I called the Police station a few days ago and asked about the range. Seems there was a problem with a park user and some shooters (?). Hopefully the city will get everything straightened out and reopen the range soon.
The town of Pawnee has a public range and it is just inside your two hour drive window. When I was there last they were plinking some pop cans.
Call the city hall for hours and access.
I shot some Golden Tiger a couple of years ago. I was told that it was hotter then Wolf Classic, I could not tell. I have never had any issues with any coated ammo in my AK.
