This is an arrow from a compound bow....It would have zipped thru a deer....
I have killed a large number of pigs and they are tough....Smallish pigs..not so tough..big ones..yes....
Never shoot a large boar pig the same spot U would a whitetail..cause he will be gone....He will die..but nowhere close..and probably not leave a blood trail....
I have heard of folks shooting a pig with a 270..30-06..300 mag...just to have them run off....I myself shot 2 large boars with standard velocity 45-70 factory loads..in the shield....They both fell..then jumped up and were gone....I learned my lesson....They don't leave if shot in the neck....And U can even use a 223....I have seen pigs shot a dozen times with a 223 in the body tho and still running....I shoot larger calibers and/or heavier bullets....It increases my chances....U can see the shield on this large boar....U best take the neck or head shot....
