If you use reamers, the one from Sinclair can't be over done as it has a set shoulder that stops at a certain depth. They are carbide and last probably about forever. I don't use it for removing crimps because it leaves a very sharp edge with no taper lead in. The rcbs deburring tool works well but can over cut.
I have been collecting range pick up brass for 50+ years so I now have two wood crates 2'x2'x4' full of brass and no onger have to mess with crimped primer pockets.
