The Lee case trimming stuff is about as fool proof as you can get. I bought the new Lee Classic Cast Press. I haven't got but around a 100 rounds in it yet but I can't picture it wearing out. It was made with the 50BMG in mind. Yes it's heavy. Bolted to the bench, who cares about heavy? I like it. By eyeball i would say it has a longer throw than the rockchucker. Can you do 50BMG in the chucker? the method of spent primer disposal is very nice. My son doesn't reload. he's to busy using up your tax dollars. in a few years perhaps the grand kids will get into it.
