I have decided to build a new extended long range rig, Decided on either the 375 or 408 Chey Tac, and have to ask, that 408's a pretty big bore, and a pretty long OAL so do I need one of the presses set up for 50BMG to load them? Also, can I get a set of hand dies like I use for 308 to fit the Chey Tacs?
