I have used various Barnes X bullets since 1999. Last critter I shot was a decent sized boar black bear with my 300 Win Mag and the 200 LRX. Range was about 50 yards. Bear was mostly facing me (I called it in). The bullet entered where the neck joins the body but on the side then penetrated through the chest, broke the offside front leg bone, exited and then entered the rear leg. I dug it out and cleaned off the perfectly mushroomed 199 grain bullet. I am a big fan.
