I thought I had plenty of 231. Then I double checked after reading this thread and I am almost out. Went to the gun store and they are out of pretty much all your standard pistol powders. So I called my dad back in North Dakota and he was able to find a couple pounds but he said the shelves were starting to look pretty bare there too. On the primer shelf(which was pretty bare as well), older boxes were marked at $35, but newer ones were marked at $58. Yikes.
I did find an old bottle of Trap 100 hiding in the back of my powder cabinet. I'm not finding much for load data on it, but I'll figure out something to use it in.
