What are the best tools for analyzing .22 ammo (i.e., concentricity, rim thickness, etc.)? Also, do they make an over-all-length gauge for measuring the amount of "jump" a particular brand of .22 may have in your gun? I know you can't control the seating depth in the ammo but I assume various ammo has various lengths. Thanks!

For rim thickness, the best I have seen is an empty .243 case. You measure the case, then place your .22 cartridge in, bullet first and measure again. The difference in the two measurements is your rim thickness.

Great idea, thanks!

Disclaimer: I have not used this method. I did find out that weighing cartridges did not improve accuracy of Wolf ME.

You did something to your ammo!! All yours went in the 10 ring sat!!

Xd - Did you not see the picture I posted of him talking to one of his rounds before chambering it? He gives them instructions on where to hit on the target before he chambers the round. Looks like it works.

There is 2 things that can improve accuracy for the rimfire.

1] Weight: Check your match ammo. Most of the weight differences is varying amounts of powder weight.

2] Bullet Diameter: Check the bullet diameter with calipers. You'll find it varies. You'll have some .224 .223 .222 .221 .220 with a surprise of less every now and the.

As with handloads consistency is key to accuracy.

Give it a try on a group, won't take that long to get 5 or 10 weight and diameter the same.

When going through the rimfires I always save the ones that measure .224 for the AR with the Ceiner.
