I need help too. I have a friend who is very happy with the 168 gr Bergers in his 7mm Remginton Mag. I intent to set up for those and 160 Accubonds for elk.
4831 is not going to produce the velocity conducive to long range hunting. It is a single base powder of WWI vintage technology. Yawn. I shot up 12 pounds. It came in a plastic bag inside of a cardboard box. I bought it surplus from Hodgdon's original stock. I'll take up archery before I go back to that stuff.
H-4831sc, will not get the 168 VLD over 2900 for me, but it has my 162 A-Max's moving at 3020FPS and is extremly accurate with 64 grains and no pressure. However Acurracy falls off if I go any higher. I have taken that load to 780 yards and it holds the accuracy out of my 7WSM. I have taken several antelope with that load.
I am shooting 64g of 4831 SC in my 7WSM. I went with the 168 Berger Hunting Hybrids. They have shot great and are much easier to work up. Velocity is at 2950 and I am getting 1/2 or less MOA. The BC difference is very samll, I think it is .617 versus .604 and take much less time and effort to develope. I got the load information from Berger and their recommendation was a max load of 64.8g of powder. The best result for me was 64g. If I went towards 65 the groups widened. I am loading them at the lands. By the way, I am shooting at about 700 feet above sea level. Dense humid air.
