Hello All!
First off I'm new to this forum and I've tried to search for info on this and haven't been able to find anything on this subject.
I put around a 100 rounds of SK standard plus through my brand new CZ 457 Varmint MTR. When I cleaned it I got quite a bit of brass filings on my pads. I also noticed some in the receiver. My spent casings have a scratch down the one side.
The gun shoots flawlessly and shot a 5 shot group at 50 yards that you could have covered with a nickel . Unfortunately it wasn't me who shot that group lol
My question is, is this normal and should I be concerned?
