Re: SUPERFORMANCE POWDER is SUPER in 260 REM.
Thanks for posting your experience. I have personally had mixed experience with this powder:
I originally bought it for my 22-250. Shot terrible. Worst powder for accuracy in that rifle I have ever found. It was rotten.
I was pretty convinced I got sold a load on some "rocket sience" marketing drivel. In looking at the container, they listed 300WSM data, so . . .
I loaded up a box with 168 gr ttsx as the pill. Best powder I've ever shot for accuracy in that rifle.
So - the old adage holds - don't knock it til you try it!
Good shooting, Happy Easter!
