Winchester AutoComp

Recommended Posts

Hey guys, I've been using Winchester AutoComp for a while now in a couple of .40 S&W pistols and the wifes been using it in her 9mm, I couldn't resist working up a load for my 10mm Auto STI 4.15 Tactical.

180gr plated FMJ's, 7.5gr Winchester AutoComp, chrono average 1210fps, no pressure signs.

I think I've found my new favorite 10mm powder :cool:
