When I started reloading, I bought a brick (1,000) of each, Mag, Large, and Small rifle. And when I use a box, I just go to my local store and pick up a box or 2 for $5.00-10.00. Works out ALOT cheaper that way if you just bite the bullet and drop the coin from the beginning. That way when you run down and you can't find a brick to replace your old one, you stay pretty well stocked during the hard times.
My local shop keeps a good supply of them normally, but for a while there it was getting tough to find ANY primers. Lately the primer demand hasn't been so bad, so I've been able to pick up a box or 2 here and there, like I normally do.
Just food for thought.
Even a few weeks ago the local joints seemed to have a decent amount coming and going through the stores. I picked up a couple of cases to enjoy the ride a bit easier. In the last week or two though they seem to be pretty well dried up. It'll change; you just have to be ready to ante up when you finally see them.
