A little bit off topic as I have not used the smaller caliber hydro's. But what I do know is that if you push the big Woodleigh Hydro's hard they can travel a long way through an animal.
Below is a young Buff I shot for meat with a 400gr Hydo bullet from a .416 Weatherby mag at 2730fps.
This was the second shot as the bull turned to run after my first soft point bullet hit him on the opposite shoulder. I had some Hydo's in the magazine ready for the second and third shot if needed.
He dropped on the spot as the second shot, a 400gr Hydro raced through his body.
It completely penetrated the entire length of the buff's body, exited through his neck and then ironically went through his ear and kept going off into the scrub.
I would not have believed it if I had not seen it for myself. This is the only one I ever shot from the south end of a north bound buffalo with a Hydro. I never recoverd any other Hydro's as they all passed through on side on and angling shots as well.
