I have 2 pounds of unopened IMR 3031, and 1 pound of unopened Hodgdon H380 that I would like to trade pound for pound of IMR 4350, IMR 4831, or Hodgdon H4350. If you would like to buy any of these powders, they are $70 each.  2 boxes of .22 ammo 500 round Remington also available to trade or sale. I live in Clarkdale, Az. Thanks
