[QUOTE="hypersonic, post: 975300, member: 5217"] IMR-7828 you should top out at about 77-79 grains perhaps a grain more or a grain less depending on your rifle and the capacity of your brass as always work up from below looking for pressure find your rifle's safe max and work from there on seating depth. I have a load with the 185 Berger in my 300 Win it is 77 grains of 7828 in partial resized brass. I went up to 80 grains fair bit of compression in the case and a little bit of primer flattening but nothing scary. 77 proved to be the most accurate and I will take small groups with a little less speed any day. If I need more than what this load will do I'll haul out the 338 RUM. You should be able to find a load pretty quick in the 300 with a quality rifle the Win is a pretty well behaved cartridge that does well with a lot of bullets weights and powders. [/QUOTE]
