Brian:
I owned a Cooper in .204 Ruger for a number of years. Took it prairie dog hunting once and fired 1000 rounds through it in three days with no failures or stumbles. It was a fine rifle and I liked it a lot.
I sold the rifle when I decided that was my last prairie dog hunt. I have a couple of other small centerfire rifles available on the off chance I get the urge to kill another woodchuck (unlikely), but the proceeds from the Cooper went toward a 28 gauge SIACE hammer gun that I wanted (and use) a lot more.
I thought they were fair value for the price, particularly if you are a blue steel and walnut fan, which I am.
