300 WM--- Best Velocity for Accuracy?

For all you guys shooting a 300 WM. At what velocity do you seem to get your best accuracy? I am shooting a 200 Grn Accubond and 208 Amax. At first I was trying to get the fastest velocity with no pressure signs, but I am learning that this may not be the best for accuracy. I will be using this for hunting purposes.

    For my savage 300 win with 200smk's and 26" barrel I found the best combination of velocity and accuracy at 2850fps .
    I was using imr 7828ssc.

    With a 26" T/C Encore Barrel and 200 Gn TSX I found the best accuracy to be at 2880 fps.

    178gr Amax 75gr RL22 3028fps .5moa
    180gr NAB 82gr H1000 3050fps .5moa
    180gr Scirocco 74.5gr RL22 3175fps .5moa
    208gr Amax 70.5gr H4831sc 2880fps .5moa

    I don't load for speed just sometimes I get it sometimes I don't.
    I just noticed my velocities seem to be on the high end... I treat my barrels with Gun Juice, maybe thats why, I don't know but there are no pressure sings in my rifle at these velocities but there may be in your rifle. Start 10% less charge and work up.

    Ivo, do you get a cruching sound using 82 grs of H-1000? I use 80grs and it's a full case load with slight crushing of the powder with 180 gr Scirocos

    IVO,
    Looks like your velocities are appropriate.
    I shoot the 200's at 2850 and the 180's at 3100.
