I just purchased a Remington 700 chambered in 270 wsm from a local gun shop. It was on the used rack and sporting a Mc Millan stock . Looked like new not even a scratch on the bolt face. Before I skim bed and work up a hand load I like to sight it in with factory fodder before I go any further so I can see how she acts before improvements are made. All I had was some Federal 130gn power shok. 2 boxes 2 different lots . 1 shot felt good went to eject and the bolt was locked up , now I didn’t have to beat it open but it was extremely tight. the case has ejector marks and slight ridge around primer other than that the brass looks fine . So I took one from the other lot same exact thing. I’ve never had this happen with factory ammo. I checked The chamber dimensions along with the free bore and everything seems spot on. The ammo was store bought from Wally World . This really stumps me. Maybe they load these that hot ? What’s your thoughts ?
