Thread: Down loading 243 win to 6x45 velocities

I loaded up some very reduced 308 loads this afternoon, a bit different from my usual mild loads using 30-30 projectiles.
151gr cast bullets with 14gr of Trailboss, does 1565fps in my longer barreled rifle, I don't know yet what speed from the shorty. The shorty need half a grain more at subsonic speeds.
