I guess this is as bad as I`ve experienced with "bullet failure"..

This was a 180gr XTP fired at 1700+ fps MV and hitting a four horn at 40 yards so you can get an idea of impact velocity... He was an extreme quarter toward and at the shot he was lifted up on hind legs and over on his back....The front leg/shoulder bone took the entire impact and what you see is what I found. Shot him through the ribs to finish... Talked with Bob Baker at the YO that year and he said "its a rare shot when an XTP did not penetrate a shoulder bone"... Anyway ...that`s my failure story... You bullet test guys are doing a service for handgunners....
