Perplexed.... arrow tuning

[superkodiak]

Guys,

 I am somewhat perplexed.  I am shooting a kwyk styk at 55# @ 28".  I shoot 30" 55/75 heavy hunters with the 50 grain inserts.  

Here is where I am really baffled.  I shot and tuned this bow and it was loving 250 grains up front.  This set up shot very well for me.

Fast forward to this week,I had some 125 grain heads laying around.  So, I figured I would give it a whirl.  I shot last night and arrows flew like darts and hit where I was aiming.  

So my question is:
is there a point where a bow and arrow setup could feasibly shoot two different arrow points (light and heavy) well based on the paradox of the arrow?  I am just baffled by this.

and I would like to blame it on cabin fever that we are having this conversation.... =)

Not sure of all the specs, such as how shelf is cut, string material, etc, but putting into a dynamic spine calculator  what we know about this setup, the 125's are about perfect and should fly better. 250 up front is way off according to the calculator. .

I've found that most bows will easily shoot a 50 grain weight difference.  This isn't rocket science.  Though there probably is one particular weight that is optimal, most bows, particularly those cut to and past center, are rather forgiving and will shoot a range of weights, spines, too, for that matter. Of course, when you change the point weight, you're changing the dynamic spine.

I can shoot 225,250,275 to 300 grains up front of my set up with almost no effect in point of impact.  The 300 grain points may fly a little to the left but its negligible.

With carbon arrows nothing much surprises me anymore.

What BAK said x10.

Field points yes. Broadheads, much more likely not.

When tipped with  field points the fletching can straighten out almost anything. Like Steve said broad heads (or bare shafts) might go different.

Once again the beauty, sheer joy and NO anxiety of wood arrows rears is its simplistic head.

The only thing that matters is actual results...my Kwyk Styk will actually shoot quite a wide range of spine and point weight rather well

If it works, your doing it right.

feathers, they fix almost everything until you put a big fixblade up front. try a bare shaft.
