Funny--I thought tracer ammo just had a bit of magnesium or phosphorus tacked to the base of the bullet. (Whatever metal burns when heated enough).

Didn't think that had a shelf life any different or shorter than that of the chemicals in the primer or gunpowder.

But then again, I found that the military assigns a shelf life to tires--and out the door they go once that life is reached, regardless if they have been used or not. I'm fine with that--got some skookum tires for my forwarder for 100$ each.



Tracer rounds are a blast...but I guess they can be a heck of a fire hazard in dry countryside.
