I just got done checking out the thread about making your own blackpowder and it got me thinking. If things got to where you couldn't buy smokeless, could I keep on shooting blackpowder. I have a muzzleloader, but I also have a 45-70 a 30-30 and a 357. They were all originally blackpowder cartridges, well the 38 special was. I expect the 45 and 30 would perform pretty well, but I am wondering what kind of performance you could expect from the 357. I am thinking that it would get in the 800 to 1000fps range. Has anyone played around with blackpowder in the 357?
