FYI Atterbury has some longer ranges that are open to the public from time to time. And I think that down south around Borden there is a club with longer ranges as well.
450 is the max I can get on our farm and I've found it to be doable with my equipment, yet enough of a challenge that it isn't boring yet to where I want to move out much past that.
Thanks, I've only shot at Atterbury once, and the 100 yard was as long as they had available at the time. I think I've planted the bug in my boss, and he's mentioned a few trees we may be able to "trim" to get us some more range, he wants to see what he can do with his RPR in .308
