It is funny how the Gun-Run is different, depending on where you live. I live in a fairly rural part of the Shenandoah Valley, and often stop by a small gunshop in a little town. The owner told me that during the past 4 months, every .38 revolver he had (or got), new or used, was snapped up immediately, as well as all .38 ammo.
As for magnum revolver ammo, such as .357 and .44 mag, he doesn't really have much problem keeping it on the shelves. You also have to remember that almost everyone in this county is poor, so not many could afford to run in and buy lots of boxes of mag ammo at $26.00 a box and up.
He said that his big supply problem is that he can't get any .32 auto or .380 auto, and that he has trouble getting the .22 ammo in bricks. The .22 ammo goes out the door almost immediately. He now says that he will not sell more than one brick of .22 to any customer. (He thinks that it is not fair that so many people are hording, and his other customers can't find any at all.)
He does not stock military ammo. This is groundhog country, so all of the .223 he sells is soft-point varmint ammo. He had plenty.
Also, no problem getting regular hunting ammo, in any of the deer calibers, including .308 Winchester.
