Who sorts their rim fire rounds by rim thickness, and or cartridge weight? Have you found that it pays off in better grouping? Or is it just a way to pass the time between reloading sessions and trips to the range? If you do measure rims, what gague do you use? After 50 plus years of sending .22's down range, I'm wondering if I missed something!
i recently acquired a .22 Savage fvt heavy bbl ... I never heard of measuring .22's for consistency/accuracy ... but, you've got my attention ...
Thanks for that suggestion on Paco Kelly, his tools look interesting. Bumping up the bullet diameter would probably not hurt in my Ruger convertible .22/.22 mag.
I found a Stoney Point, now Hornady, rim thickness gague on E-bay for $20, so I'll be trying that one out first, but I'll keep Kelly's tool in mind too. I'll try and remember to post what changes I find after sorting out some ammo. Thanks again.
For serious target shooter the length and weight get measured some also measure the rim. Yes it does make a difference. Get a bulk box of 500 whatever spend a few hours in front of the tube and measure and sort them. Then shoot the same weight ones together and you do get less fliers.
Well, I got the rim thickness gague, and checked 50 rounds taken from a Remington 550 bulk pack. So far I am surprised by the consistency of the rims. 6 measure between .035 and .036 inches, 36 between .037 and .038 inches, and 8 ran between .039 and .040 inches. It will be interesting to see which thickness groups better, but that will have to wait a few days.
bump, whats the word on this is it working better for people?
