A really good hunter told me about a buck he shot that he forgot to fill his quiver for. He took 2 arrows when the quiver held 5...
Shot one, hit liver.
Trailed the deer after a while, found it bedded down, shot second arrow and missed. Buck ran off.
Found buck again, still alive and tangled in a mess of briars, ripping himself to shreds. Without a third arrow he couldn’t do anything for the buck, so after giving more time and calling his buddy, who brought his own bow and a full quiver, they were finally able to dispatch the deer and end its struggle.
I heard this story before I bought my first hunting license. I always subscribe to 2=1, 1=0 in this and many things. My quiver holds 6, so I have 4 broadheads and 2 adders for small game.
