My son is showing an interest in possibly trying cowboy action shooting. I'd probably try it as well. I like western guns but not a fan of dress up, which is the reason I haven't tried it before. We just picked up an Uberti 1866 carbine in 44-40. We've had a Marlin 1894 in 45 Colt for awhile that he's been plinking with but he's a bit of a crow, shiny things catch his eye so now we have the 1866 as well. My question is how important is it to have carbine and revolvers in the same chambering? I see the convenience factor but I'm guessing a lot of people might shoot different loads in each anyway. We're looking for a single action pistol (2 if he continues to be interested) and trying to decide if we should stick to 44-40 or if 45 Colt is ok if we find a deal. I doubt we will ever be hardcore maybe 2-3 matches a season. I'm set up to reload both 44-40 and 45 colt. In a perfect world I'd go 38/357 for cost but my son likes things to be historically accurate as well. I should have never let him watch Hell on Wheels lol.
