These two are my favorites with the 143( and 145hht). The h4831sc is super consistent but slower. I have taken h4350 to 59 with no pressure signs at 3080 but shoot it at 3030 bc it works. I am shooting a 20" 7 saum Gunwerks.
Forgot to mention this is out of a SA. If I remember correctly I was loading at 2.850 COAL even though I can take them out past 2.950. They seem to like a little more jump in my rifles.
You could drop to the 140 absolute and get 3250 from the 4350 range, but 4350, rl 16, 17 oughta be good. H4831 might be a hair slow, I don't know of anything good that falls in that slot, vv560? It's going to be a blast regardless. I'm overdue for some hammer time with my saum, I've got about 75 140s to cook off. Might need to go thin the soup can flock this weekend.
