Thread: Barrel ?

Learned something from this Vid, was considering carbon ring problems, after all most of my shooting has been done with a Can on. Own a cheap bore scope, this guy had a muzzle entry / loaded empty case which made things real easy to see. Not a issue for me, but it proves I'm triming my cases Sammi spec, way to short. Interesting had proved this with a sliding ring set up on 223, but this shows it up really well. Lands are there but not sharp very worn / tapered, and a good clean would help. https://www.youtube.com/watch?v=j3hdAWVe05U&t=3s
