Broadheads

[tommyjohnston]

So I started archery shooting at the beginning of this year.  I just picked up a new to me Mathews Reezen 7.0 LH bow.  I have put about 150 shots through it.   I am shooting Beman 340 grain diameter arrows (came with the setup).  I am shooting 100 grain field points.  I am getting 2 inch groups right about where I put the sights.  Then I decided to shoot a couple broadheads on the same arrows also in 100 grain.  I am aiming for the same spot as the field points but they are hitting the target 3 inches to the left.  Same height of where I am aiming but way left.  What could be my problem?  They are grouping within 2 inches way left.  The broadheads are NAP thunderheads.

Move the rest 1/64" to the right and shoot both broadheads and field points.  They'll be closer together.  Keep moving rest right a tiny bit at a time, and they will both start grouping together, and then you can move your sight to where the group is in the middle.

If moving the rest in tiny increments doesn't solve it then it's likely you're torquing the bow ever so slightly.

I had a problem with broadheads a couple of years ago & really had to work on my form to get them to shoot right. I was really glad I didn't start adjusting my bow etc.   I would spin test your arrows with the broadheads first & get two perfect spinners at least.  Then I would shoot those over a couple of days to make certain it is the bow. Then I would move the rest. Like I said I have wanted to start adjusting my rest, sights etc to correct but was very happy I took my time & made sure of everything else first.  Mike

If my form is ok when I shoot with the field points how is it changing with the broadheads?

[jechicdr]

The form is the same, but field tips are more forgiving of form errors and tend to correct themselves faster.

[JLS]

Because (if your form is perfect), your arrows are not coming off of your bow perfectly straight.  In this case, your arrows have the tip slightly to the left, and the broadhead is then "steering" them to the left before the fletching can stabilize the arrow.  Hence the POI is left.  If your nock was high, the arrows with BHs would hit low.  Nock low, BHs would hit high.  Field points don't make the arrow plane, or steer it like a BH does.

Make sense?

Have you paper tuned your bow lately?
Broad heads and field points should hit the same with a tuned bow.

Huntersfriend.Com has good write ups

I have not paper tuned it personally.  I need to get it down to The shop and have this done ASAP.  The bow is tuned.  It's tuned for a 6'6" guy and im 6'.  Big difference!

[Button Nubbs]

Paper tuning is nowhere near the end all be all in tuning. As a matter of fact it is the first step. I strongly suggest you do as todd_id says. You say the bow is "tuned" for a guy who is 6'6" and your 6'? Has the draw length been changed?

[tommyjohnston]

Yes a shorter cam had to be put on.

Maybe I'm wrong, but these are not legal in WA.  Correct?
