For the same reason they used them in the past, they are so versatile. The same gun can be used with roundball, buckshot, or fine shot. I'll probably use shot the most but a ball will always be an option. Besides all that, I always wanted one of them thangs.
I like those soldered on front sights. The brass barrel lug I have can be filed to be decorative.
Thanks for the posts.
I should have noted, for that front sight, I had to file a lot of rear sight off to bring my point of impact down to point of aim. Even at 80 grains 3f and a .595 ball it was shooting high, several inches. Every load tried from 65 grains to 85 grains and .595 balls to .610 balls, patched or in a wad sandwich,,,, all shot several inches high at 50 yards. When I got the groups I wanted, then I filed the front sight until she hit where I was aiming.
Progression,
Good group for shots 3,4,5, and 6 (9 and 10 ring) but look how low I had to hold.
Different loads but also working, slowly on rear sight height. Better than before....
Still hitting too high.
The two shots in the black are now point of aim/point of impact for the sight in the photos previous. That's offhand, can't find my bench shot groups from final sight-in.
As you can probably tell, I don't shoot offhand at 50 much,
, mostly kneeling or sitting on the ground.
