then i would get BC
Just because with the hevi metal if you buy #2 shot 60% of the load will be steel #2's and the other 40% will be hevi shot and will consist of # 2, 3, and 4 shot which means you will have a longer shot string then with other loads where the load is all one size, but i have found that the hevi metal threw a PM is deadly on birds out to 60 yards, but guy i hunt with uses the BC threw a briley M and he can kill them clean out to 60 yards also.
