Back in the paleothic period, I cleaned out Brock's Army Navy of their compete Fiocchi inventory. At least 15k SPP and 3k SR primers with zero issues. BTW I paid $8.99/1K....🙄
Absolutely not. Billy-Joe Jim Bob could stuff as much blue dot as that 9mm case could hold. I like my fingers and hands JUST the way they are. I would smile and be gracious and pull it down for components, and have a bon fire with the powder.
I started with a RCBS Rock Chucker in 1990. I learned by trial and error and error...the finer points of reloading. In 1992 I bought a Dillon RL550B for the outrageous sum of $295. I will be running off some 9mm later today on that same machine. In that time, I've had one powder measure...

This for the past 30 years. Mine is, of course, the incarnation of this from 1991. The beam can't hide issues, and properly zeroed and used,...Zero problems with zero!
Currently a safety deposit box might be best...
I've kept primers on a shelf in non-conditioned air shop for 30 years with no issues. In conditioned space would be luxurious for them!
Only if enjoy frustration. I had a Piggyback II in the early 90's and I couldn't make 50 rounds without it screwing up. I bought a Dillon and threw it as far as I could. Junk it. Trust me.
