I posted about the Tubbs Final Finish months ago and finally got around to firing lapping 2 days ago. The barrel is slick as a whistle, but none of my former load will "hit the backside of a barn". The rifle is a 243 Savage model 11, 9 1/4 twist, 22" . The funny thing is that the last 5 rounds of the final polishing bullets shot a group just under .5 MOA @100 yds. I thought this is great! The bullets in the kit are 107 gr Sierra match which I assume are used because of a long surface bearing for greater fire lapping. In theory the 9.25 twist should never have stabilized the 107gr to start with. Anyone got any suggestion on loads or as to what has happened to the barrel. My former loads were the 95 gr BT's and the 105 Amax. Help needed!!!!!
