I am not sure that this phenom exists consistently enough to count on. Of the deer I have personally killed only three would be descrribed as Bang Flop and one nicked the spine. The other two were lung hits and it looked like thor smacked them down, one didn't even twitch, both were under 100 yards with 165 gr bullets from a 30-06(corelokt and spper hot cor). All the others did the less than 100 yard dash before skidding to a halt. The other side of the coin on this is a doe my son shot last year at about 150 yards with a 270 with sierra prohunter 130. A solid lung hit, above the heart, clear through both lungs, no bone she went about 400 yeards through the bush before tipping. I am amzed when the Bang Flop thing happens, but I was shocked when we had to go so far for that doe.
