One of my HS classmates is downsizing and I got a screaming deal on his dad's Superposed. It was well used, well-maintained by a gun guy. It's been carried, rubbed, the checkering is mooshed, but it's tight. I really liked his Dad so this is kind of a keepsake.
But I want to bring it up to "modern" meaning extended screw-in chokes and backboring. Any howls of outrage from the Browning fans here, or is this a good thing that John Browning would approve?

PLEASE don't ... if you want a utility over/under just get a Citori...

I have probably 20+ and would never consider choke tubes - but to each his own.

I would never have choke tubes installed in my Superposed. I would not change one thing on it.

I would not mess with it. I am sure it shoots fine the way it is.

Leave it alone!

Also, few know that the chokes of the superposed aren't like conventional choke, where they begin to choke down near the muzzle. The Superposed barrels taper almost the whole way. That's one reason the guns shoot such good patterns in general.

I have my late dad's 20 ga 26" IC/Mod with solid matted rib right here, and it's worn about like your gun. It has wonderful character, and I wouldn't remove even one small scratch.

My grandson shot his first quail on the wing with it eight years ago.

If you are a handloader you can manipulate patterns to some extent with different loads. As others have said I would leave it alone.

From a purely technical perspective, many Superposed guns are too thin at the barrel to allow for choke tubes.

While I have a number of shotguns with tubes, and as I shoot much more now than I ever did before retirement, I’m far less enamored of the tubes. With the great shells of today, choke matters far less than it ever has.

Another vote for leaving it alone.

I'm with the don't do it crowd. As said above Superposed barrels can be thin. A friend of mine had a gunsmith "install" choke tubes on a 12 gauge and it was ruined. There are plenty of different loads out there to help a tightly choked gun. Also plenty of new shotguns with choke tubes.

never fails....guys get handed vintage model a's, and want to put mag wheels on it. :>

Very true and something the old timers seem to know more about than today's gun writers. Major Charles Askins Sr. was a scattergun guru nearly a century ago. I tried some of his techniques, such as getting wider patterns with high powered #9's for quail, tighter patterns with slightly heavier shot at slower speeds. Seems the medium chokes are the most adaptive to that treatment. The Major had this gun choked by Browning to his specs. He was a great desert quail shooter, and according to his son, Col. Askins, didn't miss many.

I ended up with his personal Superposed. Here is a link to that project, lots of otherwise unpublished info on the Askins clan and shotgunning in general.

Wow, it's unanimous!

Okay, I guess I'll do an initial fit to me (pull is 15 inches) and see how it patterns/shoots. Thanks, everyone!

I am not against it. But I do question if it is really needed? Or did you just want the novelty of choke tubs?

I have other shotguns with screw chokes and there IS a difference/benefit. I've also got rifles with adjustable butt/cheek and that's nice to have, too.
The Superposed is like having a 55 Chev. There's "stock" and then there's "modernized."

None that is going to make enough difference to be worth the money! A Superposed is far from a any classic car to me. Not a bad gun but not in the realm of classics to me. Again I am not against back boring, lengthening forcing cones, or adding thin wall chokes. But the question still remains WHY?

Just because? I mean, most of us don't "need" firearms anyway, right?

Sell it and buy a Benelli auto.
