Thread: A few 308 questions.

trailboss is too easy with the cast 151s too somewhere around 6-7-8grns will be subsonic,but for me i WOULD if doing it again...would semi fill case EG more powder to base of neck so its something supersonic and use them for the first round....
those 150grn speers will go good too...I would pick load on similar % level to what you using..so 2??grns below book max...I would be surprised if they pattern much outside your other load if at all....
