This bullet was recovered from the hard barrier hard wood plyboard test and was recovered from the first board. The 125 +P JHP from REM. went through 2 boards as did the Corbon DPX 110 Grain, both of these bullets chrono'ed 810 FPS. The Lead bullet is very soft lead.

That would be the snubby barrel?

Yes it is.

A bit confused here -- those are 2 different bullets,right? Which is which? From your comments it looks like you're saying the top is the 158, the bottom the 125. The tests I have made in wet-paper medium demonstrate the same sort of results, except the 158 looked like the bottom photo and the 125 like the top, with the 158 penetrating almost twice as far as the 125.

There is 2 pictures of the same bullet from different angles.
