Hey everyone, I don't post on here much and its been a while since my last post but here it goes.

Before the recent mass shortages i ordered a 7mm-08 bbl from Jim and decided to wait on purchasing brass and such for components for it. Well the time is coming to start gathering everything else up but brass is rather difficult to locate for 7mm-08 at this time. A friend of mine just recently sold of a .308 and a .243 so i was thinking of getting his old brass from him to re-chamber into 7mm-08. out of the two choices which would you recommend, sizing up the .243 or necking down the .308? Thanks in advance for any advice.
