Black powder is somewhat safer than smokeless powder I'd say cause of lower peak pressure, but it takes up about 3-5x more space in a cartridge case so autoloaders tend to suffer unless they have either a wide range of power versatility like shotguns and are versatile with the types of loads they accept. Firearms that are designed for lower velocities tend to work best (Shotguns and Pistols/PCCs, maybe some heavy hitting rifles if your very lucky)

Typically heres how it goes Direct Blowback: 50-100rds before issues (maybe more, not much info on this) Inertia Operated: 10-30rds before issues (depends a lot on the time the operating system keeps the breech closed, the longer the better) Gas operated: 2-5rds before issues
