[QUOTE="MagnumManiac, post: 2258156, member: 10755"] Two pieces of evidence stand out, the bullets were either oriented backwards or sideways, showed evidence of expansion on one side more so than the other and a wound channel that had a secondary expansion after a large bone was hit. This is evidence of a bullet tumbling. It only happens once the bullet has slowed considerably in my experience culling large critters like water buffalo. In gel tests, every single FMJ with a boat tail tumbles just after entering the gel and exits backwards. On the high speed, the moment the bullet tumbles, the expansion in the gel is 3 times larger than normal, a conventional bullets expansion as it tumbles is generally double normal expansion. FMJ hunting bullets with wide meplats, like those made by Woodleigh, do not tumble and are pretty good at staying straight, but we have seen those deviate at ridiculous angles too, the worst culprits in that aspect are RN FMJ’s. I wouldn’t expect for you to see many Ballistic Tips tumble, unless a large bone is hit at 3/4 of it’s penetration, although this doesn’t guarantee such an occurrence. Cheers. [/QUOTE]
