I have had very good results using Strelok Pro in both RF and CF. Generally input average FPS measured with the Magnetospeed and one "correction" using actual dope on target at distance and I'll never have to make any corrections again regardless of temperature. I only need to take a Magnetospeed measurement when moving to a new lot number for RF. I try and always take measurements pre match for CF but only because I was shooting factory bought ammo. Once I returned to loading my own ammo, one session is generally good enough. Confirming the day before or the day of a match for that location if time permits. This is where the MS outshines the LR. Especially if you have a chassis mount ready to go. Just attach, plug in display and you're GTG. Thanks for the video as well. Very informative and exactly what I was looking for when searching.
I've noticed with my Labradar I get much more consistent results if I use the raw data off of the storage card & fit the data in Excel. I think most of my problems are due to using a muzzle break on a centerfire rifle adding noise to the first data point for a shot.
Hej Matt, great video 👍 which ballistic profile(G1,G7, RA4) is best to use in Strelok Pro for rimfire. Also what BC do you enter for SK RIFLE MATCH ammo. Thanks. Regards from Ireland 🇮🇪
I have done similar tests including using a third light curtain chronograph. As you noted, the positioning of the Labradar is critical to the results... The problem with such a point is in what it would take to validate that it is adjusted correctly without something to measure against such as the magneto speed. Unless someone goes out to test loads with an array of redundant systems, any particular means of measuring velocity is suspect. I have found outliers in all 3 velocity measuring systems and found no evidence that one is all around better than any other. The magnetospeed is the worst of all in the sense that it most affects accuracy, either by affecting barrel harmonics or by sympathetic pressure which deflects the round away from the magnetospeed.
They make a lot of mounting options to get the magneto speed off your barrel for around $100. That is still a few hundred dollars cheaper than the lab radar.
@@Prometheuss.cannabis.corner I am aware of that but thank you for the suggestion. A guy can get creative and make something easy enough for much less than a hundred dollars.
While at the range about a year ago, I had my Labradar and a guy had his Magneto Speed. We were off about 4fps. Both are accurate, just need to set up the Labradar up correctly. I have the trigger for mine. I use it for rimfire and shooting suppressed.
It can and usually will. More POI vs. group size. But you are correct as it's much like adding a tuner to your barrel. There are several options for mounting the Magnetospeed to your chassis instead of the barrel. Which should not effect group size or POI. I use a similar setup and have no POI change.
You guys know you can plug the Labradar and track all shots at all distances. You could use it to see what happened to the weird low speed reading. Like sometime you see the bullet speed going normally slower on the graph compare to other shots and out of nowhere a huge speed drop, which mean the bullet might have hit something in flight, or inconsistent BC due to a scalp on the loading ramp etc. Wich result in a difference in speed calculation made by the lab itself. So when you get weird data, just plug the lab to see if something happen :P
well its not very accurate and the range it can track the tiny 22lr is way shorter than 6mm up centerfire projectiles. my guess is that bad shot would have been lost after 25yd. Most 22lr will track maybe 50yd. It's BC cal can only ve as accurate as its accuracy % and that rating as distance increases. It does not actually take a mv reading. It's computed from a 20 yd reading. No way it can ve super accurate like say a Oehler or CED tradition screen chrono. Anything that is going to need a custom drag model or less accura5e BC reading is never going to be single digit accurate when you add in the inherent accuracy of just logging a vel9city. but then using a estimated bc to work out the mv. The only reason it's so popular is setup. It's by far the easiest.... As an example take a .223. at the 1000yd F/tr even 600yds. It really needs single digit ES in your10 shot strings if you are going to hang with the 308 200-20x bullet loads. There is no way you could use either the labradar or magneto as their accuracy % is too low. You need at least a 99.8% bare minimum accuracy. That still may not be enough as you couldvhave a shot off by 4 fps that is now 13fps es fli0 it. Either way at 1k shooting 15 fps difference in vel will push you out of the 10 ring with a 90vld or like bullet. Same issue with your 22lr when you shoot 100 yds. At a Sub sonic 950-1000 fps mv with g1 bc of 0.172. a 15 fps variance is a 0.60" vertical alone. Then add in wind you could be 0.75 away from from group mean center. 9n a moa target that's a likely miss and on BR targets that's out of the circle and possibly the square. It's not like 8ts hard with 22LR. You can setup the screen chrono in your basement or garage and send a box thru the screens. That will get you the vel spread and the mean spread etc you will be dealing with. Then run a box or two to get the tuner tweaked. if your smart you will have a barrel length that brings your ammo choice clearly subsonic. Then insure its as thick in diameter as you can comfortably shoot. 21.5-22" is usually good. 1-16 to 1!14 tw rate. Try Lapua Center X or SK Match. Try to find different lots and shoot for groups but also SD/ES. Rim thickness and Ogive to base.. you can compute most consistent jump to lands and seating depth. Find a great lot buy as many bricks as you can. Vacuum seal it up with desiccant packs.
No kidding, this weekend I was going to upgrade my old Chrony. I couldn't decide which of these two---and the same day you put pout a video comparison. Crazy! Thanks for cutting down my research time. Q) Can the MS work with a pistol, if so, how much barrel is needed and how does it fasten. Thanks for the work here guys!
The MS can work with some handguns but you need a picatinny rail on the gun and the picatinny mount for the MS. I think for that, the LR would be the way to go.
I was happy to see they are consistent and not off by much. It would have been concerning if the data output between the two systems gave materially different values.
the issue is the magneto has an eaccuracy of 99.5%. The labradar who knows as it can ge all over the place. The traditional CED 2 has an accuracy 99.98% if e erythi g is setup accurately with good light or the ir tops. Take a 3000 fps 99.5% 15 fps so there is no way you could ever be able to accurately record single digit SD es numbers. The CED @99.98% is a mere 0.6 fps. Sorry but there is a reason the labs are using traditional screen chronos Oehler usually. CED actually give equal accuracy but nothing extra. Can not see, for ELR especially, how labradar or the magnetospeed could ever be accurate enough for tuning to single digit fps vel accuracy for SD ES readings. There is just no way.
Never tried with 22LR, but Labradar position is critical and non-forgiving for accurate reading unfortunately. I recommend a recoil trigger device, no more missed reading or problem with neighbour shooters.
Thanks for posting but looks like youtube failed to post it properly. What I seein my notifications is: “TubeDobs replied: "Wilfred Darr I saw your question before I went to the range today, so I bring my 22LR rifle to try it and the device I use (I use the RAT) did not pick up any shot, looks like it is not sensitive ..." Thanks for taking the time to clarify that for me.
@@wilfdarr Yes, probably a bug or something... I will try again next weekend, I used my sensor device the same way I use it on big calibre and when back home I discover that the manufacturer say for small calibre, different positions of the sensor on the rifle need be tried and should be able to find one that work.

