I recently saw somewhere on the net about surplus IMR 5010 powders breaking down and after I poked around today I found that there were a number of houses that burned down because of the breakdown and self combustion of this powder.

If you bought any of this powder back in the 2000s from Talon, Hi tech, GI Brass or else ware check it immediately. If you smell a strong ammonia or acidic smell ditch it immediately.

I found three jugs that were really bad. I checked and the ball powders like WC 820, 860, 872 do not seem to be affected.
