Nobelsport 209 primers in 10,000 count boxes

[Cold Spring]

I wouldn't dump a large quantity of ANY 209 primer into a bag or bin and try to fill a 10 x 10 tray by putting the empty tray inside and hand moving the primers or shaking the container. Primers are separated in the commercial tray for a reason and the open (anvil) end is separated from the adjacent primer by a plastic barrier. I'm thinking a sympathetic detonation of all the bulk primers in a bag or container is possible - remote possibility as that may be - by static electricity, a loose anvil, primer mix that wasn't properly loaded, or whatever.

Lets think about this for a minute. When you load a MEC for instance, the primer tray drops a primer like 8 inches down a tube and it drops and lands under its own weight. It also takes a hammer strike to make it go off in a shotgun. The most sensitive part of reloading is pressing the primer in a shell, albeit its only one at a time. Putting a card in a bin and my hand putting primers in the holes isn't going to set it off. The box that the primers came in had like 60 of them all loose clacking about in shipping. I live in Hawaii, Static doesn't live here, but your mileage may vary upon location. Like I said your invention is nice and its definitely more organized, I just do it another way.
