If you mean the one in the picture, it is a NRA 25 yard pistol target. In black
powder matches it is shot at 25 yards in all styles of pistols both slow fire and
timed fire. Revolver also. Same target is used at 50 yards except the "8" ring
is black also to give you a larger aiming point. The "10" ring is just slightly over
3 inches in dia. Most all matches are 10 shots. Hope this answers your question.
If not, ask again. I can be dim-witted at times.
