So, I bought a used savage rifle in .17HM2 a while back. I love the rifle, but it was splitting the brass on a regular basis, requiring me to pry it out. The rifle went back to Savage. Long story short, a few months later I wound up with a brand new rifle. It's great, an upgrade of the original rifle, accutrigger and all. Problem is, I keep getting split brass lodged in the gun. It's no longer in the same relation to the firing pin strike, so I know the chamber on this gun is OK. I've only used CCI ammo because it's the only thing I can get and I know that they manufacture the ammo for other companies. Anyone else had this experience?
