from a quick glance at Alliants website I need to try this stuff in the 308,6mm,and the 270 WSM,,anybody gave it a whirl yet???
 
It's my favorite powder. I get near WSM performance out of my 270 Win. I haven't loaded for my -06 yet. In the 300 WSM I'm getting 150 fps faster with no pressure signs. It is VERY finicky in my 270 Win. .1 of a grain off and your loads can differ significantly especially when near max loads. Not so finicky with the WSM.

I may try it in my 264 Win Mag.
 
I have shot almost 2 pounds of it.

It's pretty accurate in my muzzleloader.

It seems to be a hair slower burning than H4350 (also very accurate in my muzzleloader).

Have not tested it in anything else yet.

Im going to work up a load with a 168 gr Barnes TTSX for my 30-06 with it very soon.

I've got some 150 tsx loaded up with it for testing in my 300wsm. Other responsibilities have prevented my range time lately.
 
In my winchestor model 70 in 300wsm the average velocity for a 150 grain sst is 3340 fps. this is through the chrono and the groups are hovering around 1/2 to 3/4 inch. i am very happy with this powder.

I am loaded up to 70gr max with the 150 tsx in .3 gr increments (from 66, I think).

Thanks-
