Dox,
I used arrows with a total wieght of 445 grains. My bow is set on 58 pounds. I blew through warthog and impala like butter. Drove the arrow into the oppsite shoulder bone on my kudu so deep the skinner said he couldnt get it out without pliers. Shot me zebra quartering away hard. Went through last rib, stomach, chest cavity with the point barley breaking the skin in front of far side shoulder.
