For what it's worth, my 28ga is a .54 GM smoothbore barrel fitted to a flint-lock Lyman GPR that I use mostly for deer and hogs on Corps of Engineers land since they allow shotguns only, so it's kind of my way of skirting the regulations that forbid use of a rifle. It shoots PRB very well to about 60yds, and sometimes 80yds if I cross my eyes just right. But you can see that this is just a rifle without the rifling in it, and not what most would consider a shotgun, as a 15/16" 32" barreled 8.5-9# gun isn't the best thing to swing on a dove. And I do have both the front and rear sights on mine, which are a blessing when shooting PRB, and also a help when I attempt to chase turkeys with this gun (haven't connected yet, but maybe this spring), but didn't bother me the very few times I took this gun after dove. In the end, this gun aims very well, but swings like a heavy rifle, and not like a proper shotgun. I hope that helps you out some, and I'm curious as to what you end up with, as I'm always tinkering with mine trying for both better patterns and better accuracy.
