    The load I am shooting now is 78 gr IMR 4831 at 3221 fps. That is out of a 24.5" barrel. RL 22 may top that velocity, though.

    Upwards of 80 gr RL 22 or 85 grs of RL 25 may be the speediest ticket.

    i use 71 or 72 grains of i-4350; lapua brass and either a 215 or a wlrm primer. if you want more velocity a max load of h-4831 or a max load of re-22.
