Fullsizing new brass
I getting started reloading, doing a lot of reading. I read in the "ABC's of Reloading" book that even new brass should be full-length resized. Is that so, and if so, why? I had planned on only neck-resizing.
I'm going to use new Winchester brass, in .270 and 7mm-08. Rockchucker master kit.
Thanks
