding bushings may indicate the diameters are out of spec. A few of pin gages would tell the tale.
I did use pin gauges for the sizes that I had 243 and 244 and the fit the labeled bushings appropriately. I don't have pin gauges for the 245, 246, 247, and 248 at this time.
White Oak 416r Barrels
I have the same disease, OCD reloading 😁😆😅
Love your Channel very good information and with data to back it up. But I have a .223 using LC brass bought a 245 originally but I could push the bullets easily. I contacted SAC and they requested pic of the calipers measuring the brass. They were nice enough to switch the bushing since I had just purchased it. They recommended 243 and I get good groups. So what changed? Thank you.
I am not sure what your seated dimension is. 3:10 in the video I show the what the example is based on. I wouldn't think there was that much variation but you should usually be .002 to .oo3 under this dimension.
All tutorials about neck bushings and what size works well fail to mention what size mandrel is used for each bushing size or is a one size mandrel used for all bushing sizes and what size is it?
Another method used by erik cortina is to use a bushing that takes it a little below desired neck tension, then use a mandrel to set the final dimension. You could just use a normal die amd then mandrel, but the purpose is to not over work the neck. I plan to try this soon on my new 20 practical. Also, annealing is going to change tension without changing the method.
Erik also doesn't clean the inside of the neck, which reduces the coefficient of friction and prevents a true cold weld.
Have you tested to see if runout less than .004” blows up group size? Runout is the the very least concern I have with handliading.
I will say but then again I don't know what brand barrel this rifle has. Either way your doing a good job and your. On the right track, however for me testing that is a lot of shots testing if the barrel was not cleaned in between out of all that testing. Could very well answer your velocity difference. Like I said though your doing things pretty good here. I have found standard redding bushings to be a little off what there supposed to be at times, I have not had problems with the TIN coated ones though, I also never had one that was off measurement from l.e. Wilson either. But I like the looks of the short action customs bushings, look almost like a pvd super slick coating on them. Good video
This is a 18" SPR barrel from White Oak, 1:7" twist. It is very similar to the one JRB uses if I am not mistaken. I don't remember what length gas system he is using.
Since using the two step method of redding body die to bump the shoulder 2th and lee collet neck die I've been getting 1.5 Max in run-out, cheap set of dies and they work for me
What's the clamp you have that's holding the micrometer
There is a link in the description to a micrometer stand.
Were you able to repeat that small group?
This is great data, thank you. So I take it you run a 21st century mandrel or turning arbor through the neck _after_ sizing with the Redding sizing die with the SAC bushing? I’m just confused on this one point, because you have referenced both systems to reduce runout. I have reduced runout quite a bit by just using a 21st Century mandrel after sizing with a std sizing die and calling it done. Thanks for any info.
I was going to ask the same question. It wasn’t mentioned if a mandrel was used after sizing.
I really think this is due to the short action custom bushings only sizing half of the neck vs Reddings that size the entire neck. (all the way thru the bushing is the same diameter vs SACs bushings that only size halfway thru the bushing.) This is why you have to go 1 size smaller on SAC bushings to get the same tension, I am sure. If your data is correct then it must be helping groups I cannot argue that. But why is only halfway sizing the neck (approximately) doing that? I would love to see this test on good Lapua brass with the inside and outside necks turned /reamed for consistancy.
I think internal diameter of case mouth is what we care about, not external. And wall thickness may vary from case to case. All that makes me think that Lee collet die would provide more consistent neck tension then any die with bushings.
Hi Alex. If you would like to see how different options change these things I have a video here that includes the Lee collet die: th-cam.com/video/b0igSmCMTfw/w-d-xo.html
@@BoltActionReloading I saw that video before, thanks. At my view force profile of resizing process is irrelevant. I think two things matters though : 1) seating force 2) concentricity
Great video, and love your sense of humor. "You could probably get this accuracy without the fancy tools, but what fun would that be?" Or, "Many will draw their own conclusions, even though you weren't there to witness the testing". I has a plaque hanging in my office that said, "Without data, you are just another opinion". Seriously, this is excellent test data. I have pretty much gone away from using my Redding S dies and bushings due to the run out issues, and after FL sizing, run the brass over a 21st Century black nitride expander mandrel. I'm considering going back to the Redding S dies and SAC bushings, then using the 21 Century black nitride expander. Your thoughts?
