Shooting range

[1000YardStare]

Hi everyone, new guy here. Wondering if anyone knows of a rifle range in Oklahoma or close by, public or private, that a guy could visit and be able to shoot a mile? So far my longest hit is a thousand yards, and I've been itching to try my hand at making a hit at a mile. I have a fairly large ranch that I work on that definitely has a few clear lines of sight for a mile or better, but it's all canyons, and I have yet to find a range finder thats not terribly outrageously priced that can consistently measure ranges that far. Thanks in advance.
