LOL at "BS". The Ashby studies are all the validation on the 650 grain bone breaking threshold you will need. "NEED" ??? ll damn sure bet you there are a few that wished they had t when they came home empty handed if only they would have had the proper setup to get the job done. Nobody ever penetrated to deep with an arrow but many dont penetrate deep enough. As far as me knowing EVERYTHING about bowhunting. Yes. well yes I do.
And I dont see why you are getting so upset and emotional over this. Settle down. No need for this to get you so animated.
