Quickest kill

[Pushbutton2]

My first comment isn't archery related. But is shot placement related.

Last year I shot a pig with my .223 using a 55 grain VMax.
He was about 50 yards.Bullet went in on right side behind last rib didn't see an exit. He ran 78 yds. I cut him open to see what kind of damage the bullet did.
Center punched his heart.
