BS, Hornady has changed that powder. The new stuff is even better. Hodgdon makes it. Called Super performance, or SPF.

Hornady makes many cartridges with it. But, it appears they no longer offer it combined with Interbond bullets. You can get those nasty SST's in it. A bummer. I have X boxes of SPF/ interbond though in .270.....With X being a fairly large number. It wasn't ever made for the .257, so I just shoot accubond in it.

FYI
