    Have seen a reference to this powder. Can't find any info. Has anybody heard of it and if so what is the proper application? Rifle? Pistol? Shotshell? TIA

    It's been discontinued. It was offered up until a year or so ago. It is a useful powder in some magnums and similar cartridges. I have loaded it in 7MM Mag and .270. There may still be some available out there, since it was pretty popular with some reloaders. It is a very slow powder, compared to most others. It probably was slower than H450, H4831, and Winchester 785 if you can believe some of the powder burn rate comparisons. I believe it was extruded, rather than the usual ball powder that Winchester offered. You might take a look at www.wwpowder.com and see if there is some data still offered. I believe the new Supreme 780 has replaced it.
