Some of these topics are a bit humorous to see being rehashed again and again. Like what is the ultimate shot size? This and the Model 21 topic only come down to personal preference. No more.For anyone that doesn't believe that 28 gauge is a viable option on most game birds, tells me more about their own abilities, or lack of experience with the gauge. If not for the cost of shells, the 28 would be far more used than it is currently. The 28 has killed numerous wild pheasant, chukar, turkeys, ducks and many coyotes for me, it will do the same for any of you. IF you shoot straight.
