Just my 2 cents on this subject.
1. Powder is hard to find, but not impossible. I have found some powder, not a lot , but at my local Gander Mtn., Cabela's, Scheels All Sport stores I have found some. Some stores don't have it on the shelf, its in the back and I had to ask for it. My best sources have been small LGS in out of the way places that I found as I travel around. My local hometown gun store has ordered some for me and its taken several months but he coming through.
2. It is not a conspiracy, There is a huge demand for ammunition and powder. I read and article in a outdoor paper that I came across in the barber shop. It was concerning the funds that the state gets from the Pitman - Robertson act that puts a federal tax on all guns and ammunition and gun related accessories sold. In turn this money collected is distributed to the states for conservation projects and the likes. The last 2 years there has been a 43% increase in the amount of funds coming back to the state. That is a direct correlation to the amount of guns and ammo that has been sold to the public in the last two years. In retrospect, there is another act that applies a simalar fed tax to boats, bait and fishing equipment. That fund is not growing like the P-R fund.
3. On one of these internet forums just lately a post from some one in Texas was showing off his stash of pistol powder that amounted to 50#, which was the maximum amount that he was allowed to store, per city ordinances, in his house. He went on to add that he was inventorying it because he had similar stashes are friends houses also. He laid claim that he shot over 16,697 rounds every year for the last 5 years. When the hell does this guy go to work, if he is reloading and shooting that much and like the rest of us he should have to search for powder like the rest of us. That guy is one of our own shooting community members who I think can't pass the smell test.
4. In 2012 it was reported that there were enough guns sold to the public in the USA to outfit the entire chinese army and the army of india. That is a significant number, and if the manufacturers of ammunition are going to keep up with feeding ammo to all those additional guns they are going to have to expand. Even Steve Hornaday's statements at the shot show informed us of that problem and risks involved. Demand from the shooting community is what has caused this shortage. And I wouldn't expect the prices to come down very much as the demand is gets satisfied. Too many have shown and proven that the price will be paid to get the goods, just like food, gasoline and beer.