Hi Gary. I appreciate that very much. Sarcasm was my 1st language, but I try to keep it to a minimum. I really wish I had a larger number of samples at each option, but sometimes the total number is getting out of hand. If you like the force graphs you will appreciate what's coming. (at least I do, but I am clearly biased.) how you size your brass changes these graphs, (I know shocker right) but correlating them to the accuracy is the hard part, but I am working on it. I spent 3 days the last 2 weeks researching how to write VBA code to automate some of the data processing tasks so hopefully the next ones I test will be faster.
Back to your actual questions. I had pretty much abandoned my s dies until I found these bushings, but I have bought more so we are going to test it all. (eventually) SAC has been kind enough to provide the bushings, so I am going to try and get the testing results out there. I have not tried any of the new black nitride expanders from 21st century, I see they have a option at .001" and .002" under caliber diameter so I would get both if I made an order, then how many calibers? Have you used any of these new nitride expanders yet? I have had several folks ask, but don't have any feedback for how they work.
@@BoltActionReloading Yes, I have used a black nitride expander. I had been using an expander from L. E. Wilson with a stainless mandrel. I was a bit surprised at the force to expand the necks, and the amount of brass deposited on the mandrel which caused me to purchase the 21st Century black nitride mandrel. I was blown away by the ease to expand. I use Redding dry neck lube when expanding necks which made quite a difference with the L. E. Wilson mandrel, but little difference with the black nitride mandrel. Might be another project for your AMP force gauge, to measure the difference between SS and black nitride mandrels. Thanks again for your efforts to enlighten the rest of us.
@@garysreloadingroomReloading I've run into the same issue lately, sometimes the force required to run my SS Sinclair mandrel through a case. I read in your post that you are pleased with the 21st Century black nitride mandrel. Did you have to buy the 21st Century Die Body? I use a Sinclair die body. Thanks!
@@kenhatley1041 Merry Christmas Ken. I honestly can't say for certain that I have used the black nitride 21st Century mandrel in anything other than the 21st Century body. I just went through my reloading tool cabinet and couldn't find my L. E. Wilson body and expander (think I gave it away). On the 21st Century website, they state "21st Century Expander Mandrels and Arbors are designed for proper fit in our die bodies. While these may work in most Sinclair and PMA die bodies we cannot guarantee proper fitment in those bodies." You might order a black nitride expander and see how it fits in your Sinclair body. I'll bet it will work just fine. All my testing has been performed on annealed brass, and although I don''t have a seating force gauge, my seat of the pants feel for seating pressure was enough to sell me on the black nitride mandrel.
@@garysreloadingroom Merry Christmas to you as well! LOL, it sounds like you and I share the same reloading techniques! I do not have a force gauge either. Just as you commented about your "feel" for the force required to expand, I experience the same. The comments made on this thread, as well as other forums, make perfect sense about using a mandrel to expand necks. I think I will go ahead and order the 21st Century and cross my fingers that it will fit!
I've been reloading for about 40 years but just started "precision" reloading a couple of years ago so I am trying to learn as much as I can! Couple questions for you: do you size the brass (with a bushing) and then expand the necks with the mandrel?
Do you use 21st Century's Moly Dry Neck Lube when you expand case necks? I have always used Reddings Imperial Dry Neck lube and therefore have no experience with any other products.
Thanks so much for your feedback!
Thanks for the great video. Probably a stupid question: Can you use these bushings in a redding 308 Win B/FL 9R Die, or are they only for Short Action Custom Dies
They are not just just for SAC dies. But I don't think the model you list there is a bushing die is it?
@@BoltActionReloadingThanks for the reply. Yes, the redding code is 77155 (sorry for any confusion)
Yes they will work with that, in fact I plan on doing a similar study with that exact die in my 308 Win at some point in the not too distant future. (I already have the bushings) I was using 223 as the first run to see what adjustments I should make when I do other calibers.
