I used a Dillon to load most of my ammo, .223's, .308's, .44's, ,45LC, 45acp, 475's etc and it works great. I dont like the way it handles the larger caliber stuff I reload like .338/.378 weatherby or even the .450 Marlin. RCBS or LYMAN? I see some new stuff out with 4" clearence but I have limited experiance with a single stage.
