You guys will have to wait for part 2 @ 100 yards 😆😆

While sorting, if you kept one of the heaviest and one of the lightest then shot just those two and do the same with rim thickness now that would be interesting. Great work.

Another great video. Thanks for all the effort you put into it.

I enjoy sorting the ammo, its surprising the how much each round may vary, I started using a spent .223 round and dropping a 22lr inside the 223 case, it fits perfectly, its a cheap way to start sorting 22 ammo using a caliper, I upgraded to a raven eye custom gauge and a digital dial indicator, it works great, I use the out of spec stuff to warm up the barrel and for plinking

That is so serious dedication to your craft, great 👍video

Definitely interesting results. Thanks Josh. Looking forward to 100yd follow up.

Awesome job Josh keep em coming

I always enjoy watching your videos. Long time ago I was a Marine sniper. I had a lot of range time. Think of a barrel change cause I shot it out using black tipped ammo to recover the brass for reloading in my 30 caliber. I have watched other videos by other shooters. By far you are the most accurate shooter on Utube. Your training shows in your targets. I am 74yrs old and have a brand new CZ 543 in my safe. I plan on putting range time then compete locally.

Thanks for the video matey. Saves me from having to do it myself.

Another awesome video Josh. I did try it once and had positive results also. Looking forward to the 100 yd results.

Great shooting as always Josh.

Thanks for another great vid. I wouldn't have thought that sorting would have had such difference in grouping.

Thank You Sir! I have seen SoCalPlinker sort bulk ammo and others with fair results. This test shows tightened groups! 👍🇺🇸 #22aday

Great job! Great content!

Definitely worth the time and effort imo 👍👍

Thanks for the video. Seems to be no end to how far down the rabbit hole one can get.

Can't beat your video's !

Thx for this Information

Enjoy the channel very much. I’m a benchrest shooter ( centerfire & rim) There are lots of videos of quality rimfire ammo being tested. But no one talks about action torque and how it affects accuracy. It applies to rimfire the same as in centerfire. Can change good groups into excellent groups with the same ammo. Would like to see video comparisons on that. Thanks

Great video and I half to say your intro is🔥🔥🔥🔥

Thanks for doing that. I recently sorted by rim thickness using the Hornady tool - easier than without. I saw a similar improvement. I shot sorted Center-X in the ABRA (benchrest) Ga state championship match this weekend and shot my best scores ever. I doubt that it will make a big difference in your game unless you’re just missing those steel targets. You do some fine shooting with minimal support!

Thanks good video and comparison

Great video!!! THANKS

Good video, thanks for doing it. In my opinion and experience, weighing the rounds is generally useless because you aren't weighing the individual components. Rim Gauging can be of use, except you missed one important part: the rim thickness is akin to headspace. Poor headspace in a particular chamber equals poor performance. Once you rim gauge the rounds, test each lot and you will quickly find that one particular size works best in your rifle. Keep up the good work!

I Love your concise to the point videos ie ( Always the best) 😃 That sorting and measuring rim thickness almost drove me to the psycho ward 🤯. But it is essential if you want to be competitive and win matches. I would consider letting a kid do the sorting to keep your sanity 👍🏻

I do the rim first and weight second. Works out the same. I've been using Eley Match. Definitely helps with flyers

Wow that sorted

That is insane. I've seen this done with bulk and yeah the results were startling but you don't expect variances that wide with top tier match ammo.

I weigh my amo with the exception of some Midas and find similar results to what you produced today. Plenty of people say its beyond the effort. Just depends weather the small amount of improvement is what your chasing.

Maybe you should try just weighting vs just measuring rim thickness? Keep up the informative vids, and good shooting. Jim

I used to shoot 3 position smallbore. My coach told me the only difference between grades of Eley is how fast the line runs during production. Cheaper ammo runs faster so less consistent. Except for the different bullet in the tenex it’s all basically the same. I’m sure it’s the same with Lapua and RWS, etc. With that in mind, sorting by weight would seem to be more productive with good ammo. There was one kid who spent the winter sorting cheap bulk ammo by rim thickness who had decent results. With quality ammo, weight just might be the way to go.