I've had guns that shoot good with light and others that shot food with tight neck tension.
Wouldn't the total seating pressure be the area of the graph below the curve?
I wish you had said on the first video that these great bushings did not size the case till further down dude. The mouth of the case is very important in starting the tension on the cartridge. Oh well that’s what I get for listening to TH-cam videos.
Have you ever tried the Wilson's bushings? cuz they are also slightly tapered internally, perhaps not as much as the SAC though. Wilson's bushing FL die is also better than Redding's. Thanks
I have not tried Wilsons bushings. I know that my run out flyers have basically disappeared when I started using the SAC bushings.
So... did those results stand.. Still shooting .25" groups with that tension and the .246 SAC bushing?
I have 6.5mm, .30 cal and .338 I need bushings for. I'm going to try Redding bushings first . I know I will need 2-3 bushings for each caliber. They retail for 15.95 ea at Creedmoor. Reddings Titanium bushings are 26.95! The SAC Bushings are 35.00 ea from them. Yikes! I cant imagine Reddings being inferior quality. It appears the big difference is the SAC bushings only sizing halfway thru the bushing to me. Anyhow, that cost difference is $143.00 vs 315.00! I will check the runout on 2 different measuring systems and find out if my runout measurements are as inconsistant as yours. I am using Lapua Brass tho, not range pickups.
Can the AMP press be used to decap and resize brass with the LE Wilson dies like you can with a arbor press?
The AMP press is just to measure bullet seating force, or at least that's all I have ever used it for.
Could you kindly help? Can I adjust the redding type s die to get more neck coverage with a SAC bushing?
Adjusting the top screw down to touching the bushing and then backing off a 1/8 or 1/4 turn to allow the bushing to float is as much as you will be able to size the neck. That has been plenty for anything I have used them in including 223 and 300 win mag.
Can you compare and contrast bushing dies vs. mandrels? Ive only used a FL die so far.
What exactly are you looking for. I have some pretty detailed stuff in this one: th-cam.com/video/b0igSmCMTfw/w-d-xo.html
Using range brass , you can't place a value on seating force per bushing size. This is the type of details that bothers me because the data is screwed
How confident are you that the projectile didn't move during the shooting process on the SAC .246 sized cases, causing a change in COAL/CBTO and that's what actually caused the better group?
I did not test setback. I initially did not intend to show any group data, it will have to be revisited. I would have personally expected the groups to open up and be less consistent.
That's what I was thinking. Maybe those bullets slipped out to the lands.???
I have the Redding .308 die. Would I want the SAS bushing that is .003 smaller than the bullet? .305? How do I get the ID consistent? FL die with certain size Mandrel? Apologies, but I'm new to this. I'm not new to reloading but I am to specific neck tensions and being more consistent. I have an AR 308, a bolt 308 and a 300 Win Mag, oh and a 7 RM.
HI Gary, I am going to cover this exact caliber (308 Win) if you can wait. Usually you would go .002 to .003 under loaded round diameter. If you were going to mandrel .002 under is a good guess. I did a version of this with mandrels already but I want to add the amp press graphs so I will be doing it again. th-cam.com/video/OMEi5eHTLxQ/w-d-xo.html
Got a question.
Have you ever had a fl bushing die that you were using to bump shoulders. 002 and the bushing wasn't allowing it to bump size..
Take the bushing out and then it would bump the shoulder back
That sounds very unusual and I don't think I have ever seen anything like that.
@Bolt Action Reloading do you by chance have a redding #12 shell holder that you can measure the thickness of.
Someone brought it up to me that it could be the shell holder, I'm using a rcbs shell holder... it might be a tad to tall
What exact measurement are you looking for? Top of the shell holder to where the brass sits or somethings else?
