I'm thinking it may be an excellent choice in my 6.5x284 when I get it. The rifle is to be completed sometime around the end of August. It is purported to be in the IMR4350 burn rate range but with higher, sometimes MUCH higher velocity, and of course, better accuracy.
Apparently, Alliant had the short magnums in mind when developing this powder. I plan to have Kirby build me a 270 WSM in the near future and would also like to try it with this cal also.
For unknown reasons to me, Alliant is having this powder produced in Switzerland, so availability may continue to be postponed. As I know it, this powder was to be available by March of this year, then pushed back to the end of June.
I have not seen any yet and have my requests out to 3 stores. I'm guessing that a reasonable eta will be later this year, much later.
