I use these guns for Grouse hunting which is a passion .The Merkel I use in the early season and thick cover as it has improved cylinder barrels and the Sauer for later season and open country as both barrels are full choked .Interestingly enough the Merkel will put a Brenneke slug from both barrels into a playing card at about 40 -50 yards . I have tried this with a few open choked SXS shotguns I have owned and have never came close to doing this . This gun must have been regulated for slugs at the factory .Never shot slugs from the Sauer but it patterns magnificently well .I even took the Merkel one time to a local Running Boar target shoot .Everybody laughed until I won. A Brenneke Rottweil slug at 50 yard kills a Deer quite dead I can tell you although I mostly have used this Gun for Grouse and Pheasants and left the Deer for the rifles.