If that is the case, that dimension is .1241" on my #12 redding
Just found your channel. Question, if you set neck tension, is there a need to crimp? I'm just reloading 223/556 for my ar
Hello kfez, Welcome to the channel! If you set enough neck tension you may not need to crimp. If there is a cannelure, I may think about it but if not I have not been doing it personally. You can test and see if you have a issue with the COAL changing and see it if matters for you. It also depends if you want to prioritize accuracy vs function. Every time I have tested it I seem to be loosing a little accuracy by crimping, may not matter to you at all.
BAR
@@BoltActionReloading thank you for your time. I'm just getting in to reloading, so I may have a ton more questions. Thanks for putting out good informative content
Neck tension low enough that the bullets slid forward to seat in the lands when being chambered? Where you able to eject a chambered round and have it stay together?
I will have to retest. I did not expect it to perform well. Like I mention in the video, its probably too low, but you can bet I will find out.
@@BoltActionReloading this was my thought as well. A good test would be to put one of the 246 rounds in the bottom of a magazine and then check it’s COAL after shooting the other rounds but before chambering that one.
Appreciate your work! Am wondering if that awesome group from the SAC246 bushing retained its original (as reloaded) overall length when violently chambered by an auto? Just a thought.
OBTW, your videos tend to cost me money! But as you said, what fun would it be if it didn’t. Words to that effect.
I think you need a sock puppet on your hand! 🙂
If running light neck tension, i.e., .001"-.002", does brass spring back play into the equation?
Hi Tim, Some spring back should be expected, and it will be different if you anneal or you do not.
What is the proper neck wall thickness to get consistent neck tension?
If you ask 10 guys you'll get at least 11 different answers. I believe that some of the 6ppc guys turn to like .008". I am guessing its at least minimally caliber different and also depends on what the inside neck diameter of your chamber is. The general rule I have heard is .005" of clearance between loaded round diameter and your chamber neck diameter so it has plenty of room for the case to expand. The next question will be how much of the neck you need to size.😀
Bomb Mics!
?
I think Doug likes your micrometers.
Lemonaid Yes
Have you tried using them with an expanding mandrel?
I will be but I haven't yet
I load 223/308 and use to "chase" the lands. Found my best loads at standard COL. I use Dillon dies so I haven't played around with neck tension.
Did you run a expanded mandrel or just bushings
Hi John, Just the bushings in this case. Initially I had just planned to show the real changes in neck tension with the bushings. I figured this was craze enough. Running and expander changes the profiles more than I would have thought.
Whoa man, where u get that fancy spinny thing?
Cheap turntable on amazon. I think it allows folks to get a better view of things.
@@BoltActionReloading I agreed !
First if all i am super new to reloading, actually i have not even loaded my first round yet. But i will say Brownells is very happy with the order i just placed lol. Your video have been such a huge help to figure out how to get started but even more, how to develop a plan for reloading uber precision ammo. I love the graphs and the deep dive into the results, please keep it coming!!
Ok…… now for my question. I ordered SAC bushings, when i reached out to SAC for their recommended bushing size and recommended mandrel size based on my loaded round OD of .292 i was told to order a bushing of .287 and a mandrel of .292 to obtain neck tension of .002
Thoughts? Should i be concerned about over working the brass?
Again thanks for all you do!!
Are you using mandrels with this neck bushing sizing?
Not for this test it was all bushings unless listed otherwise.
Each time you do a test with Short Action Custom bushings I try to buy some and they are sold out.
One question, is there any bullet lube or lube in the neck that you use or is it bare metal? One F-class guy I watch says there should be some sort of lube.
I am going to do some neck lube tests. These are just whatever carbon was left after cleaning and brushing the necks. I am probably going to deep here in 223 with the neck tension stuff.
@@BoltActionReloading More good stuff to look forward to, thanks!
How would a crimp affect this since its a semi auto? Assuming they're all consistent neck lengths.
I don't typically crimp anything, maybe if it had a cannelure. I have added this option in this series th-cam.com/video/b0igSmCMTfw/w-d-xo.html but I have seen groups open up afterward. JRB did some testing on this a few years back th-cam.com/video/wnZWv38cNKw/w-d-xo.html
How do you determine BC
Too bad you did not include the L.E. Wilson bushings. They allow either a straight diameter sizing, or a taper to size sizing by flipping them over. They also size less of the neck length as the SAC bushings.
