Ken,
Are you using 7.5's and 8's on wild pheasants or pen raised? Over pointing dogs or walk-up with flushing dogs? I realize that many probably think the question unnecessary, but I am of the "shoot high brass #5's at wild birds and low brass 7.5's at pen raised only" crowd!! I have learned a good bit in the mere 13 years I have been hunting pheasants, but I am still not able to get away from that feeling as stated above! Hey! I have at least graduated DOWN to a 20 gauge for pheasants from the 12's that I so dearly cherished and swore by for many years! Of course, I have old shoulders with motorcycle wreck scars that prompted me to first explore the joys of the 20 gauge.
