Are snap caps not meant to be cycled through the magazine of a pump shotgun, just like a shot shell? I tried to begin such a process with Traditions brand snap caps. The first snap cap jammed (and remains stuck) in the mouth of the magazine, and so far I have not been able to dislodge it. I'm thinking about pushing a plastic tipped cleaning rod thourgh the other end to push the snap cap backwards out of the magazine mouth; but, since this demonstrates that my nom de plume is still apropos, I will await words of wisdom from those who are generous enough to offer them.
