Re: 1000 YD. Targets (6X6)
The targets we use at the Williamsport 1000 yard matches are the old 500 yard military targets with some changes.
Our targets, when on the frames, measure 68 1/2" left and right and 41" up and down.
We buy them through the "National Target" company in New Jersey.
I think you could buy at least 100 or more at a time if you wanted to.
I don't have the number in front of me but I'm sure they have a web site.
