Jeff, I dont have any first hand data but the effects of a tumbling bullet are heavily documented by the military. Mostly on the 62 grain fmj's shot from the 5.56 and the SMK (dont recall the weight) shot from the 308 winchester. I will do some searching and post some links to some of the data on tumbling bullets.

But because 308winlongrange found fragment in the yote that disproves my theory about the 215 grain hybrid not expanding and only tumbling. It could be possible that the fragment he found was from the tip of the bullet that blew off much like in Rich's (elkaholic) tests. I will do some searching and post some links to

Riley

Ok Thanks Riley. No need to post links for me. I have seen some of what you are referring to. Mostly about tumbling before entry.

As for the small pieces being from the tip like Rich's did. It is my opinion that was due to being pressurized and blown off from the water. But either way a 4" exit is a 4" exit and this was at a very low velocity. I just don't feel a non-expanding bullet, even if tumbling would make a 4" exit.

None the less I think we owe it to the OP to stop the hijack of his thread.

.308win, to take 2 yotes with a combined yardage of 2382 yards, 1.35 miles. Is something to be proud of. I took one at 1200 and another at 1156. I know what those little suckers look like in the scope at that distance and how the trigger needs to be broke to make a connection. Great shooting man.
