[QUOTE="Kevin Thomas, post: 374973, member: 15748"] KNC, For starters, you've got some powders listed here that aren't really suitable for this particular combination. The Varget is about right, but if you want to reserve it for the 308 Win, that's fine. Still, it is an option. Most of the other IMR and Hodgdon powders you've listed here are going to be too slow for this combination, particularly with the lighter (150 grain) bullets. IMR 3031 would probably be a decent choice for the 150s, but I haven't found data for this with the .311" bullets. Sierra lists this powder with a starting charge of 38.9 grains, and goes to a max of 44.4 grains, for about 2,700 fps. This data, however, was done with .308" bullets. It'd be useable for a starting point, but I'd suggest being cautious about working up to the maximum. COTW, 11th Edition also lists 3031 with the 150, with a maximum of 49.0 grains, but doesn't specify which bullet diameter was used for that data. Just watch your pressure signs and work in small increments. AAs 2520 should be about the right burning speed for this combo, but I don't have any data for this one.
