H4831SC for the 7 SAUM is definitely worth a serious look. I run 60.3 grains H4831SC, FED215M primers, Norma brass, Berger 175 EH's at 2960ish FPS (don't have the exact velocity as I'm sending this) .010" jump to the lands. Single digit ES and groups exceptionally well out of my 26" Benchmark Varmint/Sendero contour chambered by Clay Spencer. I worked up a little higher on charge and didn't hit pressure signs but settled on this load based on speed I was looking for, accuracy and low ES. I'll be giving RL23 and RL26 a shot just to see what it does at some point but I'll be hard pressed to come up with anything better than the load I have now. Gathering parts for another 7 SAUM right now and I'll absolutely be trying H4831SC in it.
