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.
Freedom is not free. The best of us always leave too soon.
