I have a .444 marlin I reload for. I was loading up a bunch of Ranch Dog .432 bullets and couldn't seat any of them without shearing part of the meplat. There seems to be a slight indentation on the seater. This looks to be designed for round bullets or at least narrow nosed semiwadcutters. I'm thinking of grinding the edges or cup rim from the seater. I guess my question is, would a flat seater work alright with the Ranch Dog bullet?