Excellent test! Cutting group size by 1/3..... I'd call that definitive- Interesting thought; what other changes could be made, to result in that much improvement? (When you're already dealing with a quality gun/ammunition, of course) Looking forward to watching the 100yd test next! Thanks!

Hey Josh. Another very helpful video. Thanks. Been meaning to ask what is that rear bag rest you use?

i'd like to see you shooting a bench rest target in 50 meters with a 25 targets for see what you can do ; other thing is bring another cz 457 mtr , shoots and compares by yours ; other thing is make a average in 5 targets but with 10 shoots , great videos my friend , i hope some day shoot like you , big respect .

Would like to see you shoot the ammo that got removed from the sorting. Just to see how much worse it gets.

Man you need the hornady rim gauge I love mine!

VERY INTERESTING, I'VE HEARD ABOUT THE DIFFERENCE WHEN THE AMMO IS WEIGHED AND RIM THICKNESS CHECK. SEEMS TO ME I DOES MAKE A DIFFERENCE, BUT THEN AGAIN I'M NOT TO SURPRISED SINCE CONSISTENCY IS THE NAME OF THE GAME.🤔😁👍

I have been experimenting with measuring rim thickness and weighing lately. I measure the rims by dropping them in a 2" long 1/8" brass pipe, then throwing my caliper on. The difference minus the two inches is your rim thickness. I have messed with several cheap ammo's. Aguila competition match and Federal Auto match being a couple. I found that if I take the weights in the main group area for that batch, and throw out the extreme highs and lows, I can turn those ammos into respectable groups and have put as many as 4 through the same hole at 50. Fliers are pretty much eliminated. If I use the throw aways for sighters it looks like a shotgun blast and you can see where all the fliers are. SD on my Labradar on the sorted is 12 or less consistently with 10 shot groups. SD's on the sighters run anywhere from 40 to 100. Its quite a bit of work but I am gaining knowledge so I enjoy it.

Good timing! My rim thickness guage and scale just arrived this morning. Measuring out CCI standard and pretty surprised at the variance…interested to see what a consistent round will do.

Two things. I don't use the ultra expensive ammo for shooting and expect some flyers. They're usually very obvious. When you consider what reloaders go through to enjoy their shooting, this type of sorting is very little work and you'll have lots of ammo for fouling shots after you're done. Its a win win. After cleaning you want to foul the rifle using the same ammo. Well now you'll have ammo for that too. I"m going to try that with my cheaper ammo. Wouldn't be surprised that's how the manufacturers to it anyway. If I can start with a brick of ammo thats A$8 per hundred and end up with several boxes of ammo that shoot like the stuff that costs $15 per 50 it would be worth it to me. That's without taking into account the almost wasted fouling shots. Can't wait for part two.

While you are testing you might want to ad Federal Premium Gold Medal Match to the list of things to try.

Do the same test with SK match PLEASE!!!

Hi Josh I just find your video on You Tube and really appreciate it ! I have a little question for you who make those black plastic transport ammo box that you have in this video who contain 2 rack of 50X Lapua center x rack what is the company or model Thanks keep on your good work Claude from Québec Canada 🇨🇦😎👍

The difference is 33% reduction, not trivial by any means! For comps, definitely worth the effort if you're trying to squeeze everything into a top finish.

Definitive! Very nice. So does the sorting make the rounds equal Midas + or X-Act? That would be a good head to head test. Sorted vs Midas +.

What do you torque your action screws too, and have you ever played around with these settings. Thanks.

Great video. What makes more difference? Weight sorting or rim thickness sorting?

Have you shot the Lapua Biathlon Extreme? If so, what’s you opinion? I have 4 boxes I’m going to be testing here soon in my CZ 457 MTR VPT

I rim sort then weigh. Doing centerX today. The match Eley has less variation in rim thinness but a little more weight variance. I use out of spec for warm up and sighters

Sort to perfection

Just the confidence it gives me is well worth the 4hrs it takes to sort a brick of 500. I found that it even helps with Eley Tenex & Match.

