How's the muzzle blast from that .45 with hot loads? Can you get shot loads over the counter in .45 Colt?
Muzzle blast, to me, is irrelevant in a defense situation. By the same token, a .452 250-gr. SWC at 1000 fps is not nearly as bad as a .44 mag or really heavy-loaded .45 Colts (usable only in the old Rugers). I use a suitable charge of Unique to get the bullet moving quicker than 2400 or H110, which would probably be better for longer barrels.
As far as weight is concerned, the Mountain Guns in .45 Colt are lighter than .357 or .44 mags with their standard barrels. I don't pack a box full of cartridges, just enough for emergencies.
And yes, commercial .45 Colt shot cartridges are available. Here's what I use; these throw out 1/3 oz. of #9 shot. I used to handload pistol shotshells using copper gas checks as under- and over-wads, but since I use them so rarely, it just makes sense to buy some now and then.
