Dang it this thread has me thinking of a 30" light palma barrel. Either remage or shouldered short chamber. rent a reamer and have at it lol.
Running heavies was kind of an afterthought for this rifle unfortunetly. I have an unfired Bigjorn Origin with a 22" 1:10 Bartlien CF in a Rem Varmint contour in a Mesa Altitude stock I plan on using as light weight hunter right now. After Running some numbers, the heavies would 100% be the way to go though. Was kicking around HH's or BD2's but I like the way those heavy Bergers run in a 308.
