hello everyone, new here. just looking for some data. i have had great luck w/ alliant powder in other rifles.just bought this puppyin .330 win mag. accuracy and velocity wise, i always develop max. loads w/ the right bullet for the job. any help is appreciated. i suspect something alittle slower will achieve the near 3,400 fps i seek(rl 19 for example) but who nows.
