200-yard "roundball" gun

I drug old Santa Fe out for some 200 yard work today. My back sight is a little loose and until I tighten that up or replace it, I'm not worrying much about zero... so the object was to just get it on paper at 200 yards so we could see how she'd shoot Hornady .54 ball at that distance. The set-up looked like this:



As soon as the first shot landed in the bottom-right corner, I started shooting for groups. I shot with two different patches; one tight and one almost loose. Caps were CCI No. 11 Magnums; charge was 75 grains of Triple Seven, thrown from a flask.

Set trigger was used for all shots except the one at low-left, marked "Flyer-Early!" Duh. That was supposed to be the first shot of the second group, but I 'set' the front trigger before I had the sight picture perfected. "Surprise, Gomer! Big rifle go BOOM right now, when you pull FRONT trigger." When I got done laughing at myself, I ignored that shot and fired three more.



The WAY tight patch resulted in the ball being deformed (flat spot) from driving it into the muzzle. That group is the holes marked '1' and it spans 7 3/4 inches.

Oddly, the loose patch shot to the same POI and considerable better at 6 1/2 inches, discounting the flyer.

All seven shots went into just over 9 inches- not too bad for a old round-ball gun with primitive sights.

Believe I have a shooter here.
