I have not had to buy primers in 3..4 years. Still have 7000 in bricks(2ea sm pistol, 1lg pistol, 1 sm magnum pistol,2 small rifle, 1lg rifle) , 7 trays of lg rifle magnums, and many trays of assorted. But, I also have quite a bit of brass that only needs powder and bullets. I decap and size, clean, prime, and box them in 100ct lots. Both 9x19 and .223 are heavy that way.
