In my experiemce, I shot it into the offside hide thru my cape buffalo shoulder. Full penetration on many many oryx. My cousin used it on his lionness over 400lbs. I?ve also used it on mamy elk as well. Does more damage than any other bullet ive used. I will comment that u gotta run em hard and they will work. I run mine over 1750 at a minumum. 1850 to 1900 preferred. Run em slow and they will perform as described above.
