If this has been beat to death I apologize but I am very frustrated trying to get brass for my 7mmWSM and 300SAUM.
For the 7 WSM, I'd gone to forming it from 300 WSM even before the brass shortage due to the poor quality of WW 7 WSM brass. Just neck down the 300 WSM to get a crush fit and you're good to go. 300 WSM is available.
