Iceman,
A few years back I worked on the 6BR for silhouette. The rifle was built on an XP-100 action with a 26", 8-twist barrel. With 28 grains of N135 the 95-grain Berger VLD's were shooting way tighter than 1/4 MOA with a MV of about 2,800 fps. That had to be the best out-to-turkey rifle out there. But, cry at rams. The toughest bullet I found was the 105 Lapua Scenar. With 32 grains of N150 the 105's were going about 3,000 fps. On a well setup range you can expect to ring about 25% of the rams hit. If there is a headwind holding up the rams or they are bent or the stands not up to snuff there could be a lot of crying going on at the ram line.
