I've only recovered threebullets, all from game shot with them. One was from a black bear, and two were from large mule deers. All were Nosler partiton bullets, and all had gone almost completely through the animal on quartering shots, and all were found stopped by massive joints, like the big bones of a hip joint. All were perfectly exopanded, and all were missing the FRONT CORE, having performed as designed.

I do not consider penetration of a mere 4" of wood with the loss of the entire core to be satisfactory performance, but the Corelokt bullet does much better when it hits flesh rather than wood!
