you confrim what has been said you need to search all over the country and be persistent just to find the amo you want to shoot. it used to be you could head to your local supplier and find it. not any more
How long have you been shooting?
I can remember not much more than a decade ago trying to find any selection of handgun ammunition other than Winchester Whitebox or American Eagle (or some crappy Centeur? sp), and if you were so lucky to find more than that like say any HP in any flavour, you paid through the nose for them.
Now everyone carries dozens of different brands in all types and loads, and some brands have several offerings, and there are several more big box stores as well that sell it by the boatload.
I was in P&D recently and there were no less than 6 different types of .357 magnum on the shelf (including Barnes? like when the hell did they start making loaded ammunition?), and I never seen any bare spots for any other calibers either.
And I have never seen so many bulk pack in ammunition cans and surplus ammunition in the past year.
Add to that online retailers like SFRC and Canada Ammo, I have never had it easier finding any ammunition, even during this so called "shortage".
So if there is a "shortage", it is not very noticeable, and your overall selection and options are much higher than it has ever been. Which when one of those dozen different choices is taken away, may seem like the end of the world to some, but to those of us shooting for years, it is still the best times ever for selection and ease of getting ammunition to feed our addiction.
