Groups measure precision, scores measure accuracy. Back when men were steel and ships were wood they used string measure to determine who was best. I don’t recall the precise numbers but some years back a fella shot a 20 shot string at 40 rods with a string measured score of about 6”. That’s the aggregate of distance from POA to POI (center) for 20 shots. With lead and Lord Black.
Some scores of 10 shots at 80 rods were sub 10” way back then.
Lastly, and I’m not picking on anyone in particular, cast bullets are a rather demanding lot. They are near perfect or flyers will frustrate routinely. Too, if one wants to learn the shooting discipline in a hurry, start with a flintlock...offhand. Thou shalt follow through or the crowd will surely laugh at you.
