If rebarrelling 7mmWSM would you go to 7-300wsm for brass ?

[QUOTE="BoatTail, post: 2389493, member: 74670"] The head space, shoulder angle, and length of the cases are all the same. The difference is when you neck down the 300 WSM you may have to turn the necks while the necking up the 270 it will be less likely. The reason for the possible neck turning is, when you neck down the 300 WSM, the neck is made slightly thicker as the brass has to flow somewhere. It may or may not be an issue with some rifles pending on the neck diameter of the chamber reamer used or the neck wall thickness original 300 WSM. My question is why go with the wildcat when the 7WSM Is available as a standard cartridge. Is it because it seems more accurate as it's closer to the SAUM versions, or is it just case availability?
