3031 is a great powder, never goes out of style for old timers. I go to two gunshows locally every year. There are 2 to 3 dealers I look for at those shows. They generally have some great obsolete loading components the black plastic gun guys don't want. Last show I managed to find 85 primmed 25 20ss for $2 each. He apologized for the price and I told him I considered $2 each far better than the $6 I see them sell for on Gunbroken. I ended up spending $300 at his table!
