Default Cannot get BHs & FPs to hit the same

Been through the Easton tuning guide several times over, had new string put on, moved nock pnt. every wich way. They just will not cooperate.[&o]
I'm getting very tight groupswith bothbut the Bhs are 4" high.
I'm giving up.[>:]I guess I will just have to move the sight upbefore hunting.
Anyone else have the same problem ? ,Or any advice.

Where in NY do you live? If your close to me I bet I can help you get this done. I know a lot of people have different opinions on broadhead flight on this site....I personally tune my bow so they hit together though.

What is the spine rating on the shafts your using, is your setup exactly as described in your signature? Assuming everything is spined correctly, and centershot is true....moving your nocking pointup 1/16" at a time should slowly bring that group together.

I have different feelings about this. If your arrows are flying right and you have no other problems why not just move the pins when hunting season comes. You keep messing with your stuff and you may find you have more problems to deal with. I say if it ain't broke don't fix it. Thats just my 2 cents. but I.m just an oold deer hunter what do I know?

Where is it written thatall broadheadsshould group exactly with field points? This doesn't make sense to me. You are totally changing the aerodynamic characteristics of your arrow. Of course they are going to be a little different. I've seen testing where a perfectly tuned bow shot out of a machinecan put one broadhead into the field tip hole. Switch broadheads on the same bow / same arrow and you miss by 5 inches. Does this mean the bow is out of tune? No. It just means that broadheadsfly different! Different from each other and different fromfield points. As long as your broadheads shoot tight groups I'd be happy

I agree with you qzq38b,

IMOit's better to tune using the bow and arrow combofor what the bow is intended to be used for. If it's hunting, tune with broadheads. Don't worry about the POI of a different arrow/point combination.

I've gone to the extreme of having two seperate sights. I tune and sight in for broadheads with one and then change sights when I want to practice with field points.

Myself, I have have seen the opposite as alot on here. I have bareshaft, paper, and fine tuned bows, and found the broadhead tuning is the best for both tight groups and actually in tune. Thats if you stick to good simple broadheads like muzzy 100 and thrunderhead 100's. You start getting fancy, things change.

My last bow I got, the dealer said it was tuned up, and I shot it thru paper and it was bascially bullet holes, bareshafted and they hit pretty well same place. But didn't group well at all for what I am used too. As soon as I put my BH's on, picked out the straightest arrows, and matched the broadheads and arrows for simular spine and spin test, I gotgroups 4" low. As soon as I raised that knock up, my groups got smaller instantly with both tips and BH's.

I have seen it so many times where pro shops swear the paper and bareshaft is the only way to go. But I prove wrong. I have a feeling I know why, its easy for them to do and they don't have to have alot of space for it and not near as time consuming as BH tuning, dont' tear up targets near as much.

Sure different broadhead might hit differently, but I bet 90% of the time its cause some plane more than others or have more bearing surface to plane and this shows form problems, if the BH are straight and the blades are, best bet is BH tuning.

I used to feel the same because I thought that unless they did there was something wrong even though the 2 arrows were there staring me right in the face. They are not the same so I don't make them be the same. To do so is IMO a comprimise. As long as they hang out, BH's with BH"s and FP"s with FP"s I have no problems. I'm with the others on this.

There is a guy right in your area that would jump at the chance to help out, (he does like them to be together) goes by the name of Bowtec and can be found here. He thrives on helping out.
