OK, so -- now that I think I have the hang of the picture thing -- I'll take it from the top...
First of all, here are a couple shots of my rifle.
Althought I've had her for a while, I am only now just getting to know her a little. My last range session involved shooting two 5-shot groups at my local club (Library Sportsmen's Association in Library, PA -- just south of Pittsburgh). I used 50 grains of 3F under patched Hornady swaged balls. I shot one group using .440 balls and what I think were .015" thick pre-cut patches pre-lubed with Wonder lube, and the same patches with the .445 balls, only I think these were .010" thick.
The front sight on this rifle is too high. Once I find my load, I'll file it down. In the meantime, since I wasn't on the paper at 100 yards, I shot these groups off the 50-yard bench (you can see from the results that the sights still shoot low -- even at 50 yards).
I still need to fool around with some different patching material, and have some pillow ticking I want to try. It's one big piece, so I'll cut these patches at the muzzle. Will likely lube it by just rubbing some Wonder lube into it.
Note that the group with the smaller balls was around 5-1/8" in diameter (I fired two fouling shots first), but the larger balls delivered a 2-1/8" group -- less than half the size of the first group.
After each shot, I wiped once with a glycol dampened patch, followed by a dry patch. I used the same flint for all 12 shots, and had one mis-fire.
The .445 balls were a tight fit with the patches I was using, and I suspect that the pillow ticking will be tighter still.
I have done a lot of shooting over the past 50 years or so, but not a lot of flintlock rifle -- so all tips will be gratefully received. I'm no longer a hunter -- typically just punch paper at 100 yards.
If any of you are into reloading for, and shooting, vintage [cartridge] military rifles, you may want to poke around my website.
