Over the past few years, I have received a ton of emails and PM's from folks wanting to know if they had enough horsepower to shoot Treesharks out of their 45 pound bow. Having never killed a deer with a bow less than 60 pounds, I never could give them an honest answer. I knew Mr. James Wrenn always said he didn't have any problems shooting through deer with Treesharks out of light bows, but I'm not one to give advice if I don't have personal experience to back it up. This year I decided to do all of my hunting with a 45 pound bow, just so I could personally shed some light on the subject.
With my Centaur being my lightest bow at 63#, I had to borrow. A friend of mine had a Bear takedown that is exactly 45# @28". He said I was welcome to use it, so I got it tuned up and ready to go. I didn't do anything fancy with my arrows. I ended up with Gold Tip Trad 1535's cut to 29.25", with 190 gr. screw in Treesharks up front. I haven't weighed them, but from my figuring, they should be almost dead on 450 grains.
I've had several close calls over the past week, but it finally all came together yesterday afternoon. I got a 7 yard shot on a 6 point at Horse Creek, and it did the job. The arrow disappeared into the deer and, judging from the dirt caked on the head, stuck in the dirt. With the low hit at close range, the rear half of the arrow was still in the buck as he started to run. He drug it with him about 20 yards down the trail.
The experiment will continue for the rest of the season, but it's looking like 45# IS enough!
