Hey Salty, neat hearing you were using a drop tube to load with.
I used to make a lot of those for BPCR shooters to load their brass with, but never did make one for muzzleloaders, although we did offer them in our catalog.
Wish I still had a metal lathe, I would probably still make some. Just thinking it would be fun to see if I could turn the tip of the tube into the funnel top instead of soldering a brass funnel onto it?
