I was going to do a build in the 6.5 mag, but could not locate brass on a regular basis. Midway has a run once a year. If you don't get it then, you probably won't get it. On one occassion I found it on e-bay, but he wanted way too much for it. So he got to keep it! A .264 Win Mag is very close to the 6.5 mag. If you do not hot rod it you can get good throat life and brass is available from Midway and others.
