I am shooting my 145 gr field tips quite well. When I put broadheads on from 132 - 170 gr my arrows seems to drop tip down / nock high almost every time. I have shot 2 blade, 3 blade, and 4 blade. Should I try to adjust my nock point.? Can't seem to figure this one out...Scott

Nock high means take your nock down but it should be the same with field points. Hmm I'm interested in what it could be too, hopefully someone with a little more knowledge can help you out

Broadheads magnify tuning errors that may not show up with field points. Just make sure your broadheads spin true, then adjust nock point.

what's your complete set up and draw length? as others said what nock height?

What Pistolpete said  Lower your knocking point till the arrow shoots straight. after the broad head shoots good try a field tip. also brace hight or nock tightness on string can cause trouble.

Highly suspect that the issue is not at all associated with the broadhead's themselves.

Would be resolved to believe that the poor flight is isolated to an arrow tuning issue.

X2 Broadheads tend to magnify any tuning issues. Nock position is certainly one of them.

Have you bare shaft tunned?

Do they hit with field points using feathers? If so I wouldn't worry about it assuming you have bare shaft tuned.

You do not need our permission to try something as simple as lowering the nocking point

It definitely would seem like your nock point could be to high.

Assuming that it's a tunning issue and not a shooting error, nock high could mean that the nocking point is too high...or it could be that the arrow is bouncing off the shelf.

So, the nocking point might actually be too low.

I start with my nocking point way high so I know it can't be too low and work down from there.

Some also find that using two nocking points help (one above the arrow and one below.

Going with Redshaft. I am a big fan of bare shaft tuning.  It requires good form but shows all tuning errors that field points all and fletching correct.
It will also show you form errors as inconsistent arrow flight.

Move the nock point a little at a time, if it gets worse you went the wrong way, easy thing to try and can always put it back.

DDave,

come on man.  He was asking for some help, not a smart alec answer.  


Back to the OP.  I would bet that your nocking point is too high.  Field tips will fly where ever your feathers take them.  When you put a broadhead(rudder) on the front of the arrow, the front becomes the steering that leads the feathers where as with a field tip, the feathers do the steering.  

Try to move your nock down 1/16 of an inch or something and see what happens.  If it gets worse, try it a little higher than originally.  There is a possibility that when moving the nocking height, you will see some changes in the spine as well.  I always get my nocking height right first and then worry about spine, but that is just me.
