Criterion No.4 barrel testing

[Brian Dick]

corben1, I'm truly impressed with the barrel I fitted up too. It cleaned up easily. The bore diameter must be right considering the performance with both Mk.7z and Sierra Matchkings. There was a little bit of copper fouling but I did break it in with 20 rounds cleaning between each shot which should make things stay cleaner. I'll admit to not cleaning the barrel absolutely spotless of copper after every session and I was only using good old Hoppes No.9 on it. I was sort of replicating the use/maintenance an average shooter would give it just so gauge performance. I will give it a good copper cleaning when time permits. Glad to read you're getting in some range time. Good quality domestic mfg. L.E. barrels have been a long time coming!