Just the video i was looking for regarding some vital information ive been searching for a couple of months now with little success...Many Thanks!!!😆

I’m still using a shooting chrony from the 90s. I’m new to the modern chronographs. Are you running the V3 or the sporter?
Hej Matt, great video 👍 which ballistic profile(G1,G7, RA4) is best to use in Strelok Pro for rimfire. Also what BC do you enter for SK RIFLE MATCH ammo.
Thanks. Regards from Ireland 🇮🇪
Would be interesting to compare these two higher end chronographs to the FX Chronograph for rimfire use.
Thanks guys . Great video . Answers a lot of questions .
What sensitivity setting did you use on the MagnetoSpeed? I could not get mine to read off of my rifle.
Can the MagnetoSpeeb be used with lead pellets and slugs ammunition?

So the Labrador needs another chronograph to set it up?
I thought a drawback to the magneto speed was if affects groupings?
While at the range about a year ago, I had my Labradar and a guy had his Magneto Speed. We were off about 4fps. Both are accurate, just need to set up the Labradar up correctly. I have the trigger for mine. I use it for rimfire and shooting suppressed.
Does the Magnetospeed affect the group spread? (It’s hanging off the end of the barrel after all)

Those are the CRPS staff shirts? They're pretty sweet!
Yes, they are, thanks!
For us poor people you should do a compare of old Chrono(light sensor) to new fangled magnetospeed, or labradar

Also a video suggestion would be spotting scopes--what you choose and why
My Labradar consistently reads 5-6 fps slower than the Magnetospeed with centerfire. With rimfire, the Labradar reads about 3fps slower.
I was happy to see they are consistent and not off by much. It would have been concerning if the data output between the two systems gave materially different values.

Is there enough recoil on a 22 to trigger it?
