well..when i started on the road to primitive..i read everything i could get my hands on about arrow
flight and such. i made lite ones, thick ones, skinny ones, heavy ones.....etc. I shot all out of the same bow....66lb reflex-deflex boo backed hickory, at a layered foam target. figured it shoud
be dense enough to provide resistance to the arrow. believe it or not...ALL arrows penetrated that
target the SAME amount, give or take a fraction. So
i figure whats most important is PROPER hunting
techniques and above all SHOT PLACEMENT.....my 2 cents....
