I own a Brno ZKM-611 .22WMRF semi-auto rifle that I purchased at auction some years ago. It's an absolutly beautiful piece that was used by GUN TESTS MAGAZINE as a test gun, then sold at auction to me in Orlando, Fl. Unfortunatly it's accuracy leaves somthing to be desired, in my hands at least (2"-4" groups at 50 yards). Is it me or the rifle? I was hoping to do some varmiting with this deluxe little gun.
