The closest range that I know of that go to 1,000 yards is in Rexburg, Idaho. I don't know the times that the range is open. We try to have some days that are open for practice at our range. Usually these days are combined with working parties so we can get some volunteers to help prep the range for a match. I will send out a notification for such working/shooting days so that you can plan on attending. You can probably plan on the 28th of April.
