I went back to the range today. I put 12 rounds through the new barrel. The first one was a flyer which I kind of expected since I had just cleaned the barrel. The next 11 were just over 1 inch at 50 yards.
I took the rifle home and checked it out with the bore scope. The copper is back. I did the Brasso thing and some more Patch-Out. In fact it's setting in the work shop with the Patch-Out still setting in the barrel. I'll give it an hour and go back. I was shooting some 55 grain hollow points and this time it was with 23.2 grains of RL10x. The upper functioned perfectly and the brass was deposited at 4:00 in one pile. If I can get the copper thing figured out I think it will be a shooter.

At 100yds group will be even bigger... I mentioned in the past if one is going to buy a barrel get a green mtn barrel. I bought one 2yrs ago at the time they said they were lapped barrels. No longer say that. But for $198 you can’t go wrong.. I recently bought a Ballistic advantage barrel for my daughters AR. I must hit the jackpot with this barrel. It will hold the 10ring at 600yds with 77gr Sierra OTM’s.
