[QUOTE="Deleted member 46119, post: 1241403"] I've been working on my 375. My criteria are easy. I have a 12 twist barrel so limited to bullets that will fly with a 12 twist. I want to use a Weatherby Mark V action. So the case diameter and bolt face should approximate a 378Wby. Turns out the 500 Jeffery, same as used by SwampLord is perfect. The base is the same, the belt on the Wby is the same as the Jeffery. So.. The case design is a 500 Jeffery necked down to 375 with a 35° shoulder. Simple. Jamison and Bertram brass are plenty strong enough. SMK 375 350grain, 329 Hammer, Cutting Edge 325 Lazer, 330 MTH meet the bullet limits. Heavier would be better but I'd have to get a different barrel. I'm looking to source a "bench rest" style stock. Failing that I may go with a space frame. Either way it may wind up being "barrel block". I'ts nice to have a mill and lathe. [/QUOTE]
