Doesn't anyone here check Grafs? They just got in 85 boxes of 7.62x39 primers. At the time all I could afford were a box of 1000, think they sold out in 2 days. The 5000 boxes sold out in less than a week. Maybe you should talk to them.
Use my dremel with a very small drill bit, hooked very small screwdriver, can take out a primer in 5 sec. Not as messy as the water method.
