I used it in my .308 win and it did not do well. Used in a dpms lr 308B and a custom rem 700 308. accuracy was ok..... could not get velocity out of it with 155 gr. SPMK or 168 gr. SMK signs of high pressure before i could match any of these powders. IMR-4064 out ran it, Varget out ran it, and CFE-223 out ran it. also meters poorly as it is a stick powder. meters like IMR-4064. might be better with a different weight bullet. i made some hunting rounds with the rest of it and will not buy it again, it is expensive and i can find way more suitable powders for the .308 win.
