Do they?
(assuming they are stored well)
I've shot ammo from the 60's......
( 30-06 )
Really depends on how they've been treated. You already own them, load a few and shoot them. If you can run them across a chronograph and compare to an identical load with fresh primers.End of guesswork.
Shelf life is only as long as you keep them on the shelf.
The only modern-style primers that I have ever known to have gone bad were either stored above 120 degrees F for years, exposed to oil for months, or stored damp or underwater.
It's not like they're made with ammonium chlorate (absorbs water) or mercury fulminate (eventually breaks down from oxygen exposure, if I remember right).
You should be fine but if you look at them and see oxidization on the metal or other discoloration, then they may have suffered from long term storage. In any case, they'll likely still work regardless.
I am using some LR BR primers in the same type of box. I know they are at least from the late 70's. My dad bought them when the store was out of regular LR primers. We only used them when we were trying to get smaller groups from our .30-06s. I am loading them up now in .308 to get rid of them and start on some Federal 210m. They are still fine and shoot small groups.
I can't speak to your primer directly, but I just finished using up a couple of thousand large pistol primers in my 45 ACP that my father in law had stored in his Houston garage since the late 1950s they functioned fine (even though they had NOT been stored in climate controlled conditions).
There are still probabley 7,000 small rifle and small rifle magnum primers sitting there waiting for me to test and use I beleive that they will also be fine.

I remember the box. Seventies sounds right. </div></div>
Pretty much. Primers, if stored right, can last a long long time. I always store mine in waterproof ammo cans. I never know when I'll pick up the next project, so if it's awhile, they can get affected by humidity.
