To make things worse the cans can sit for years in a case and leak the propellant.My brother in law got attacked by a mean black bear that ran many folks out of the area but brother in law says I got bear spray so I'm no scared.The bear attacked,got within 5 feet or so and brother in law pushed the button and it went,Poof and done!It got worse!The wind blew the small poof of spray back into brother in law's face!He fell to the ground screaming and the bear got scared and ran.So I told brother in law,throw the bear spray away and just start screaming!The thing I don't like about bear spray it's just a deterrent if a bear is mad and adrenaline flowing I wouldn't want to trust a spray.
I've heard of and seen a few videos were people bought bear spray and it wouldn't spray from old cans to new ones.
Think I would rely on a primer to go off instead of bear spray.
Nope,I would rather rely on a proven method!44 mag or 10 mm!
