There's a gun show about fifty miles away next weekend. Maybe I'll find something there.
FWIW, I noticed that the price sticker is still on my last bottle of 231. I paid $26.95 for it. I dread to see what another bottle will cost if I find any.
Thanks for the replies.
Since most of those are shotgun powders, you might try calling your local trap/skeet type clubs - especially if they have a pro shop - they might have one of those powders sitting on the shelf
