I have a XP100 in 350 mag. You really known when you touch one off. Extremely accurate. I load it down to 35 remington levels and can handle a box or two in one sitting if I had to. With full bore 350mag loads I gave up trying to shot for groups larger than two shots. I know the the third is going hurt so darn bad. I know that two shots will be touching exactly where I want them at a 100 yards plenty good enough for deer.
