The snubnose pistol referred to is probably the Thunder 5 in 45-70.
Besides the BFR there is also the Sidewinder, essentially the same pistol, cheaper though.
The recoil isn't that bad. The short barrel (as in shorter than rifle length, allowing less propellent to burn/pressure to build up) and heavy weight make it tolerable. It is significant though. Cor-bon makes special 45-70 hunting loads designed for short barrels like the Contender that have propellants that are more efficient in the short space.
Buffalo Bore also makes some wicked powerful rounds.
Nothing I can't handle with both hands and 45-70 Marlins don't bother me at all unless they are really heavy loads.
Swindle1984, you may want to reconsider the Casull. While the revolvers are the highest quality, incredibly accurate, full house .454 loads are really painfull to shoot in it. Most people prefer the Taurus pistol instead, it's much more comfortable. I am still trying to get a .454 Casull myself, but it's going to have the .45ACP, .45WM, and .45LC cylinders as well. Shooting .454 full house loads will be rare for me.
I know at least 4 people up here that have them, a few more that I don't know personally, but this is Alaska after all.
All right, think you're all man enough? Try the Alaska Survival model of Derringer chambered for .45LC and .45-70! I've only seen one shot once, the guy was a hardcore type who runs a gunstore and has shot pretty much everything, and after the one shot would never ever shoot .45-70 in it again.
