I am pretty new to archery and am going to try turkey hunting this year with my bow, to get my first bow kill . Anyway, I was wondering the different methods you guys use to tune your bow to get it in top form for deer and turkey hunting. I was told that I could be shooting good groups but if my bow isnt properly tuned, I could loose a lot of energy and penetration and possibly wound my target. Any methods and instructions how to do so would be great. If theres a website or something that shows all of this that would be great. Thanks for the help. I have a compound, 56# draw, pretty standard beginner setup.

I just posted on this subject.

The only thing I'll add is that tuning for broadhead flight is more critical than tuning for field tips. It is very important to design and fine tune your arrow for the correct spine. You also want to make sure you have enough weight up front. Light weight broadheads on improperly spined arrows are the biggest reason penetration can be poor on high draw weight bows.

Loading weight on the front end and creating high drag on the rear of a properly spined arrow will give you a great shooting, high penetrating broadhead tipped arrow.

Download eastons tuneing guide , go straight to broadhead tuneing , there are other methods of tuneing listed , some are for traditional archers ,others are for compound archers useing a release , dont get confused useing a method that was not intended for the gear you are useing , for example "bare shaft tuneing " , which is intended for traditional archers to fine tune thier arrow spine .

Thanks... the Easton link is awesome and very helpful.

This is one of the most accurate statements I have ever read on this or any other forum.


You must have alot of drag to get heavier arrows to fly well,traditional shooters understand this.Along with the heavy points.

Light and fastarrows need low drag and moderate point weight.


You can play the other end of the spectrum with great success also but when you start trying to combine the 2,that is where problems will arise.

300 grain carbons with 5" shield cuts with 9% foc will do horrible with penetration out of most setups.


I also agree that if a fixed blade head is to be used,you need to tune to them.I mentioned that BRIEFLY in my post.

I'd be willing to bet that 300 gr carbons with a 9% FOC would have terrible penetration out of any setup - nevermind the fletching.

I actually had a 320 gr arrow shooting 1 1/2 Rockets with low profile vanes that was shot out of a speed bow that did amazingly well at relatively low poundage.I did have foc around 11%.



If the ke was REAL high on the light arrows ,they would get passthroughs on good hits but bad hits wouldn't fare so well.


The problem with the feathers would be that the arrow would be unstable at high speeds with that much drag,that was my main point.

What is FOC?

Thanks

Front of center,the amount of weight that is infront of thecenter point of the arrow.The balance point.
