Update on my search for powder. Was on Midway's site and found 1# cans of H4350, was looking at 8# kegs of H4831SC. While I was looking around Midway updated their website to reveal that they no longer had the H4350 in stock so I immediately went to Midsouth's website because it was posted on here that they might have it in stock. Guess what I found on there, 1# cans of H1000 in stock, I hope it is not a mistake. I ordered 8#, didn't want to be a hog. I also went back to Midway's site and ordered an 8# keg of H4831SC. I have never used the H4831SC before, I hope it is the same as the H4831, says that it is. If you need either of these two powders, I hope this information is correct and that it helps someone on here. That farm supply store can keep their overpriced powder, LOL.
