I have 2 300 WSMs and 1 270 WSM, and used to have a 7mm WSM. I regret selling it, but I sold it to help pay for the wife’s college. Anyways. One 300 is a Tikka T3 Lite now loading issues, the other is Rem 700 that does experience issues from time to time. The 270 is a Win 70 and no issues from it. I hunt quite a bit with both of them, but never shot anything with the .300’s, 270 is a different story.

Yes, brass is hard to find at the moment and 270 WSM more so than 300 WSM. If you find it stock up. I will say this. I have quite a bit of Federal brass for the 270 WSM, primer pockets give after 3-4 firings, not so with the 300 WSM and Federal brass. I haven’t had this issue from Nosler and don’t have that many firings from the Remington brass I bought last year. Too bad it was a 2 bag limit.
