I got my first ground squirrel of the season a few days ago....
not with a 223 or 22.250..... actually got it with the right front tire on my 4 Runner....
the tire made it go "Splatt" just as well as the 223 or 22.250.
got one I'm tracking right now, in the yard digging new holes on the creek bank...
its just a matter of time, before he meets Mr. 17 HMR.....
Update at 3 PM Oregon Time.... Sammy Sage Rat met Mr 17 HMR.....
Sammy Sage Rat is no longer with us....
Mr. 17 HMR did what Mr 17 HMR was designed to do....
