1AK, I can tell you a big 220gr Speer will open on a white tail buck at 156 yards when started at 2175 fps from a Marlin 35 Remington, I center punched both shoulders as he lay beside a giant white oak waiting for the doe to get back up, I heard the bullet hit the tree behind him too, I need to go dig it out, he never got up, just raised his back legs and looked like a football player lineman for about 8 yards, then down again with another hit through both hams.
The bullet expanded, but didn't loose much meat either, I'd shoot a moose, elk or big bear with that thing, yours starting faster will only be better.
