I just returned home after a successful morning hunt here in Southern Michigan. The Bucks have been chasing Does up here for a week now and the hunting has been hot. Halloween morning I killed a nice 6 point Buck with a huge body and decent rack he was the 8th Buck that I had seen that morning and the 2nd Buck that I shot at. Unfortunately I missed his older brother a nice 8 point 2 hours before the 6 came in. I tried to shoot through a window in the brush and concentrated a little too hard on the one pencil sized limb that I did not want to hit, well I of course shot right into it and it deflected my arrow into a 4" diameter tree. The arrow stuck in the tree 6 feet off the ground and I had to break my spruce wood shaft off as I could not free the Zwickee. Anyway, I shot a nice Doe this morning and to my surprise, she was coming into heat. If I would have noticed that I would have let her walk. I shot her at 17 or so yards and blew completely through her shooting my 51# limbs on my Schafer Silvertip. That is the lightest weight bow that I have killed a deer with and am very impressed with the results. I shoot spruce wood arrows of my own build and they only weigh 512 grains with broadheads. The heads that I use are the big Zwickee Deltas that weigh 135 grains. I have a set of 60# limbs for my Tip and those were the ones that I used on the 6 point but I really like shooting the lighter weight 51s and if I can get this kind of performance out of them, I will continue to use them. I actually got better penetration on the Doe than I did on the Buck even though I was using the lighter weight limbs. I did notice on the Buck that I went through ribs on both sides and did get a broadhead pass through which is all that really matters, but if I can get complete pass throughs with the lighter limbs, why not? They are a joy to shoot. I won't let anyone tell me that you nedd heavy bows to pass through deer anymore.
