I didn’t care for the longest time….if it went bang, I was happy….until I got my Custom Shop 10/22. Here are some of my test results. All are 10 rounds (one mag) at 25 yards from a rest. I have the best luck with CCI (except the “quiet” suppresser stuff) and the bulk Federal was good in the gun. Winchester will not even chamber in it! I stayed away from Aguila because I find it really dirty too. I guess you really have play and work to find what the gun likes…
