What if one had a quantity of black tips that weren't 'pulls'?

As in never loaded? All to the good if you can put them on top of the right sort of propellant. The pulls I have are very clean, little or no marking.

Hi-Tech in St. Louis used to have all kinds of neat stuff, like .45 ACP and 5.56 blue tip. Sure wish I’d bought more when I had the chance.

I can tell you that blue tip .45 makes a rather spectacular shower of sparks.
