What would everybody (not that we'll neccessarily agree) consider the best .45 acp HP ammo? Especially non +P for better accuracy and quicker follow-up shots in a small, light weapon. Qualifications for best are 1>RELIABLE expansion in a short-barreled self defense weapon--3" barrel. 2>Velocity. On a side-note, I know some people prefer FMJ but gelatin-tests dont take into account that humans have bones that FMJ tends to bounce off of, whereas HP just slows down, flattens and would probably do more damage especially in a chest cavity. A head shot would be an exception because once youve made it through one side youre job is done, not always true with a "center-of-mass" shot.
