I used to own a Heym express rifle in .600 NE. It was an excellent rifle. Offhand, I could shoot a 3 inch group at 50 yards because it was well balanced and had a nicely fitting stock. The sights were excellent. The action was smooth and the rifle was well-finished. It was not a best quality rifle, but it was not that expensive either. Eventually I sold the rifle because it was too heavy and kicked too much. At heart I am a recoil wimp.
