Shortly after the introduction of the .357 Max, Remington introduced a 158 gr. HP designed specifically for that cartridge. The profile was slightly different than R-P's then existing 158 gr. bullet intended for the .357 Magnum, but it was with a much tougher jacket. It was a colossal failure market wise. Many years ago, I picked up some from Midway's closeout bin. It was a great bullet for the Max, .35 Remington, and pigs in the .357 Magnum. No clue as to why it failed.
