I've been finding powders at the local gun shows. I'm only 20 minutes away, and there is usually one every couple of months. There were 2 in December.
At the last show, I picked up a pound each of Bullseye, Longshot, HS-6, Silhouette, and WSF. All but the Bullseye are new to me, I've been trying out different powders to see what works and what I will buy in the future. I'm over 20 different pistol powders now, and still looking for more.
There was plenty of Titegroup there, and also BE-86 for $20/lbs. Didn't buy those since I have plenty for now.
Still looking for AA#2 and #5, Solo1000, Nitro100, Blue-Dot, Zip, and TrueBlue.
There are a couple of vendors at the shows that I like to deal with. I can call/email them or go to their websites to see what they have. At the last show, I had already paid for the items online and picked them up at the show, so no hazmat fee for me.
