Looking for load advice for the 150 grain Hornady GMX in my 308. I got lots of Varget, RL15, IMR3031, and TAC. Anyone with any recommended loadings, please chime in. With my 150 grain SSTs, I use 3031, and get the best accuracy, but was reading the GMX bullets are longer, and 3031 might be too fast of a powder, which leaves me wondering, Please feel free to offer any other recommendations if the powders listed are bettered, as I'm not afraid to try something different, like 4895, or AR Comp. Thanks for the help! Steve
