Shooting the 32 Barrel Machinegun

We shoot a home-made machinegun with 32 barrels, about .36 caliber. We only had .31 caliber lead bullets so we used them, and our muzzle velocity was much less than it would have been had we had correct ammo. This is of course a scale model weapon based on, well, I’m not sure, maybe one of those Russian WWII rocket launchers. We use black powder only, and follow all proper safety precautions.
