Thread: What in the world?

Ive been partial length resizing since first started rolling my own 25ish years ago....the "how to " and why is in my 1st edition nosler reloading manual.my poohseventy HATES neck sized ammo.....suspect bore is slightly off centre from chamber.... and full length resizing works brass heaps and had led to head seperation early on...so have stuck to partial sizing...when I got the .223 and .308 it got same treatment....the BLR wont chamber brass unless its been full length sized and some of it needs to go through an older 30/06 die aswell to squeaze the base in enough for it to chamber easily....which makes me suspect the hornady new dimension .308 dies have generous chamber sizing.
