Why? I believe theory, as often happens, its over riding Real world hunting results.
Every post I have reads something like: I shot the critter, he died quick with a great blood trial, which really was not needed because it died so fast. However, looking at the tip of the Woodsman after picking it up from the ground after a complete pass thru, it had a slight bend in it. This might affect penetration. What should I do?
My advise is: NOTHING! When I used them (switched to Eclipse 4 blades), I used both types of tips and had 80% complete pass thru's on deer with both type tips using a selfbow. It its my belief that a properly tuned arrow has much more effect on penetration, and therefore lethality, then rather it has a "tanto" tip.
Being able to place the arrow where it should go is more important then
As Tim Ott once told me, "Walt, quit worrying about it, dead its dead!
