On saving the spent primers......I always save all of them.
I took a bunch of misc. trashed brass and spent primers to a local salvage yard.
The guy there asked what the primers were, I told him they were spent and if he wouldn't take them I'd keep them.
He pulled out his small pocket magnet and checked them and said "Brass is Brass"..!!! (It was listed as Cartridge Brass )
Don't remember how many pounds...YES Pounds of primers, but the total was NICE $$$$ This was about 3 years ago.
Had enough from that to buy more NEW primers and powder...
Even most 209 primers have a brass primer with a steel (carrier..can't remember true name right now )
But you must be very bored to separate the two....I've done it several times to waste some time.
Even made a small jig to set them on a single stage press and use a universal deprime die with.
It made it go very fast.
I know....I know...But sometimes you do dumb things in slack times.
