[QUOTE="jskmtd, post: 1791039, member: 19880"] So I have about 220 rounds down my 338 lapua ackley improved. 100 of those rounds was fire forming new brass to the ackley chamber. Last outing I was seeing pressure signs and my groups opened up to about 1 moa when it had been shooting in the .3's. I have been working on the chamber at the end of the brass with a bronze brush and bore tech carbon remover. The first picture is before the bronze brush the second picture is after the bronze brush. What do you guys think? Am I getting it or do I have more work to do? Any help would be appreciated. Thanks, Jon[ATTACH=full]165484[/ATTACH] [ATTACH=full]165485[/ATTACH] [/QUOTE]
