I did see new signs in the ammunition section. The usual 100 round, or one bulk box, limit of rimfire. But they now limit centerfire purchases, too.
100 rounds of handgun ammo, 60 rounds of rifle, 10 box limit of shotgun shells. Or one bulk package of either.
The clerk said the policy changed because there have been several instances of people coming into various SW stores and buying huge quantities, like 50 or more bricks at a time. Some people bought every box of a particular caliber.
The clerk wouldn't commit a guess as to the reason. I'm hoping it isn't the beginning of the ammo "problem" spreading to all ammo..........

Also signs limiting reloading components, too. I don't remember them exactly. I think it was one can on powder. Limits on bullets, brass, and primers were all in the low hundreds, IIRC.
