[QUOTE="SSG Graybush, post: 2859003, member: 115190"] 180s, I'd use H4831sc or H1000. I'd start with H4831sc. I've found for 150's, RL16. 165-180, H4831sc. 200-208's H1000. RL16, Hodgdon "H" powders and Varget are pretty temp stable. You can find charts for fps variances per degree of temp on line. You need this info for your ballistic app to adjust correctly. And always remember, if you develop a load in the winter it could be over pressure in the heat of summer. I wouldn't get hung up on trying to match that speed, a dial is cheaper then components. You should chase constancy, sub .5 moa and a ES <15 fps. [/QUOTE]
