Generally in each shooting sport, accuracy of half the ten ring is often quoted as a standard. In Bullseye Pistol, the ten ring is the same size at 25 yards and 50 yards. Only the 50 yard line if fired slow fire, at 25 yards you have either 10 seconds to fire five shots (rapid fire) or twenty seconds (timed fire). You shoot each timed fire or rapid fire twice to get ten rounds on the target. This is not as easy as it sounds, as you are shooting with one hand, offhand. Those who shoot using a rest on top of some 300 lb concrete bench ought to see just how tight a group they can fire offhand, one handed, at these distances.
Now this was an exceptional group by a good pistol shooter:
Ernst, in testing ammunition, decided this was good enough for the 50 yard line:
and this was a bragging target shot in competition
this is his 25 yard slow fire target. Sometimes we cannot use the 50 yard butts, so we shoot on a reduced target. But it is a lot harder to shoot the same score, the rings were adjusted so that scores were comparable.
When I can do this, two handed, at 25 yards, I am happy
I think this was fired at 25 yards, back then everyone shot Bullseye style, that is one handed. Rapid fire times would have been the same. I have no idea what course of fire they were shooting that required 60 rounds rapid fire. This was made in 1947 and it may have been shot with a revolver. Notice the ten ring has gotten smaller.
