Tuning two bows to same point of impact.

[Apex Predator]

I have two bows that I like very much.  One is a 50s style recurve and the other is a slight R/D longbow.  They both have the same trajectory.  I shoot three under with a high anchor.  My problem is switching back and forth between the two.  The grips are very similar.  I would really like both to hit in the same spot.  I am a new gap shooter, that has discovered much greater accuracy since trying this method.  For my recurve I hold 12" low at 15 yards or less, and 6" low at 20 yards.  My point on distance is about 23 yards.  When shooting my longbow I hold 6" low at 15 yards or less, and point on at 20 yards.  I like to shoot whichever one appeals to me at the time, but have difficulty getting into an instinctive groove swapping back and forth.  Both of these bow grips puts the arrow pass right over my hand.  Any thoughts on how to make my recurve hit like my longbow?

Shoot a heavier arrow from the recurve

[Apex Predator]

They have the same trajectory now, and I want to keep it that way.  The longbow draws 6# heavier.  Point of impact is just different with the same sight picture.

[vermonster13]

If point of impact is different then they don't have the same trajectory.

[Apex Predator]

I haven't chronographed them, but they have the same amount of drop at all ranges.  Maybe I don't understand trajectory as well as I thought.  If you plotted both arrow paths on graph paper they would be perfect matches.  To me that means same trajectory.

[vermonster13]

If the gap is six inches lower for the recurve, then it is a bit faster. You need to either shoot a lighter arrow from the LB or heavier from the RC to make the gaps match up.

[Apex Predator]

The gap from 0-20 yards is the same for both bows.

[vermonster13]

That is not what you have written up above.

[Apex Predator]

Maybe I wrote it wrong, but both drop 6" out to 20 yards.  Can you help me David?  I was thinking of putting velcro on one of the shelfs to raise the arrow more above my hand.  Which one to change though?  Right now they both have leather.

SO is the gap 12" at 15 or less for the RC and 6" for the LB, or are they the same? Is point on 20 for the LB and 23 for the RC?

12" at 15 or less for the RC and 6" for the LB

Is point on 20 for the LB and 23 for the RC?

 Yes.  If I hold point on at 15 yards with each bow the recurve group will be 12" high and the longbow group will be 6" high.  If I hold point on at 20 yards the recurve group will be 6" high and the longbow group will be dead on.  Clear as mud huh?

[Apex Predator]

I hope you aren't running out of patience with me.  I value your opinion, and you are the only one to touch this one.  I must have confused everyone!

[vermonster13]

Then the recurve is faster and what I said above holds true.

[ks_stickbow]

you could try messing with the nock point, but your risking loosing your tuning, but some bows are more tollerant then others.

[vermonster13]

No matter what you do, the recurve is eventually going to hit higher again. But you should be able to get them close enough for 20-25 and in.

For me, when I try to use my arrow as a reference, a longer arrow will bring my groups down some.
