Mr. Twicebarrel I have to disagree. The 28 gauge gun is a wonderful choice for shooting bobs over pointing dogs, even in the Great Plains (like around Amarillo). And the 28 gauge gun is still in its element when taking decoyed mourning dove or ambushing them over an evening watering hole.
But the 16 gauge is certainly more versatile.
Lloyd thanks for the pictures. Nice contrast. A couple of seasons ago a local civic club put on a bobwhite hunt on one of its member's land. I ran my dogs for them to hunt behind. A young man was carrying a Dickenson 28 gauge. He shot it very well and put the old men, including his dad, to shame.
