Over the years I have rarely had my broadheads impact with my field points, but always within 2 to 3 inches requiring just a small sight adjustment.
However this year I am realy confused because the broadheads impact 4 inches left and 7 inches low @ 40 yards from the impact point of my field points. The broadheads do group good (4 inch group @ 40}.My bow is shooting a bullet hole in paper at both 6ft & 10 yards and a bare shaft hits within 1 inch of a fletched arrow at 15 yards with this set-up.
I next adjusted the broadheads to impact with the field points (per the Easton Guide) by moving the rest up and to the right until they are hitting the same point at 40 yards, "BUT" now I have a 2&1/2 inch right tear in paper and my groups opened up some at 40.
??? Do I put the set-up back where I started or go with the Easton Guide set-up which is supposed to be the way to set up broadheads.

Sorry to be so long or my first post but I realy value the knowledge on this board and the experience you have had with broadheads.
Thanks to all,

Welcome to the board mag!

Here is my 2 cents worth. I never worry about trying to get my broadheads to fly exactly the same as my fieldpoints. Some people do and thats fine if it works for them. I truely believe that when you put a fixed bladed broadhead on the arrow, the flight characteristics will change slightly. I don't think that many people can argue that. If you can get the fieldpoints and broadheads to fly exactly the same, then you are making small compromises in in positive flight characteristics of the arrow.

I always tune my bow for each circumstance. During the off season, I tume for the field points, then about 8-10 weeks before the season, I tume for broadheads only and shoot fixed bladed broadheads exclusively.

Unless I am misunderstanding what you are saying, or there is a technique I was not aware of, the adjustments you are describing changes the nock height and centering of shaft.

The original problem you described is usually a result of a spine problem.

I concur with BobCo19-65.

I also agree. In September I start shooting only broadheads and sight in for them. Of course they have to be grouping well but I don't get conserned if they don't hit the same as the fieldpoints.

Would you think my 340 ICS is to light or to heavy. The chart has the 340 going to 80# at my draw length.
By way of the Easton tuning guide they say to get broadheads to impact with field points you move the rest and nock point in the opposite direction of the miss. I did this and the broadheads and field groups came together, but my arrow flight is not quite as good and my groups opened up a little.
I am sure the 340 are not to light, but my bow is maxed out so I can not add any weight to see if this helps.
I did try an ICS 400 with a broadhead and it also shot low and left just not as bad ( 3 inch left and 5 inches low ).

Thanks again for all your replies,

I am sorry, I can't help you. I shoot aluminum.

Once someone helps you out with the spine vs. tip weight and draw weight, I would paper tune (only) until everything is reading AOK.

Then I would adjust the bow and sight settings to meet the demands of your broadheads. You will not be hunting large game with a field-point.

365 Mag; I had a similiar problem this year. I shoot an ultratec w/ 28&quot; 3-60. I am maxed at 70#. My broadheads were low and rt. I moved up an arrow and that helped. The last thing that I did was check for fletch contact. I switched to feathers bc/ I couldn't clear my rest and now they are dead on. I don't really care for feathers but my bow is shooting awesome. Maybe you have some contact?

Their are no hard and fast rules when it comes to broadheads. The main goal is to get perfect flight and the best accuracy you can with your broadheads. I used to think both fieldpoints and broadheads had to shoot in the same place to have a tuned bow, and to be honest most of the time after tuning a bow, they do( with smaller heads anyway). I use 5&quot; feathers most of the time which helps. If I had to choose between both heads hitting together and better accuracy with the groups apart, I would choose accuracy everytime.
