I have a 358 Win on an SB2 frame. It's about the most accurate rifle I've ever loaded for. Sadly I can't (I refuse) get a 358's full potential from this rifle. The action has
already loosened significantly. A 230g at 1825fps is about as hard as I dare.
The shotgun/muzzle loader/pistol caliber frames are SB1's & they are cast and far too weak for high pressure loads.
