That looks like a big, mature cow.
I slayed a 6x6 bull last Friday with a dreaded [gasp] AMAX out of my 6.5x284. DESTROYED the heart.
Damn target bullets.
I've got some 105's waiting to be loaded for my .243 RAR Predator w/ 12x Super Chicken.
Not sure I'll launch one at an elk, but deer and antelope are going to be in trouble next fall!
