I think yes. Actually, I was at a regional sporting goods store the other day asking about .22 (the shelves appeared to be empty) and he told me he didn't have any ammo, but he offered me a deal on a 10/22, he said the prices were marked down because no one wanted to buy a gun they couldn't find ammo for.
Personally, I shot myself out of .22 last time I went to the range. As of right now I'm considering buying an airsoft gun; at least ill get trigger time that way. As it stands the only ammo that seems to be well in stock is shotgun ammo. Which is ok for me since I have a Mossy 500. Thank god I didn't trade it for a that p95 last fall; 9MM is impossible to find around here too.
