I shoot a 20 gauge,and I find that by shooting only 7/8 ounce loads on trap (clay birds) that it helps me in the field. In the field I go to 1 ounce loads and the extra shot gives an better than 80 percent kill ratio, on Pheasant, chukar and quail. My theory is by using a smaller pattern in practice, when I go to the bigger hunting pattern i' m just that much more deadly. Bob[8D]
