I know, this isn't Caliber Corner, but I posted it here, because the question pertains ONLY to 1911 guns. I got an e-mail from Double Tap today about these loads. 160gr TAC-XP. The ballistics are truly amazing out of a 5" 1911 and I'm sure it would be a real doozy of a SD load out any length barrel to tell you truth. Just wondering how it feeds? I'm a big Gold Dot fan, and have enough of them, that I doubt I switch, but I certainly want to look into these. And if anyone else has tried them, let's hear what you think.
