Green Pea, the black on the original was 1 3/16" diameter, which is what I used.

It looks like the next "match" will be 20 yds off-hand w/ target off of here, under resources, the 25 yard one. It prints out a little smaller too, but doesn't matter, as you can put something over it to see better if not using scope. We had talked about 30 yds. but one of the guys would have to go pay at a range to get 30 yds. so we made it 20. Looks like we're in for a battle w/ the dead eye from Ohio! LOL
