The stuff came out in 1976, went in to full distribution in 1978 and very likely didn't reach Waco, Texas until 79. That's the way things happen around here. In any case, This can came from the first shipment to reach Waco. Johnny Bates tried it out and, learing that it was no easier to clean up than black powder, put most of the can in his garage and forgot about it. It has been there ever since being exposed to temperatures ranging from minus 5 to Plus 110 and whatever moisture and humidity could get around the stopper ( little or none) Bad storage conditions.

It had the usual easily dispersed clumps that happen in older pyrodex but appeard usable. Experts- many of whom have very large genital organs and even bigger mouths, have declared that Pyrodex will become enert in a short time. We didn't know what to expect.

The difference between the two strings of six rounds could be explained by the randomness of small numbers or by routine lot to lot variation-or the 'dex might have gotten weaker over the decades. Interesting though that it doesn't seem to have lost any consistency.

After the chronographing, I loaded my LePage Target pistol with the old stuff and fired one round duelist from 60 feet and another from 25 yards. They hit about an inch and a half apart on a peach can.

Interesting results. I always heard that Pyrodex deteriorated over time, maybe it's an urban legend. Certainly the storage conditions you described were worst possible case that would destroy most propellents.
