The H&K USP-45 is often described as a tank of a gun. I wonder if it could hold up to .45 Super?
I believe so though I cannot, at this moment, recall where I read it. The fullsize Springfield XD will handle it, the Glock 21 and select 1911s. As with many things, it depends on who you ask.
I've got a HS6 load for the PPQ 45 that scoots the Lee 452-255-RF to 853 fps from a 4 1/4" Walther PPQ45. There's a little throttle left on that one, but I am familiar with those ballistics and satisfied with them.
