We have a real horsepower race going! Personally, although I have a 454 RB, I tend to favor the 445 Super Mag. I could be tempted by an RB in 44 Mag. That ought to be a real tame cat by the new strandards.
I've heard that the BFR SA is now chambered for the Marlin 450 cartridge. Anybody have any idea of what that churns up in a revolver?
