The 150's are kind of light for subs. My choice would be the 208's.
My 300BLK 's are a bolt gun and a single shot. The single shot is a fun gun. Have used it for hunting only so never used any heavy bullet.
If if did not shoot so good with the Barnes 110's,I would have the freebore lengthened and shoot the 220SMK's at 950. --- SAWMAN
