I used
http://www.tntreloading.com for the 1st time a couple of weeks ago. Great prices, and they did match the price on the site.
I got 16# of powder delivered to my door via Fed-X for $12 per pound. The same power locally would have cost me $16 per pound, plus tax, plus a 90 mile round trip to pick it up.
Good Luck...
Joe
