Most of the 22 varity were called low velocity when they were sold.

Meaning

the power moves a rod that actually hits the "pin". There were some high
velocity guns made in the .22 caliber.
Pins and loads can be acquired in a lot of places. like any ammo the stuff
is not good forever.
I have some 3-5 year old yellow loads that I used recently. 30% of the

box

were duds.



I can't say how long the stud gun loads last, but regular gun ammo is good
almost forever if stored in a place that does not get too hot. I have some
reloads I made myself that are over 30 years old and some comercial shotgun
shells that are 40 years old and it is just as good today as it was when
first made. Even the military stuff left from WW2 is still good.
The stud gun loads may not last because they seem to be open and just
crimped in the end instead of being almost air tight.


I agree.

I don't know how well the the fastener guns loads
are sealed, probably like blanks, but I assume
that the loads are not sealed well. And if they
don't last long then they are being contaminated
most likely with oil, probably by people that
don't know oil will kill them.

But ammo is sealed well, some water proofed, and
as long as it isn't destroyed by water or oil, it
last practically forever.
