Ah, the perennial "Short starter/loading block" argument....
So far, it seems all the documentation and research leads up to this: There are absolutely ZERO references to loading blocks from the 18th century, and there are plenty of period accounts of rifles and loading procedures. The "1757 A.N" loading block has a LOT of questions surrounding it... Loading blocks seem to have appeared around the middle of the 19th century. Same with short starters.
I have seen period references to cutting patches at the muzzle, however I believe standard procedure was to use pre cut patches. If I remember correctly, I think I read an account on how they would carry a bunch of pre cut patches strung on a thread at the corner of the patch, and they just jerked one off when they needed it. Another system that seemed to have a minor following was the use of patches tied/sewn around the ball, ready to go. I want to try this out, but haven't gotten around to it yet. There seem to be a FEW German rifles that have the patchbox cavity bored with several holes sized to hold the prepatched round balls, and the "Deschler rifle" (the super cool cherry stocked gun from the Northampton county region with the same type of box as "gun #42") has these holes in the patchbox cavity.
If I can't push the ball into the muzzle with my thumb, or at the most, with the butt of my knife, it is too tight. Smaller balls, thicker patches. :wink:
