LET 'S SEE....IN 45COLT HUH....So far to load 45COLT cartridges the past 44 years I've used dies from CH, LYMAN An original die set sized to load .454"OD bullets, RCBS steel, RCBS CARBIDE, RCBS COWBOY, LEE, ECHO, and a couple of others that excape my memory now. ALL OF 'EM loaded perfectly good ammunition. I now use some of all those dies to load 45COLT ammunition BECAUSE this size die works best here, that expander works best with those bullets, that seater die works best here, that crimp die works best with this brass, and this one with that brass. LISTEN UP; never ever miss buying cheap used die sets you see in gun shows as sooner or later that die set will bail you out of a problem; ALWAYS buy used crimp dies in particular.
And so it goes...
