I am going to be reloading some 168gr Bergers for my 7mm RM soon. I have been reading about different types of powders and the results people have been having with them. It seems like the most common findings are: 4350 or similar for light to med wt bullets 4831 or similar for med to heavy wt bullets H1000/Retumbo for heavy wt bullets I am looking for a powder that is extremely temp stable and has lowest ES. Just want it to be flat out consistent. I am not as worried about the absolute hottest velocities. I would much rather take shot to shot variance out of the picture. As you can tell from all my research and quite vague summary of findings, I'm a total noob. Thanks for any feedback. BTW, will I see much difference between H4831 and H4831-SC? If so what are pros and cons.
