I have some Bertram Brass "BB" brass shells I bought at an estate sale that were loaded rounds. The headstamp says "45 Basic" and they are just short of 3.3 inches long. They were loaded with 500 grain paper patched bullets (boolits so I don't get lynched) and waxed card wads and coarse black powder. I would like to sell them but cannot with them containing powder. I have used a long screw chucked in a drill to remove the cards and dump the powder in a couple (literally 2) and I don't want to do it again. I think I have around 30 or 35 of these (I haven't counted) that I would like to get rid of. Any way of just firing these to unload them without buying a 2000 dollar weapon to do it?
