I went through a BFR stage. My brother got a 475, and i got a 454. I've shot a 45-70 many times. Believe me, if you are lugging one of these, the last thing you want to think about is lugging a carbine. That is essentially what it is! The lower power trap door loads don't boom as much as a Casull, but the higher you load, the more it goes boom! They are not practical, but more associated and appropriate for targeting, and hunting. I shot a doe at 119 yards one year with very little trying. The gun is scoped and had poor iron sights at least for me. Sizing is different than for a rifle (for cast), and the powder choices will be different. We found better accuracy with high end 332, Rel. 7 and H4198 with the rifles, but not so with the BFR. 4759 with lower to moderate loads were the best loads for this pistol. 10 inch barrel better for the powders than the shorter 7.5 inch. I prefer 2400 for lower to moderate loads in the rifle. Nothing could be assumed between one and the other. The Casull was more portable, but still a very large gun. I'd gladly get rid of it for a like quality single action 45 colt, but there is no such thing I can afford. Ill hold onto mine. I don't enjoy higher pressure shooting, and in fact shoot mostly slightly higher end 45 colt stuff nowdays. They work just as well without having to lug all that artillery.
