Sabotloader - I particiated in those posts, though not the experiments. What I found this year, after paying close attention (and having a misfire on a big 8 pointer) was that my sidelock, loaded with Pyrodex, brought inside following a morning hunt, would fire when taken back out that evening for a hunt. When kept inside over the following night, the risk of misfire increased substantially. I don't recall whether either of your tests included a sidelock? Either way I should conduct my own experiment, but I'm not crazy about discharging a gun on the property unless something dies when I do. Thought this idea worth floating.
