Get more Berger’s and dry fire a lot
Yeah, I have to say that just having another 130 grain bullet might not do it...I have had very good luck shooting Berger bullets, not so much so with most others. Didn't used to be that way. I could shoot just about any bullet made in my rifles and if the rifle was accurate the bullets, no matter what brand {within reason} did their job. But that is not necessarily true these days. Berger bullets seem to be more accurate when others wont shoot.
