My bow that I used on my trip I just returned from was 64# @ 29". It shoots a 720 grain arrow 186 fps. The arrows I used while there were 671 to 800 grains. I shot a Zebra, Kudu, Nyala, Eland, Red Hartebeest, and Impala. On the Nyala, Kudu, and Impala the arrows blew through the animals and kept right on Going. On the Kudu and Zebra the arrows were hanging out of the off side by the feathers. The Eland was the only animal that the arrow didn't at least come out of the oppisite side. The arrow did go through the meaty part of the shoulder in front of the crease, through the chest cavity and heart, out the chest cavity on the oppisite side and into the off side shoulder. Thats good enough for me. All but the Eland where shot with a Zephyr Sausquatch that is 1 9/16th inches wide. The broadhead I shot the Eland with was a hand forged Damascus steel trade point that is shaped like a Journeyman and 1 1/8th inches wide.
