All of my old cans, some very old, were fine. The only exception is one fired and wouldn't stop once I released the trigger. Sprayed the whole can into my neighbors back yard - turned all the vegetation orange. I was glad they were not home and I really hope their dog didn't play in the orange patch, but I never heard anything and never confessed.... not proud but not in trouble either!

Someday maybe I'll also publicly discuss the couple times I inadvertently zapped myself with some UDAP (oops, guess I just did).... let's just say I would have 100% confidence in the product at either stopping a bear or clearing a riot out of a mall. Clear your schedule for an hour or two if you decide to replicate my experience.

** I feel the need to add this disclaimer that I truly think a direct shot of the good stuff (2%) to the nose/mouth could be very dangerous for a normal person let alone anyone with allergy or hypersensitivity. Not to be trifled with, or let loose in an enclosed space of any kind!!!

My grandma had a little 4” long key chain sized canister on her truck keys meant to defend her from muggers. After at least a dz years of being toted around she left her keys in her truck on a hot 95+ degree day and lucky for her I was the one to open the door first. It exploded and instantly I was cured of any thought of a life of crime! Good Lord the agony, 20+ years later my lungs still hurt when I think of it. My eyes are watering now. All that to say this, I’m sure glad I don’t hunt in grizz country, I’m think I’m more afraid of the dang spray that I would be of them!

I too use the old stuff for training our guides and guests. I’ve seen the really old stuff hardly work as described above. In addition to training the old stuff can be used to drive porcupines out from under the lodge or guest cabins and drive bats out of the eves. It’s not a permanent solution to the bats. The porcupines are shot when they come out.

I carry UDAP and the last can I bought had a 4 year expiration date We set off a can that was six years old and you didn't want to get downwind of that. If I'm a few miles from camp and getting dark I'm not going to second guess the guys who sell this, cheap insurance I think.

A buddy of mine told me about a local bike shop that was giving a demonstration using an old, expired canister in the parking lot. Within 5 minutes, people started pouring out of every little store in the strip mall. Seems it was still potent enough when it got sucked into the ventilation system...

Since we are talking bear spray. Another thing I learned from the factory rep was that in order for the propellent to work well, the canister has to be about 50 degrees Fahrenheit or warmer,,,well not lay it on the dashboard warm.

I suspect pretty strongly that the propellent is iso butane. The vapor pressure at 50 degrees would be 35ish psi. At 80 degrees it would be around 60psi. Before my conversation with him I never gave that a thought. I routinely hung a canister on the saddle of my horse,, right in easy reach. Now I put it in a holster that is inside my coat.
So what would the spray effectiveness be at 10 degrees? open day of rifle I usually carry a can but dont bother late season

I doubt it would be very good. Likely like an old man standing at a urinal.

Once my cans are past the expiration date I use them to practice, for myself, my wife, and when the kids or family comes out. Our life is worth spending another $40 for 2 cans that are new.

My .44 will always be my backup, for me personally it goes bear spray first, gun second. We've had to do it once and glad we didn't shoot the sow w/cub, the spray was effective.
