I'm fairly new to reloading and I have some questions about sizing brass. I know the .30-378 is considered a "free-bore" caliber. I've been reading alot about using bushing style dies and I want to try it out. My question is: Does this caliber work better to neck size or use a full length sizer? Do I need to bump the shoulder back? I got a new bbl for my gun and I now want to make sure I feed it the highest quality reloads I can produce. What do you guys think?
