I shot it yesterday. It shot reasonably accurately with some older Remington ammo. Switched to CCI and every case split. This same ammo shot out of my Marlin HM2 doesn't split cases. Any idea what is causing this?
How did it shoot with the split-cased ammo? If it shoots okay, just go with it and quit worrying about it. I've shot scads of HMR in my Marlin, some cases split, some didn't, but it shot them all just fine. Since I'm not going to reload them, I don't care about it. I just use it happily.
