Interesting thread!my friend used to guide in northern manitoba for years and swears to have seen more game being lost with a rifle then a bow !his theory was if an animal is shot with a gun,between the loud bang and precussion felt ,gets the adrenilne spiking!on the other hand animals shot with a bow will twitch ,run a few yards and start to eat again,bleed out and fall over.on another note ,a compound guy I know shot a pronghorn at 20 yards with a mechincal broad head and Just bounced off cuz all the energy was obsorbed by those switch blades hitting bone.he now uses trad broadhead with just legal 7/8" cutting width with success.
