So it seems that i'm ocassionally experiencing an ocassional stuck case in my chamber that won't eject. It's seems to be most prevalent with my win brass reloads, however i've been recently observing a few with my Privi blue box factory ammo. Dosen't seem to be an over pressure situation because i'm experiencing this even with conservitive charged casings. Do you guys polish the neck after chamfering ? I feel a slight lip on the mouth of the casing and thus far did nothing aboiut it. My most recent 20 ct run I took some fine emery and polished the neck. Shot this ammo and didn't have any issues. My rem700 .308 is fairly new with about 200 rounds fired thus far. Do new rifles sometimes have this issue ? Thanks in advance for the input .
