original chamber had tool marks allover, fired brass was almost impossible to cycle again, plus it was off-center with the bore, so I had it redone with the same caliber. Still I was getting vertical fliers, so I ordered CBI bull barrel from Jim. Today I tested my new barrel and best group was 0.2" and worst 0.5" and I haven't played with loads for it. Also I didn't load my good bullets(Berger or Scenar), for break in I had 100 grain Hornady Interlocks and they grouped 0.3" with factory barrel they shot 1" - 1.5", I also had 105 gr A-Max and I got best group using them, I did try 87 gr V-Max and they grouped 0.5"

here is 5 shot group it has one flier, I think it has to do with kids next to my bench banging those AK-47 with rapid fire...

it seems all my groups had one flier, I guess I have to work on load development for it and play with action screws, this was only break-in session...
