Hi
I shot one impala in 2006 with a Game King, fully broadside shot just behind the left shoulder in and behind the right shoulder out, left a nice blood trail for the full 40 meters he ran. (140gr @ 2550 fps) Little bit of blood shot meat.
2007 I used 140gr Hot-cor's also @ 2550fps to shoot 2 more impalas and another one, 2 weeks ago.
The Sierra didn't do anything wrong, but I just liked the Hot-cor more, I will keep on using the Speers now.
Sweet
