What are the allowable distances to shoot at this range? I would hope more than 100 yards, but looking forward to camping in the area and also utilizing the range.

It goes just past 400 yards. There's a roughly 8-foot tall by 10-foot wide metal frame at 400 yards to hang steel targets on. There's a berm at about 200 yards, and another at 350-ish.

I think the max is 325ish.

150 to 200 hundred yards, it's a really nice range and the people that do go there are pretty nice

At least 250 it a big valley that you can shoot in. The vslly works it way up hill can set targets pretty far. Tables slso available. Great place to camp around
