Would "modern" weapons work with black powder ? Let's

Rust... About it. Clean it good afterwards and you'll be fine. BP is far easier on guns.

smoke

Lower velocity to projectiles
More smoke
More fouling and potential for corrosion if not cleaned properly
Less effective gaspressure if gas-operated mechanism
>nothing critical

Depends what you mean by modern? Semi handguns would be hit and miss but a revolver and any repeating and even semi long guns would function with cleaning.

Black powder works just fine in modern guns, for a while. Depending on gun that might be maybe just dozen shots or less in worst case. After fouling causes malfunctions the gun just need good cleaning and it is good to go again for some time.

Most levergats were designed with black powder cartridges in mind. Any manually cycled gun will work pretty much without a hitch, be them revolvers, shotguns, leverguns, or bolt actions. Semiautomatics would be more meh, since smokeless has more umph, gas operated recoil systems may not cycle properly, in fact, most probably won't due to the lower pressures and the fact that black powder cases much more fouling and buildup.

Also, more smoke, lots of it. Lower velocities. Clean guns more often and more thoroughly.

You can buy black powder loads for some cartridges and try them out if you want, .45-70 comes to mind. I've shot BP .45-70 through my levergat

Velocity shouldn't be that much less for <2000 FPS cartridges

Of course, you might not be able to get enough black in the cartridge to get the same velocity as smokeless with many cartridges as they were designed for less smokeless in mind. But a shotgun shell shouldn't be any different.

>load all your ammo for your CC with black powder
>in a defense scenario you get the additional benefit of a smokescreen to obscure your position

Should work fine (for a while) but expect a shitton of rust and smoke

What are you using for primers?

If you plan on time-travelling or SHTF you need to realize that simply filling up the case with black powder won't do anything. You need a shock-sensitive primer.
