Haven't worked too much with the 165's in the 300WSM, other than for my buddies M70 EW 300WSM. I used H100V and tried IMR4350 as well. H100V shot about the best at 3130 or so. I run alot of RL19 for the 180 AB's though, it is really accurate in my rifle and runs right at 3030 in my rifle. When I visited the Nosler factory, their head ballistician saif RL19 was THE powder for the 300WSM.
Nosler has not tried RL 17 yet, when they do they will see that RL 17 is the powder for the 300 wsm.
