I'm breaking in a 6.5 creedmoor I got from Cabela's and I'm getting a copper smear about an inch from the muzzle. There could be more-that's all I can see without a borescope. It's not a little copper-it's a good amount. It doesn't seem to be getting any better after 5 shots, cleaning to bare metal after every shot.
Any ideas or suggestions?
Thanks
Dan
