I try to shoot, and test different rounds before I use them for CCW. I look for accuracy, reliablilty, and performance in various tests I use.
for my .45ACP guns, I like Fed 230 grain HydroShock
for the .45 Colt revolvers, I like the CorBon 200 grain JHP
in .44 Mag, for CCW, I go with CoreBon 165gr JHP
in .357, I prefer my hand loads, Speer 146 grain JHP over Unique Powder
in .38 Special, I am partial to the 125 grain NyClad
in 9mm Lugar, the 124 grain HydroShock, and in .40S&W, the 180 grain HydroShock.
