Look - I don't care what you guys think or say, I've shot enough deer to know that if I hit a broadside buck with a 1-1/16" diameter Muzzy - doesn't matter if it's as dull as a butter knife orscalpel sharp-that deer is leaving with a 1-1/16" hole on both sides, lungs demolished, and it isn't going 100 yards.
I mean really, an airplane propeller isn't razor sharp - but go ahead and stick your hand in it and see what happens. There is more to cutting than sharpness. Speed and Pressure are required. Duller blades need more speed and pressure. If you're shooting 90# KE - you could hunt deer with practice points if you so desired. It's a 150# deer, not a 5 ton elephant.
No disrespect intended, but:
1. no one, and I mean no one, can guarantee to always get a double lung hit...we're talking about real world variables.
2. what you are saying is true...a rock can be theoretically be thrown hard enough to kill a deer. Is that responsible hunting? Does it insure a quick and humane kill?
