For what it's worth, I finished off a big old cow elk who decided not to stay down when we approached her. It was an intinctive thing and I got her in the back of the head from 30-35ft with a 40 and 180gr XTP. It hit her about 4" behind the skull and shut her off like a switch.

I've tested 310's at 1200 and 1400 in milk jugs. You'll need at least 12. I only had 10, then 11.

I belong on eroding granite, among the pines.
