Ever wonder why you need a lathe?
I have some 445 super mag brass I need to trim about a 1/4 inch off of. That would be a nightmare by hand.
Chamber pound cast, trimmed case, I trimmed case. Lots of metal to be removed.
Take some 6061 aluminum, cut 3 chunks 1" long, face both ends, drill and countersink for cap screws. Bore them to a snug fit on a 445 case. Rim indexes off the rear of the soft jaws. Case is held very well with no chance of crushing the case.
With a very sharp cutter the brass comes off in little sprials. Cases are pretty consistant in length but I left them long enough to finish up in my regular trimmer. Each case takes less than a minute including time to get into the chuck. No way my trimmer, even with a drill, is going to beat that. This also leaves no burrs on the case mouth.
