I have been involved in tactical shooting for a while.

One course involves shooting at a card board mannequin . The mannequin has a ball cap held on to the head with 2 staples.

Shots fired are with 9 MM, .40 cal, & .45 cal . All hand guns.

.223 and 12 G. slug long guns.

EVERY SHOT that hits the tip of the brim is deflected. The cap is NEVER knocked off. Amazing !

You wouldn't believe it without seeing it. I didn't.

Also , a lot of head shots strike too low ….due to trying to shoot under the ball cap.

I also hunt and have shot more than a few deer. A bud on a Birch tree will deflect your shot.
