EVERYONE ???? I AM NOT !!!
The 158gr JHP/JSP/SWC bullets are the standard original bullet weight in the original 357MAG cartridge. Therefore it is that by which all others are judged. The 158gr SWC bullet was designed as an all purpose bullet buy KEITH/SHARPE ETAL to be used to shoot anything in dired need of a thirty-five caliber bullet hole. It worked pretty darned fine too until the ammunition companies started to attenuate the velocities of the load due to pressure problems in SOME guns.
The 357MAG cartridge with 125GR JHP bullets [ usually ] was designed to whack 2-legged varmints with a much higher velocity bullet that expanded violently dumping energy into the two-ledded varmint much more quickly. THIS IS DID WITH ALACRITY !!!
