Most accurate only means most accurate in their test gun I take their accuracy recommendations with a grain of salt. If imr 4831 is all you have then that's what I'd use it's a very good powder as long as it's decently accurate in your rifle. The following powders will work imr & h 4895's, RL17,19 &22, imr & h 4350, win 760 & h-414 the same powder different label, imr 4064, imr 3031. If your rifle shoots well with imr 4831 that's all that really counts if not I'd look at h or imr 4895, possibly RL 17 or 22, imr 4064 and the 4895's have given me decent accuracy in 06's, actually h-4831 has given me very good accuracy at the expense of a little less velocity in the lighter bullet weights. I don't think you are going to have a problem finding at least one or more suitable powders.
