Wolfgang's (and others) previous 44 mag posts say it all! Do a search, very informative. ( I admire his resolve in trying to get this barrel to work)
I often hunt with a Super Blackhawk (44mag) and thought it would be a good idea to get a 44 barrel for my . 243 superlite frame. You know, same load for handgun and rifle. It seemed like a good idea until I started reading all the negative posts concerning the 44 barrels.
The oversize bore combined with the very slow rifling twist seems to be the problem. (The shooters with any luck at all were using .432 and larger sized bullets.) There is a big difference for us, at the end user level, between sorting a set up problem ( bullets, powders, primers, bedding, floating, correct combination of components, etc) and attempting to fix a design problem. We can't fix the bore diameter and twist. You can do a search for 44 mag posts and they might help you with your decision. I never tell anyone what to buy and I'm not saying don't buy one, just know in advance it might be a challenge to make it work.
I was sending my frame in for a standard contour .243 barrel and decided to get the .357 barrel instead of the 44. (I have a 357 handgun so I just switched gears a little.)
I really wanted the 44 barrel and it was difficult to turn down, but I didn't want to go on the "timeless voyage" trying to make it work.
Been there done that with other guns.(.243 superlite) - Don
