I have had four out of six Ballistic Tips "stay" in the moose I've shot with them. The two which exited were early version 180s in the '06. (The others were 200s out of the 340.)

I can recall shooting seven X type bullets into moose. Only the 140 out of a 7mm-08 left the scene. The rest were 225s in the 33 and 35 calibers.

I have a 150 Partition which was stopped by a whitetail on a broadside/angle shot from a 308. That bullet is far too stubby to make a decent moose hunting bullet out of any 30 caliber IMV.

You won't go wrong using heavier bullets on moose. And over penetration is not a concern with moose as much as it is with many other animals.

Sometimes, the air you 'let in'matters less than the air you 'let out'.
