Rangeball, If you' re looking to keep your arrow in
the bird you might consider using a adder point behind
your BH. It will stop your arrow
and inflict a lot
of damage. I,too, believe your blades should be razor
sharp.
Going one better than the adder point, is the Rocket
Sledgehammer

...3 1/2" cut. This baby puts a hurtin'
on turkeys[:-].
