I shoot the 311284 in several 30-06 rifles with good results. I water drop the bullets cast of WW, Size them to .312, with Hornady GC. I Lube them with 50/50 Alox/Beeswax, and Lee Liquid Alox. I find the best accuracy for my combination to be 1800 to 1850fps. I like Alliant RE-7, IMR 4895, 4759, And Hodg BLC-2 as propellants. 311284 may be a bit long for a .308 case, I'd Like to know how they shoot for you.
