Nope. Wasnt joking about running it in 1911s. Some of them put in a lighter recoil spring, but thats the only changes they make. I wont be running it in mine tho, as its a Rem. Rand, and I dont want to risk any troubles.
I am not sure what the velocity would be, but black powder is still very formidable.
The Colt Walker was running around 1000-1200 fps, but it was basically a mini rifle powder charge wise. I have fired 60gr of powder out of mine, but wont anymore. I normally run 45gr of powder, and its still quite a wallop. I would not hesitate to shoot a deer with it, were it legal here.
I load some of my 45Colts with a 150 gr bullet, and a full case of 3F, and they will go over 1000fps. I would guess the 45acp would still be doing 700-800 fps with the right bullet. One of these days I need to break out the chrony and get "official" speeds out of my other black powder cartridges, ie. 357, 38Spec, 30-30.
Painless, 30-06 designed for black powder?? The 30-30 was designed for smokeless powder 11-12 years earlier, in 1894-1895. Smokeless powder was abundant. I dont think the military was looking to go back to blackpowder in the 30-06. Most of the other countries around the world were also in the smokeless arms race, trying to get away from blackpowder. I wouldnt think we were looking to stick with black.
