Re: Any experience with loading subsonic .308?
I've been succesfuly using 9.4 of trailboss with 175 sierras an also 180 gr round nose. Pretty much depends on ur alltitude an where they go sonic at, so you'll need to chrono em an play with em from there. Also ur barrel length etc will effect em, so just play with em and see. I use magnum primers also. Some drill out primer hole but I haven't yet an been okay. Lots of good topics an discusion on it on here though. Mine seem to be running right at 1030 fps.
