    Hi all, my career in reloading has been quite short, i have a Remmy Sendero in .300WinMag, some of you helped my with the reload i have produced thus far. I am using 190gr Berger VLD's, 75gn's of AR2217 (H-1000) and seating them .020" off the lands which give me an AOL of 2.895, Average M.V. is 2714fps, and i'm getting .247MOA, i am gonna try 79.5gn and 80.5gn on my next outing, but after already trying 79gn i'm not sure if it will work ??? Should i try a different powder ?

    Cheers boys....keep up the good work. gun)

    .25MOA,
    I tried the 190gn SMK with H1000/CCI 250, OAL 2.9090" (.010" off).

    79.0gn 3078fps .142"
    79.5gn 3112fps .522"
    80.0gn 3148fps .496"
    80.5gn (no vel.) .419" was getting too dark for chrono

    I tried 80.5gn again four days later and velocity averaged 3145fps and accuracy was .5245 for a five shot group.

    When I bounced this last group's velocity off the week's before something didn't seem right. Not sure if my chrono was reading fast (not fully opened) that first day or what. I haven't been able to verify because I'm currently out of 190gn SMK's. Either way, I would think your velocity would be higher than what you 're getting. Kinda mysterious. JohnnyK.

    I tried 79gn AR2217 (H-1000) and got avg. 2909fps.....2 shots touching, the others of the group wide and high about 1.5" ?? But i think i had reserved myself to the fact that 75gn was my load after the earlier shots, i will try 79.5 and 80.5gn next.....if accuracy suffers what is another powder to try ?

    Why bother?

    Run a ballistics table for the load you have and ask yourself what you stand to gain from more MV based on your hunting and shooting requirements.

    It sounds like you have a good load there.

    Man, I have to agree. I would be perfectly happy right there. Sounds like you are really stacking them in there.

    Im pushing the 185g VLD at 3030 with H1000. If you mess with the charge weight your going to most likley adjust the seating depth as well and rework the load.
