Closest place would be Eastern Nebraska Gun Club if you could find a member to bring you with. Otherwise Hamburg Bend WMA near Nebraska City is a place you can target shoot, just make sure to find a good backstop and clean up your trash (or any other trash you see). I work at the Cabela's and when a guy brought one over to buy we checked out the bore and it had the best rifling I have seen on a Nagant. The price has gone up a decent amount, but buying online and paying a transfer fee would even it out a bit.