With all of the effort serious rimfire shooters go to matching their barrels headspace for the ammo they normally shoot have you ever looked to see what the variance may be in the shells overall length say in a couple of boxes both the same lot# and different lot #'s? That could have just as much influence as weight or rim thickness. Rather than putting forth the time and effort for every shell you fire perhaps doing enough to establish patterns with a brand and series of ammo would be more useful as to whether there was a point it made little difference to buy a higher grade or there was a drop off point where not to go below a certain grade within a brand of ammo. Way over my needs for my uses but I like learning everything I can by following you guys where it does matter and your testing results.

I weight sorted and sorted according to rim thickness and oal. The biggest gain I saw was in my rifle was rim thickness. I've recently started trying something else and it helps sd's immensely.

Now i'm curious to see how the Sorted Center-X stacks up against Unsorted X-act.

I do something similar with medium grade ammo. I will weigh 15 or 20 round together then divide by the number to get my average. I then keep ammo that is within .3 grs of the average. for instance if the average is 51.7 I will keep everything between 51.4 and 52.0 grs. I no longer worry about rim thickness. It just did not seem to make much difference. Sorting does not seem to help with cheap ammo. Winchester Wildcats are still Winchester Wildcats no matter what you do to them.

How are you sorting? Do you record weights for each round, then find the Standard Deviation of the masses, then eliminate all those that are outside of x Standard Deviations from mean? Then do the same method for rim thickness on the "good" weight rounds? I am curious. Would your batch of cull rounds end up producing good groups with shifted POI? In other words if you tested your high weight-thick rim culls, they should themselves group pretty good, and the light-thin culls might group well too. They just likely wouldn't group in the same spot on the target.

Enjoy all your Videos Josh..What was the rim thickness and bullet weight you selected for this video?

Sorting makes all ammo better!

I am not that dedicated. Interesting to see real world data that shows the difference it can make though.👍

What ammo container is that?

It's a shame you don't live around Birmingham, AL A friend of mine is the importer of Anschutz rifles and RWS ammo. He has a 100 yd indoor range. Your rifle is put in a fixture to test ammo. Takes the human factor out of groups.

Wipe the grease off too and don't rim gauge, LENGHT gauge the round from tip to bottom for the case. cheers

Bullets or catridges??

That rots, your shooting was great the Ammo should be a little better for what you pay for It. Isn't that why we buy lapua Ammo for its consistency

Sk why is it I am looking at a vudoo or center x

What happened to part 2? It’s gone or private

Can you give the address of the store where you can buy the orange targets you shoot at?

Interesting to note that your rate of fire was slower with the sorted ammo

Where you get those ammo boxes?

So, what specifications were you sorting these projectiles?

It also gives you confidence that any flyers are you . I do it with SK long range

Was that luji or match barrel that came with it.

You really should be shooting the ammo "blind" , even "double blind" for truly statistically meaningful results, to eliminate any +possible+ bias on the shooter's side of the equation. Still, interesting, I wonder what Papua would say, given that they show tighter groups on their "out of the box" ammo? Cheers, keep well!

That shows that the ammo is the cause of most of accuracy issues, providing all other variables are ruled out.

Maybe do it in reverse as well you may be practised by the second round.

I can’t find center x anywhere..

Your groups will never improve till you get yourself a decent rear bag. Noticed you hold stock with your left hand & also noted movement whilst shooting. Get yourself a stable platform first & then try & shoot groups. You will see a marked improvement. I regularly shoot 5 shot groups 50 yards up to .25. but shoot Eley Match ammo. My best is .06 but average .11 to .20.

Rip the heavy one and the lightweight bullit apart and weigh every component separately the diverent weight of the gunpowder is the biggest not the shell or the head

Should do it blind. Sort one batch, and don’t sort the other and get someone to hand you one batch without you knowing which is which. That would be a good test.

"measured the rim thickness with my micrometer" *shows video measuring with calipers*

Good video, good info, music sucks so i left.

try Midas my gun loves them. 457 Varmit MTR stock.

Ain’t going to do it.

The Dillion scale is not up to the task you were asking it to do! +/- .1 grain is NOT good enough to sort those bullets!

WOW! As an old BR-50 competitor I must say, nothing about this test , the groups the rifle or, the shooter impress me!

Wow, for the Money, Lapua Center X out of the box sucks. That was 3 fliers in 20 rounds. I am not sure the sorting did anything.

Sweet............... now stretch that puppy out !!

Waste of time
