Thanks all. That's the kind of input I'm looking for.
BTW, Skeet38, Welcome to TFL. You'll probably get to liking it even better as a poster rather than just a lurker. Lots of good folks and knowledge to be gained here.
Mention of the old Winchesters reminded me that my Dad may still have a one of some kind tucked away in a closet. As I recall, he won it in a raffle or something back around 1970. Fixed modified choke? 3 shots only with 2 3/4" shells only? Or never removed the plug? Jogged old memory tells me that I may have borrowed it once for an impromptu pheasant hunt. Dad is several hundred miles away, but it sounds like I might need to make a phone call ... Thanks!
