Re: Need a good starting point for 300 WSM
I've had the best results w/ R22 and H4831.
My pets loads are:
66.5 Grns of R22 under 180 NBTs for 2940 fps MV
70.0 Grns of H4831 under 150 grain Nosler Accubonds (Haven't Chronied this one)
Both loads shoot .5-.75 @ 100.
I have a pretty fast barrel so you may not get 2900+ w/ the load I mentioned. It's a pretty mild load compared to the data I've seen.
165 Grn Speer Hot Cores also shot well w/ R22 (Don't have the notes but, I believe it was 68 grains)
All of those loads are fairly mild.
