Good info and it correlates with my experience.

I usually take my flares up to my dad's country place and fire them
off in the winter. Last winter we had a few really old ones, from the
mid 80's, most of which fired but the flare did not ignite. One of
them, however had the opposite problem, it did not fire but the flare
ignited in the barrel. That was fun!!! Drop that gun and run!!

The other thing that struck me was how much higher the hand helds
wentt and how much longer the burn time was when compared to the Orion
12 gauge flares.

I would recommend firing expired flares if you can. It's good
practice should you ever need to fire them in earnest.

Yesterday, I fired 4 expired "Orion" 12 guage flares. All four fired
but only one worked right. Results

expiration year results
1990 Worked correctly
1995 Fired but failed to ignite flare
1998 Fired and flare ignited but only went to 50'
altitude
1998 Fired but flare failed to ignite

2 Current flares: Fired and worked correctly.

Two years ago, on a very rainy New Yrs, I fired a bunch of expired
flares and all fired. However, the rain was so intense that I was
unable to determine if the flares ignited.

This test tells me that although old flares ussually fire, they do not
work well.
