I train w/ a lot of field bred English cockers and Iâ??ve gunned several cocker trials. If I were primarily a grouse & woodcock hunter, I think theyâ??d be almost perfect. They defiantly â??punch above their weightâ?�. Iâ??ll use the analogy that they are like using a 20 gauge for pheasants. It can surely be done under the right circumstances but there are probably better choices in heavy cover.
