Hornady Superperformance powders

[RemBRshooter]

Has anyone tried this powder in a standard 6br with 70 to 90 grain bullets ?

There's probably a lot of guys more qualified than me to answer your question. But I think it will be on the slow side, where you wont get any velocity from it.

Superformance has a similar burn rate to that of H-4831,R-19,N-160,etc.... I have not personally tried it in a 6br,but I have to assume that it would be a good bit too slow burning to be effective.
