i had 58.5 grains imr 4350. at 100 yards got 5 inch group. loaded couple different last night. 60.0 grains of same powder brought it into 1 inch group. lower the vharge the worse it gets. the 60.3 gets little wild also. i figure that 60.0 will be the load for this rifle. thanks

    I use 59.0 grains of IMR 4350 with 130 grain Hornady SST at 100 yards the group is consistently under one inch. Still tweaking with different bullets but I won't mess with the 59 grains anything else and it gets finicky.

    It has been my experience that WSM's and WSSM's seem to perform better on the high end of the spectrum.

    What's your gun?
    I've gotten an inch with Varget, but I have some 4350 in the bin, so I'd like to try it in my Model 70.
