Just stumbled across a bunch of primers I've forgot I owned & had for years (probably about 25-30 years). Boxes of Large/Small, Rifle & Pistol of the CCI & Federal variety.
What is the general consensus (if any) on using NOS primers?? They have always been stored indoors but can't confirm the heat/cold/humidity variants since at times I have had household goods stored in warehouses during active duty moves.
I assume I could simply seat some up in empty cases to see if they light off.
Any members here ever use "vintage" primers?
Comments, concerns?
