I have shot 1000 yard matches at Camp Butner, I don't know where that is from you. I live in Michigan and make the stop on the way down to Florida for the two week OBR matches the end of Febuary. They have the XTC matches there also (200, 300, and 600 yards)
Here is a link to this years schedule, the new one is out, but I don't see it on the website.
