46 grains of H4350 under the 120 grain Speer.
This load shoots better than I can hold in my Rem M7SS. I did manage a couple 1/2" groups with my Leupold Vari-X III 3.5-10x40 tryout scope on-board, but there is no way I'd leave that large of a scope on such a sweet little rifle.
The powders listed in the first post sound a bit too fast for this caliber. I use 4350 for 120 grain bullets and 4831 or slower for 140 grainers. I have been told that Rel22 is an excellent powder in this cartridge, but haven't tried it yet. Hodgdon has a captive audience in me right now due to the "Extreme" thing.
