I sorted a pile of Aguila ammo to try to get better, or at least more consistent, groups. I sorted it by weight, by rim thickness, and sub-sorted it by both weight and then rim thickness. It may have worked, but it didn't work well enough for me to spend the time/effort to do any more sorting of .22 LR ammo. I prefer to spend a little more money on medium or higher grade .22 LR ammo then the time and effort to sort lower grade .22 LR ammo.
I do sort .22 Magnum ammo by rim thickness because there isn't any match grade .22 Magnum ammo on the market. I'm happy enough with the 17 HMR and 17 HM2 ammo performance without feeling any need to sort it either by weight or rim thickness.
Other folks may have had better outcomes than I did, but my experience showed that, for me, sorting wasn't worth the time and effort when better .22 LR ammo was widely available and easy to come by.
