300wsm 180 gr TSX
I will take pics of the one Barnes I recovered after going through over 2 feet of a 500 pound black bear, thru one shoulder, all the goodies through the far shoulder and perfect mushroom under the far hide.
Didnt recover the one I shot my 6 X 6 elk with that day, straight thru the shoulders, DRT
A month later I shot my biggest KY whitetail to date, 11 point shot texas style, traversed the entire deer and found after 4 feet of penetration perfectly mushroomed.
257 Weatherby 80grain TTSX
Shot my B & C antelope, 284 yards, DRT, thru both shoulders, hit the far shoulder, exited to God knows where.
When I read about a guy using a 7mm magnum and 150 grain TSX and it didnt expand I can only say, duh!
Caliber for the animal your shooting and the right bullet. No a Barnes X wont open much side to side on most deer, but get a raking or full length body shot and they will, on deer broadside deer I shoot thru the shoulder or high shoulder, the bullet doesnt "blow" up and punches nice little hole thru deer.
You cant use a cannon on a mouse and expect it to expand
