Only tried this is several 45 ACPs. It shot well and functioned in all but a Kahr CW45.

AFAIK, beartooth bullets is defunct. I've subsituted, the RCBS 270gr SAA sized to .451 and seated to plunk (OAL 1.200 +- for both in my guns) and function thru your magazine for almost identical results.

Have worked with 45 Super in HK USP for a bit more velocity and 460 Rowland (in both 1911, and HKUSP) for more velocity yet. The load pictured above functioned with no gun mods - if intended to shoot a lot, would go with heavier recoil springs and flat bottomed firing pin stop in 1911s.


FWIW,
