I’m starting to load some .310’s and looking to see what you guys all do to bring down the neck of the .405 brass without crushing them. I have a 378 GNR set, so that’s the first step down. I did a couple to .310 next and it is a long size down from .378. Even we’ll lubed brass I boggered up 2/6, so I stopped. Already talking to a couple people that say just neck size only till you fire form. could you use maybe a .357 pistol die to help in between the .378 and .310? I’m practicing on .405 brass before I try my limited supply of .310 brass. Thanks for any advice, Michael
