Just picked up a nice stainless Mini 30. My first range session went well,other than what appeared to be a few light primer strikes on the Golden Tiger steel ammo I was using. I have heard these guns dont like steel ammo. Is this the truth, or one of those Internet myths? I like the gun but with ammo availability being what it is I need to be able to run the cheap stuff. Any tips, tricks or advice from fellow Mini 30 owners would be appreciated!
