I took a deer last fall with a 357 rifle , shot it in the neck broke the spine and dropped right there, but the bullet only went a couple inches past the spine , this was a 200 lbs buck , did the 357 work yes , will I do it again with that load NO . A pistol 158 grain JSP is probably designed to expand at velocities as low 1000fps . At a chronograhed velocity of 1825 fps 15 feet from the muzzle , this bullet was probably going 1700 fps at the 22 yards I shot the deer at , too much for a plain JSP , a 95 grain lead pancake is all I found of the bullet , jacket was never found , taking a deer with a 9mm rifle is doable but the hunter has to be a diciplined person that will pass up all but the best shot, If taking a deer with a 9 mm is your goal go for it , if deer hunting is your goal get a more than capable rifle because things can get weird when deer hunting . Taking a deer with my little Rossi 357 was a goal for me , and it took 3 seasons to accomplish it
