I had a 308 Baer benchrest competition rifle, and made a hunting rifle with the same reamer so I could use my old match brass for hunting. I have shot a lot of game with it and really like the round.
As noted, there are many versions of the 300 Wby improved case. I did a lot of research over 10 years ago, and the 308 Baer seemed to be the best design out there.
