The reason we wear caps on the range is to keep brass from hitting our faces. Especially to avoid having brass get behind your glasses and burn your face. I forgot to wear my cap two days ago and a piece of .22 brass got behind my glasses.
As you might imagine, it was painful. Fortunately, I maintained my composure and didn’t muzzle my friend who was with me. Wear your safety equipment, including a cap. Nonetheless, be mentally prepared to get burned by brass, maintain your composure and your muzzle discipline.

Ouch; I’d bet that everyone who reads your blog has a scar like that somewhere. Mine was from .22 brass also; nasty little suckers.
.22 brass can work its way into places centerfire brass won’t fit.
I am sorry you got burned but happy the outcome was not worse. We added BALL CAP to our range “Gear List” several years ago. It is the #1 item that gets ignored. We now carry extra ball caps to the range w us so if a student forgets, we have ya covered. Thanks for posting this and we will be sharing this often as a reminder.
This is one reason I prefer to shoot with my safety glasses rather than regular glasses. Good ones have shields all around the lens/frame openings to the face.
Mr. Claude Werner …. I would like to include this photo in my training curriculum as a demonstration on the value of wearing a billed cap. Do I have your permission to use the photo, with appropriate credit to you?
Certainly.
