[QUOTE="el matador, post: 1106319, member: 12193"] I agree with earlier posts about consistency, especially weight sorting brass. You can do a lot to lower your ES, but the fact remains that some loads just have a higher ES than others. I load for 3 different 300 WMs, all shooting the 208 Amax with H1000. One likes 76.0 grains, another 76.8, and the third prefers 78.0. The 3 rifles shoot 3/8, 5/8, and 1/2 MOA respectively. The loading data gives a max charge of 78.0 grains with a seating depth around 3.4" if I recall. You are seating your bullet quite a bit further out than the loading data indicates. That creates more room in your case so you can use more powder before reaching max pressure. Nothing wrong with using less powder if that load works for you, but you do have the option of finding another accuracy node in the 76-78 grain ballpark. That load may or may not have more consistent velocity. [/QUOTE]
