Hi and thank you for the reply. I am using CCI AR Tactical Copper Plated Round Nose .22LR with no problems. The other ammo I have is Federal Premium Target .22LR Gold Medal. The Federal ammo sometimes does not fire I have also had a problem with it not feeding properly from the 10 round magazine as well as a Ruger BX-25 magazine. I have had the same problem with Ruger Mark IV either not feeding properly or not firing at all. The problems seem to occur about every 4th or 5th shot.Specifically, which CCI ammo are you using and what other brands are you talking about. I've owned a dozen or so of these guns and used them extensively in competitions. I can offer some good things to try/do to get them to function reliably. I will tell you that it isn't all about the ammo, but about gun care also.
Doesn't matter, the gentleman that mentioned the longer magazines not doing well in 10/22s is right. Stick with the 10 rounders and just get more of them if you're not going to keep it clean everytime. The longer magazines don't feed the rounds up into the chamber the same way as the 10 rounders do and there can be a number of problems with them.Thanks for all the recommendations. I usually give my guns a good cleaning after I shoot but every now and then I get a little lazy. Shame on me
