I didn't get to shoot last months match due to weather and an archery javelina hunt.
Got to go out yesterday, it was a really nice day lots of sun and temps ranged from low 50s to high 50s. Light wind coming from the North East between 5 and 8 MPH.
I was using my .40 Getz barreled squirrel flintlock rifle. Firing a .395 ball with Jo Ann's #40 drill. lubed with bear lube. All this sitting on 50grains of Dupont3f dated 1963.
I shot all the targets offhand. From left to right, the first target was my best, which I score a 48X, the second I score a 47 X , the third I score a 46x.
I laid the targets over another and lined up the rings and used a caliper to determine half ball. At any rate it is a moot point.
I shot the targets vertically. I compared them with this same target that I shot in August with the same gun at a different range. I have determined I should make a shader for my front sight, for target shooting. The POI as far as windage goes is highly affected by the direction of the light.
