I did a 8' brown bear with a 375 gr. X in a Taurus Raging Bull .500 S&W at 129 yds.-1 shot and a lioness with a 275 gr. X in a .475 gr. FA Linebaugh at 22 yds (2 shots in shoulder). All bullets were in offside shoulders expanded perfectly. (I couldn't get any of the photos to post!). I like handgun Xs for big, dangerous game.
Also did a 12' croc with a 185 gr. TSX in a .325 WSM XP. Like I said, Xs and dangerous game go together and they work perfectly well on non dangerous game. Done a bunch of groundhogs and deer with different calibers.
