Turns out I can get a much wider variety of patterns simply by switching loads than I can from switching barrels.
Well, yes, that's what I woulda said if you hadn't already figgered it out by yourself.
So---Some Thoughts:
You could sell your Modified barrel (Armslist, Gunbroker, NFOAForum, whatever) and not have to mess with cutting it off and then either re-choking it or adding a PolyChoke. And then buy yourself some kind of a used Rem870, Mossberg 500, or general equivalent thereof for a housegun. Plenty of 'em out there.
Or you could sell the Full barrel, keep the Modified to shoot trap, skeet, and/or field.
Or if you wanted, you could mount the Modified choke barrel on the Wingmaster and try shooting skeet with it. If you want, I'll introduce you to skeet shooting at Harry Koch Range in Omaha. I'm not very good at it, but know the skeet process and could help you get started. And then if you didn't like skeet, you could still sell the extra barrel. Just a bit more used.
Sometimes these modifications cost way more than expected and then often don't turn out the way you imagined they would. Never happened to me, please understand. It's just that I've heard of it from Other Guys.
FWIW,
