wabi, today I was shooting my Ultra Mag. I had carefully patched the bore following a prior shot, carefully measured my charge in the U-View, used a brass funnel to pour to the bore, then did my usual number of taps to settle the powder. It was then I noticed the piece of cap hung under the plunger. In trying to free that bit of copper, I pointed the bore toward the ground...

So I just fired off what was left of the powder charge and started over.
