I've heard that too, but aint personally seen it. I've shot them in as close as 20yrds, but that one was a neck shot. The couple deer with chest shots at about 60-70yds worked fine too.
Not that it cant happen with proper shot placement, thats just my experience. I would agree that its probly the speed.
On a side note, I helped my uncle cut up his elk today that he shot with a Barnes Triple Shock I think he said. With his 270 WSM and that thing is pure junk as far as I'm concerned. It didnt even expand to full caliber diameter. It had lots of penetration. Quartering away and the bullet went thru the gut, thru the vitals and imbedded in the base of the neck by the shoulder. He did get the elk however.
