Thanks. Saw the note on Brian Enos site about using other manfucture dies. Seems the Dillon seats and crimps in separate dies, where most other manufacturers combine both operations in a single die. Ironically Lee has a crimp die that should work if I wanted to go that route, but never had an issue with RCBS's 338-06 die set.

I'm starting off with the 454 Casull in the Dillon 550, since that is what I need to reload now and follow it with the 338-06. Have a couple thousand rounds each of the other calibers (9mm, 45 ACP, .223 and .308), so have some runway until I need to buy those conversion kits.

Maybe I'll trade you back some of the Freedom Munitions 124gr 9mm ammo for some counseling/training once it comes in.
