Best Powder for 300WM 200 gr Accubond?
I'm going to work up a load for my buddy's 300WM for our elk hunt in October. What powder would be the best burning rate and stability for this round with the 200 gr Nosler AB? I have IMR 4350, 4831, 7828, RL22, H1000 and Retumbo on hand. I have seen similar top velocities listed in various manuals--2950 to 2975 fps-- with powder ranging from IMR 4350 to H1000. Case capacity is a consideration since this is a factory gun and the rounds have to be seated for the magazine. The loads of 4350 were 8 or more grains less than the H1000, I don't remember exactly. 4350 seems fast for a 200 gr bullet and H1000 seems slow.
I have had great luck with IMR 7828 in my 7STW, 7RUM and 338RUM. Anybody tried this powder for 300WM 200 gr AB?
Thanks in advance for your input.
