LOL, if you reload and use Lee's brass case tool to trim brass you can use it. Usually you just need the next bore size spindle on the trimmer. For example, if the bore is 30 cal, then use a 7mm/.284 spindle. Spindle will fit loose in bore, so you will need to shim it to take up slack, so it will not wobble. I use either aluminum from a coke or beer can, or brass shim stock....this will also protect rifling in bore. You can chuck the trimmer in a drill if you have a large enough drill. I don't, just spend 15-20 minutes hand turning the trimmer. Helps to apply lub to spindle and face of muzzle.
