There is a lot of National Grassland north of town by Weston where you can get a lot of long range practice in. There is also Grasslands south of town by Wright. Other than that, there is mostly private land. The local gun range seems to only cater to the trap shooters. The trap range is top notch, but the rifle range was very poor last time I went. Targets and backstops all shot up, lots of weeds and garbage around. There are only 2 places to get decent reloading components, but they are way expensive. Most people go to Rapid, Casper, or Billings to do their shopping. I have lived in Casper for over 20 years and have been in Gillette for about 7. My wife is a Gillette lifer for the most part.
I know you in real life... and your Facebook posts aren't fooling anyone...
