Hi All,
Shooting subs in a slow twist 308 can be tricky. At 11.25", my M24 "shouldnt" work with most heavy 30cal bullets. However, I got some 200 gr lapua subsonic bullets and through some trial and error found the sweet spot. The load is below as are photos taken from a 90 yard group.
Case: Once fired from Federal 175 match
Bullet: Lapua 308 subsonic (part: 4PL7060-Lapua )
Powder: Trailboss at 10.5 gr
OAL: 2.801"
Primer: Winchester
Velocity: 1000 fps
