I see where you are coming from Old Grump. I take a slightly different but related approach. I didn't mention it in my earlier post, but I generally keep 4 to 8 hardcast semi-wadcutters or flat nose at the bottom of my magazines. I honestly expect most confrontations to be over before I get to those. However, I figure if I do get 4-9 rounds into my magazine and I still need to shoot that means either JHP was the wrong ammo to start with, or the assailant has had a chance to move behind cover that I need to shoot through if he is still a threat. So I go almost entirely the opposite way from JHP with something capable of excellent penetration and with as large a meplat as possible.
.45acp = Buffalo Bore 255gr Hardcast Flat Nose +P
10mm = Double Tap 230gr Wide Flat Nose Gas Check Hardcast
9mm = Double Tap 147gr FMJ Flat Point +P
.32acp = Buffalo Bore 75gr Flat Nose Hard Cast +P
As for my Revolvers, I don't really CCW them so the personal defense loads used above are more for home use. When I do carry one of them it is generally in the wilderness. Out there I carry:
.45colt = Buffalo Bore 255gr Keith Style SWC Soft Cast Gas Check
.44mag = Buffalo Bore 340gr Lead Flat Nose Gas Check +P+
Point being.... I like Semi-Wadcutter a/o Flat Nose an awful lot as well.... And I am even debating getting some of the BB anti-personnel Full Wadcutter to replace the JHP I currently keep in my revolvers.
