[quote=“Random_dragon, post:47, topic:10127”]So if you were insane enough, you could load a semi-auto with blackpowder handloads?
…I might be in favor of adding this for .22 LR and other rounds that existed back before the advent of smokeless powder.[/quote]
I’m led to believe that in semi-autos they’d have a problem cycling. The recoil pulse would both be really different and insufficient energy wise, enough to mess with how the springs work, plus it’ll clog up in short order. In a pinch you could “rack it for each shot” though.
But revolvers, bolt-actions, break-opens, pumpguns, leverguns and anything you cycle manually should work without issue. You’d just have to be sure to clean them quickly afterward and often.
One possible issue though: a lot of modern cartridges don’t have enough case capacity to get enough blackpowder in there to work right. Things like 9mm, 40 S&W, 45 ACP you could use with blackpowder but the power will be down. Something like 10mm has a fair amount of case capacity and wouldn’t be crippled quite as bad. Same with modern rifle rounds, the energy loss in 5.56mm would render anything firing it into a popgun by comparsion. It’d still be lethal as high velocity lead can be, but have nowhere near the same power level or armor penetration.
Big straight-wall cartridges like the .357, .44, shotgun shells and .45-70 (which was originally designed with blackpowder in mind) would work great. They’ll be down on power of course but still very effective.
I like the idea of adding another tier of ammunition, now that smokeless powder is uncraftable. Since anyone can craft it with time and effort maybe we could add a tier of blackpowder ammo. It’d be worse then even handloaded ammunition performance wise along with having a chance of damaging the weapon firing it, but if your a dedicated gunner/innawoods character it can help keep you shooting.
