Being an outdoor writer, I have contacts at many of the shooting sports suppliers. Hodgdon's tells me that several powders that can only be manufactured using older methods that require several days more plant time than ones using the newer methodology have been discontinued or will be for 2015.
Among them are all the IMR SR powders, production of which as already ceased. If you want any, find it now for there is no more coming. PB is another casualty as is IMR 4007SSC and Winchester AA Lite.
Since learning that, I have been able to lay my hands on three pounds of 4756 and two of 4007SSC. W231 is coming - in fact, I was told during the third week of July that a shipment was expected during the last week of July that would be repackaged and distributed during the first or second week of August, so keep your local shop owner apprised of your wants. Meanwhile, AutoComp is readily available and a little more of it will do everything 231 will and then some. I've found it to even be cleaner-burning than 231 and more accurate in my .38 Super and .45ACPs.
Truthfully, there aren't many powders that are impossible to find in local shops around here. You just have to seek out those shops as some are well hidden. There might even be a shop right around the corner or down the street that you don't know is there. I mean that and as proof, I recently found one strictly by accident that I'll guarantee has been there since 1950 without even some of its neighbors knowing about it.
About four months ago, I wanted to buy a Smith & Wesson E-series Model 1911Sc. None of the local shops I frequent are S&W stocking dealers and had that model in stock but I was able to find a new one on GunBroker.com that was being sold for a fair price by a dealer in a city about 45 miles from our home. I hit the auction's "Buy Now" button, put the shop's address in my GPS and pointed my vehicle in that direction.
When Mr. Garmin told me I had arrived, I was in front of a small center-city corner store-type pharmacy. After confirming the address, I entered and very tentatively told the older lady behind the counter that I was pretty sure I was supposed to pick up a gun there. "Oh yes," she said and called for "Allie" who appeared from a back room and invited me to follow her there. Now I was in a room where a third lady was filling prescriptions and Allie handed me my gun's box. I looked around, asked if they did a lot of gun business and learned that mine was the 15th gun to leave the shop so far that day, all through Internet sales! I stood right beside the lady putting pills in bottles while I filled out my ATA Form 4473 and Pennsylvania State Police handgun paperwork.
Allie then led me into yet another room absolutely stacked with handgun boxes and asked me what kind of guns I was interested in. When I told her that one of my weaknesses is 25 to 40 year-old Smith & Wesson revolvers, she said it was too bad her father, who owns the business, wasn't home because he has over 5,000 guns in his climate-controlled basement and something on the order of 3,500 of them are S&Ws dating back to the old "Lemon Squeezers."
When I wondered out loud why I had never heard about their shop, she told me that they cannot post any gun-related signs or advertise their gun shop because it is located within a school zone and the city has an ordinance prohibiting anything promoting guns or gun-related signs and advertising in those areas. So just because you think there aren't any gun shops nearby, that in fact may not be the case!
Then the other day, I found myself following an SUV with advertising for a local gun shop I never heard of on its rear window. A call to the number shown confirmed it was in fact in business so you never know where you'll find another shop.
Everybody shops at the "big box" gun shops like Gander Mountain, Bass Pro Shop and Cabela's, so they never seem to have anything. Your small local shop owners should be some of your best friends.
