[QUOTE="geocodyrgia, post: 2063419, member: 98212"] I use 7828 in my 6mm Creedmoor and have found 8t to produce best accuracy for me at the 400 yd line over: RL22, RL19, H4831 and IMR4451 with the 108 ELDMs I use. At 100 H4831 did better by a bit and I expected that to translate to better groups at 400 but that was definitely disproved. I will say that 40* colder Temps and a fresh can of powder (same lot) changed group size more than a little. I was testing for seating depth and the deeper seated rounds shrank groups a bit so wondering if that says anything about what this powder likes in my large rifle primed cases. To figure out my starting load I looked a a couple books and then tested 3 cases filled to the bottom of the neck, averaged those for my max load and worked up to that with great success.
