I have a friend who called and told me a sad story about his powder stash. We were leaving the hacienda for a business trip and were going through his town so I stopped by. This is his story. He had several pound cans stashed up high and out of the way from grand kids in a wood cabinet that could easily "breathe". He has central air and lives in west central Texas. He put the powder that he had carefully shopped for over the last 5-8 years up there when he found the all too few bargains that were available during the last political reign. One of the powders was a 1 pound can of VihtaVouri n133. He was reloading and ran out of his current pound can so went up on a ladder to see if had more up in his storage cabinet. He opened the door and was nearly knocked off the ladder by an acrid and pungent smell. He instantly realized that his powder had gone bad. Very upset he started pulling the cans out and putting them in a box. The inside of the cabinet showed the effects off heavy oxidation (rust) on the interior metal furniture, hinges, screws, latches. Further examination of the cans, mostly unopened, showed rust on the metal lids and any other exposed metal. The VihtaVouri powder had been opened about 3 years ago and a tiny bit used. He asked me if he should throw away the rest of the powder after showing me where he had poured the bad powder (it had chemically burned the grass where he sprinkled it). Then he let me smell the mostly empty aberrant can. It still had a very powerful acidic smell. I told him well lets look at your other powders. We went to the box and began to examine the other powders. Most all were unopened about three had been opened but the lids were screwed down tight. We checked and examined the opened ones the powder looked normal and had no smell. We looked at them through a lens and the grains looked normal. Most these were hot pistol powders. The unopened cans still had their seals intact. However the outside labels of most of the cans showed a yellow tinting from the noxious gases that had emanated from the n133 can and again the metal lids showed some rusting. We lit a little bit of each opened powder and they all went off with a an assured robust instant flaring.
Up near the cabinet there is a shelf and many metal objects that showed no corrosion so the corrosive gas/vapor whatever was contained in the cabinet. Down at floor level he keeps a couple of cans of powder that he is using under his reloading bench one of these is a can that is many years older than anything above. None of these show any type of deterioration. The house is under A/C in the summer and dry heat in the winter. He says he checks up there about once or twice a year and hadn't noticed anything. So should he keep his powder? Moral ?
Keep your powder dry amigos....STBE Harris
