What shelf depth is best for shooting off shelf.

[Bill Tell]

What is the preferred shelf depth for a bow?  I have a hoyt dorado with a shelf that is cut way past center and I need to build it out some.  I am tired of always having to guess at what spine to use because the bow is so far past center and I don't want to use a plunger.

Thanks in advance

start by bringing it out to center,anything past center will cause you the same spine problems. You didn't say what your draw weight is or what your arrow material is

[Bill Tell]

Oh sorry.

My draw weight is 53# and I am shooting two arrows.

1.  Grizzly stick Alaskans

2. 2117 Easton Aluminum

I usually bear shaft tune adjusting with different weight tips.

In a perfect world I would like to shoot 150 grains up front.

2117 are to stiff for that poundage more later I'm at work

I shoot bout the same,2016s at about 29"100grain tip for practice.hunting zwickey eskimo 125gr mounted on long aluminum adapter 40gr,shoots great.
