[QUOTE="Reloader, post: 83398, member: 2555"] H4831 has been my best and most consistent powder choice in my 300 WM w/ 180 HDY HPBTs, 180, 190, & 200 MKs. I like 73 grns under the 190s and 73.5-74 w/ the 180s. Velocity w/ the 190s and 180s is around 2900 @ 12' from a 26" tube. IMR 7828 has been my second best powder in that round w/ IMR 4350 nipping close behind. The 4350 seemed to provide low SD in velocity but groups were erratic. Good Luck! Reloader [/QUOTE]
