If you are having trouble seeing the sights you might try an EyePal stick on disc on your shooting glasses. Your mid-barrel rear sight should be about pistol distance I'd guess. Also you might try safety glasses with just .5 adjustment to enhance the rear sight without blurring out the target...
Track of the Wolf’s online catalog lists a shorter 1/4x28 for TC rifles plus the longer one you have for general use. I also think your longer one should be fine.
Mine is browned steel framed .50. The drop in the stock is comfortable for me but the fine front sight is becoming a bit hard to see. (when I got reading glasses the eye doctor chuckled and and said I was just the right age).
This year I've started using 0.5 clear safety glasses to sharpen up my focus. I've also considered a wider front sight and a 6 o clock hold on my Pedersoli Tryon, the factory sight is pretty narrow.
I've started wearing 0.5 safety glasses to sharpen up my view of the sights, it's worked pretty well. Previously I had bifocal reading/safety glasses so I could more easily focus on the muzzle while loading.
8 - 1.25 mm for my Italian made Parker Hale musket
5/16 x 24 for my Zoli Zouave
thread sizes are all over the place, I have saved some old Dixie Gunworks catalogs for reference
The Gardener bullets flange was pressed around the base of a paper tube using a foot operated die, the tube was then filled with powder and tied off. I've read of some reproduction Gardener press being made. I wonder if a push thru die similar to what Lee makes would work?
