Primers

[Sharpie]

Have these changed over the years? How old would these be? Can I expect identical performance compared to the new ones?

I'll take them. :-)

Ive used some pretty old primers. Never changed velocity.
They will be just fine
Primers when properly stored will last a long time

Same stuff, different box. I have some way older than those and they work just fine.

If you send the lot number to the manufacturer they will provide the date of manufacture.

I inherited a ton of old CIL primers and have been using them with no issues. I suspect that these are at least 30 years old, perhaps closer to 40.

The primers in the Red Mag box are from around 1995-2005. I am just finishing off some primers I bought from an estate sale that had their purchase dates recorded on them. 1960-1971. They are 60 years old and still work just fine.