I may have to give them a try at some point. So many things to test, so little time.
@@BoltActionReloading Well, if you sell your children onto the slave market, you can devote full time to the TH-cam crowd. Just comes down to priorities. Every test leads to more questions, a never ending quest.
ROTFL😂
Very interesting video - with that being said, I really don't have the time to get this "involved" with my brass prep. If you could pick just one brand of brass that would be the most consistent in it's critical measurements, what would you pick? Thank you for your time.
Lapua is a great brand and they have a steady supply chain.
@@ironDsteele Thank you!!!!
Hi Steve, its hard to go wrong with Lapua brass. I didn't expect most folks to go to this level of research. I guess I do it so others don't have too if that makes sense.
@@ironDsteele Peterson. Very underrated.
@@BoltActionReloading no love for Peterson?
what about 556 or is 223 data the same?
So feeding from the mag on a gas gun? I assume you didn't use a crimp?
Correct
I would MUCH rather have your AR Comp than the bushings.
Took me a long time to find it, but there are more powders out there.
How many data points do you look for to be conclusive? Do you have a number? In science they like to have at least 100 per item. Since all of your videos are data driven. Do you think you have enough data to be conclusive, or is it just for an idea for a video?
Hey Guys, dear @BoltActionReloading let me have an ambiguous question for you, which is totally not clear for me and may put some new light on the subject. Lastly I found videos about this gauge th-cam.com/video/LMOx9nBBJzY/w-d-xo.html and it is also used for light "hammering" the neck. The thing is that the action is performed on fully prepered ammo, the run-out measurement is taken from body (not the neck) and the pivot is hitting the neck with projectile already seated. Am I missing the point of this device or in fact it's changing the bullet seat and can worsen neck run-our? What is the reason to hit the neck (with already seated bullet) and measure change on the body. Is it anyhow possible to improve total concentricity (to streighten the ammo) without any influence on neck and projectile seating?
I decided to ask this question here because I believe this channel community have great knowledge and experience. I'll appreciate your help to understand the approach described. Cheers
Hello Sir, You ask a very interesting questions that many will disagree on the answer. I have not tested this type of functionality before because impacting the case on the most fragile part hasn't made a whole lot if sense to me. Though we all like small groups, this appears to possibly be more geared towards benchrest folks not to say you couldn't use it for what you like. Hornady's tool allows for something similar but I pretty much tried to fix my concentricity in my sizing die not after I had seated the rounds. If you decide to try it out let us know how it works for you.
It's silly to refer to it as "neck tension" - it's like saying a car's MPG is 16 gallons (the size of the gas tank). We're measuring neck compression - we should call it that.
You can call it whatever you like, just don't call me late for dinner!
Compression is static. Tension can be dynamic. Tension is the accurate word.
@@ChristianJHosbach So if someone squeezes a lemon with 1 ft/lb of pressure, the juice will come out just as fast as it will at 10 ft/lb? Guess the engineers at supersoaker wasted their time. Guess that also means I can inflate my tires to 10psi now instead of 35.
@@BoltActionReloading LOL. I'll call it "neck tension" because that's the norm/standard. ;-( Seriously though, I GREATLY appreciate your channel and all your time and effort you put into this. Also, you're the only person I've heard discussing the application of reloading to hunting that has talked about need of precision to ensure ethical kills (that's why I load my own). Respect!
Glad you enjoy the channel. I pretty much only hunt with my reloads any more. I think is just more of a confidence thing. The more factory you test, the more I am surprised the accuracy that some are able to achieve with it. Not trying to sound like a snob, but I know I passed up an elk because there is no way I could make a ethical shot with the platform and ammo I had at the time. Spent so much money and 10 days of my life and came home empty handed. Never again. These days I would be 100% confident that I could make that same shot, but I haven't made it back, Yet.
Redding Body die. Lee Collet Die. Seperate expander to 0.001. Forster Seater. And then whats Runout?
5 shots.. you'll have to verify with a better sample
Are you crimping? Stupid question but my OCD needs to know.
