VtBowhunter Posted August 27, 2005 Report Share Posted August 27, 2005 Take your bow to the local proshop and ask them to help you paper-tune it. You should be good to go after that. Quote Link to comment Share on other sites More sharing options...
dogdoc Posted August 27, 2005 Report Share Posted August 27, 2005 Re: sighting in broad heads dee--couple questions first: what is your draw weight? what is the length of your arrows? what vanes are you using and how are they fletched (straight, offset, or helical)? since you are not getting any consistent groups with your broadheads I have a feeling it may be more of an arrow problem rather than a bow tuning problem. Most of the times if your bow's center shot is off you will still get a fairly consistent group with your broadheads but they will be off from your field tips. Are you shooting a fixed broadhead? You could be underspined or you don't have an aggressive enough spin/twist from your fletching. todd Quote Link to comment Share on other sites More sharing options...
Tony Posted August 27, 2005 Report Share Posted August 27, 2005 Re: sighting in broad heads i cant also be that your arrows arent spin tuned to your broadheads.. when you put broadheads on you spin the arrows , if they wobble , then you can bet they will fly funny.. the reason this is mosty because of inserts not glued in properly... broadheads magnify the mis-alignment of the insert.. you cna tcorrect thios by putting a field tip in , then slightly heating just the tip of the field tip . enough to slightly turn the insert... then cool and put the broadhead on and spin it again.. if it spins with no wobble then your good to go.. if not continue heating and cooling until you find the right spot for your insert and broadhead.. i know its a pain in the rear , and i know it takes a while to do. but i can get my field tips and broadheads to fly exact by doing this.. now you also needc a bow thats properly tuned and arrows that are spined properly to get the best possible arrow flight you can..

dogdoc Posted August 27, 2005 Report Share Posted August 27, 2005 Re: sighting in broad heads [ QUOTE ] duravanes fletched straight [/ QUOTE ] that might be your problem right there! With a straight fletching you get no spin guidance from the fletching. Straight fletching is not recommended for fixed broadheads. Sounds like your broadheads are trying to guide your arrow--which=erratic arrow flight. There might be more to it and your bow may be out of tune but that is where I'd start. Do you know the weight of your arrows? todd Quote Link to comment Share on other sites More sharing options...
Guest shtr Posted August 27, 2005 Report Share Posted August 27, 2005 Re: sighting in broad heads Sounds like a small tuning prob. that can be worked out simply by finding out what the broadheads do diffrent than the field points. Start at 10 yards and see where they impact with the broadheads. If they are low move the nock down and if high then move the nock up . Do this till the hieghts are the same. Now is the arrow hitting to the left or right?. if right , move the rest to the left and visa/versa. Once you are on move back to 20 yrds and repeat untill you are to 40yrds. This is termed flight tuning and if your form is good there is no better way to tune a bow. In fact,I dont know of any top shooter who tunes any other way but they will reccomend paper tuning simply because it is easier to see what is happening regardless of form. Good Luck!!

Guest shtr Posted August 27, 2005 Report Share Posted August 27, 2005 Re: sighting in broad heads Thats a new one on me !? Not saying your wrong ultra but I have never seen it and I do perhaps a few hundred dozen a year. I could see it if you were useing heavy adhesives and not flushing the insert to the cut though. Interesting comment all the same. Quote Link to comment Share on other sites More sharing options...

I know someone will disagree since they may have had a set up that did shoot them well but it still is not the best combo. IF you have any tuning issues then they will be extremely noticable with fixed blade heads. Paper tune a Bare shaft tune it (if possible for you) then try a good offset or even helical fletching. Or go to mechanical heads which fly exactly like your field tips... Either way you should put some new vanes on with offset or helical if your going to shoot any type of broadhead. Good Luck!
