I have killed deer with the Tigersharks, and landsharks with a 43lb @ 28" Hummingbird longbow, I pulled it about 29 1/4. They were 100lb does, I have killed several 170lb plus bucks with them and a 51lb @ 28" Hummingbird longbow same arrows as on the 43lb. I have killed 3 does with Treesharks w/ 56lb @ 28" Hummingbird longbow. I shot a 165-175lb buck Friday with a Tigershark, he was quartering away steep and put about a 6 inch hole in him it lodged in the off shoulder, 23" of penetration. Just get them sharp.LCH
