.45 ACP:185gr Remington Golder Saber +P They seemed to have the best expansion, velocity, and mass retention of all the tests I read. They shoot great and feed great.
was playing with a ft lbs. calullater today and a 45 185gr at1000fps is only 411ft lbs
Why bother? Because you can get better combination of energy and expansion from a 185gr .45 ACP +P defensive round than you can in:9mm.357 Sig.357 Mag10mm.40 S&WShow me a round that has better numbers than this:500 ft-lb of energy.75" diameter after expansion100% weight retention (in a published test)... that I can shoot in a compact auto. And I'll be heading to the store to get it....The only reason I would choose something over the .45 ACP +P for a manstopper would be if you need to shoot through heavy clothing, windshields, light cover, etc. In that case I would choose the 10mm.
357 SIG 125 gr. Ranger 500ft lbs .75 expansion havent found a published weight retion yet but ill keep looking
