Speer 44 mag 270 gr Deep Curl Performance on Game?

[black mamba]

I have been getting some wonderful velocities and accuracy with the .429" Speer 270 Deep Curl JSP in several different 44 mags.

I'm wondering if anyone has used this bullet on game. I would like to know:
* on what animals?
* at what velocity and distance hit?
* bullet expansion and penetration (or lack thereof)?
* and general effectiveness?

This bullet seems to be a perfect balance between weight and velocity with controllable recoil. Thanks for the replies.

I've been doing tests of factory loaded 44 mag premium bullets on red deer , 250 lbs .The Federal Swift A-frame and Corbon DPX [all copper barnes] were excellent penetration and expansion. One shot kills at 50 yds !
The Deep Curl was hotter than both of those so I chose not to use it in my old S&W M29.I have no doubt it would perform at least as well as the other two. All comments I've heard are that the bullet is both accurate and performs very well and thus the dealer says it's very popular ,more so than anything else.
Practice ,practice and get your deer !
