I have already heard 2 different opinions on the subject. First gunsmith said no, the second said that they can use thin wall with choke constriction limited to an external extended choke tube...

Do we have any expert opinions out there as I would really like to be able to shoot steel shot out of my superposed at reasonable ranges (so I am looking to get chokes in the skeet II to Imp-Mod range). I love shooting this gun but the F/M set-up is too tight for my shooting.

Thanks.
 
If you can measure the wall thickness of the barrels, it can be determined as to if you can have tubes installed. Briley thinwalls are probably the ones you would need to go with. If the gunsmith measured your wall thickness, and said no, I guess your hooped.
 
It's really quite simple.Thinwall chokes require a minimum barrel steel thickness.Either you have that thickness or you don't.If you do,great!If you don't,you're out of luck.

A buddy of mine had his 3200 done in Eastern Canada and no gun has a thinner barrel than the 3200.He's pretty happy with the job but it wasn;t cheap.I believe that it's threaded to accept Briley choke tubes(not 100% certaib though)He's moved to Alberta now but if I can get ahold of him I'll find out who he got to do it.He lurks around here sometimes under the name Hilgy.You might want to search for him that way.

Not all gunsmiths know what the hell they are taliking about!!! Believe me. And what constitutes a gunsmith???

Check with briley and yes thaere are many gunsmiths on Canada that can install them for you. For this procedure, find a gunsith experienced with installing thin walled tubes. Call around

visit
www.firearmscanada.com it has a pretty decent (somewhat outdated) directory.
 
Everything I've read says not to shoot steel with a Superposed. There could be other issues other than just the choke, such as the forcing cone angle and length that may not be steel friendly. My Mossberg is for shooting steel.

They are the Briley rep for Canada & I was told that they have the set up to do the thinwalls.

They have the set up. Whether they will do it and how long it will take and what kind of BS you get back from Lawry during the entire process is another matter entirely. Been there, done that.

The Browning Superposed has very little gap between the barrels at the muzzle end. Sometimes they can have choke tubes installed and sometimes they can't. Briley will probably want to see the barrels before they decide.

Teague in the U.K. can install choke tubes in just about any gun including the Superposed. I don't know what the procedure is to get them installed but if you Google "Teague Canada" it will take you to the Canadian dealer for their products. It may mean shipping the gun to the U.K. unless they have someone in Canada to do the work. Expect a long wait.

The final problem however is your desire to shoot steel. Not all Briley thin walls are suitable for steel shot unless they specifically say "For Steel" on them. The combination of thin barrels, thin chokes and tight tolerances at the muzzle probably precludes the use of steel in this gun. Whatever you do specify that you want to shoot steel through these chokes. That may further reduce your already limited options.

Buy a new shotgun rather than ruin the Superposed. Or shoot a different non toxic shot. You could get a used Citori for cheap and not have to worry about shooting steel out of it.
 
Too much choke

If it is just a matter of too much choke as you say what about taking it to a competent gun shmit and getting Mr. adjustable reamer in there and remove some constriction and re-polish ? I have done a couple that way for myself worked out well.
I would not do it for other people but a good smithy would, and probably do a great job that can look as good as original. Very cost effective I would expect also.

Good Luck and good shooting !
 
The Superposed has extremely thin barrels and where the barrels meet at the muzzle, they have been thinned even more. As far as I am concerned choke tubes are out. I did see one with one tube done and the threads could be seen on the outside of the barrel.

You could probably shoot steel through them if you opened them up to what ever the bore measures less about 5 thou... just a little constriction. Steel shot requires very little constriction to get a good pattern. Most people shoot steel through too tight a choke and the pattern is distorted.

Anything you do to the Superposed is a risk you take for sure.
 
I was wondering why no one asked why he needed choke tubes in a superposed in the first place? Leave it alone it's a classic. Just shoot it to it's limits.

I mainly bird shoot, and have 4 o/u, but I love the feel and fit of the superposed. I picked it up cheap ($500.00 ) and in excellent condition. I usually shoot between 2 and 3 cases of shells at ducks and geese per year, so it would be used heavily. My 101 has over 100,000 rounds through it and is kind of loose, and I want to switch to the superposed. Currently, most of my shooting is over decoys and I usually shoot a skeet 1 or improved cylinder in the bottom , and a skeet 2 or modified in the top. Most of my shooting is under 35 yds so I really need an open choke. The use of bismuth or other non-toxics other than steel would be prohibitively expensive when we are talking 500-700 rounds per season. I currently use only 2.75" shells, with #2-#4 steel, usually ligher loads 7/8- 1 1/16 oz at high velocity. I have shot a couple of boxes of steel out of the superposed, but you either ink-blot the birds or miss completely. The gun is currently a mod/full setup.

As an alternative, I guess I can live with reaming out the bores to a more open setup, such as mod/imp cyl or mod/sk 1 .

Any suggestions out there for this one (preferably from hunters who field shoot ...again I try to get the birds in tight and shoot em close, about 90% of shooting under 35 yds)?

Thanks for the response.

ps. If I do look at reaming the bores, can you tell me who is very competant, as I would like to ensure both barrels maintain the same impact point , which is now flat with the bead. I live in Manitoba, so the prarie provinces would be more convenient for location.

Thanks again.

I think you are fortunate to not have split the chokes wide open on your superposed. I have seen a modified choke split with steel shot. I have seen others bulge.

Using steel shot O/U's work very well with skeet one and skeet two chokes... excellent patterns. Tighter chokes simply distort the pattern of steel shot with no benefit in distance, actually a loss. If the alteration is done with any care at all, point of impact should not change.
 
Paul I would think that if you start shooting the 1550 fps loads in the SP it won't be long before it loosens up as well, I have one that I loaned to my brother that is used only for upland hunting. Its still nice and tight, howevr you start pounding high velocity loads through it and in no time it will be loose like your 101. Those guns weren't made at a time when high velocity ammo was the norm. well if you insist on shooting waterfowl with the gun you could go with a Tungsten Matrix #5 in the full barrel and a load of #4 in steel in the mod barrel. Good luck.FS
 
I've e-mailed another friend who did this with his citori, and he originally went mod/ic , but finds it too tight. I'm pretty well convinced that I can go to a light modified(sk2) over a skeet 1 . This should give me the first shot patterning about 20-25 yds, and the over barrel should pattern in the 30-35 yd range, which is my normal shooting. (assuming 70% is about ideal pattern).

I think this would hold more to the aesthetics of the original gun rather than screw chokes as well. I do shoot faststeel in the guns, but rather light loads. I re-load ultrafast 1700fps+ loads at only 3/4 oz. and am able to use smaller shot (#4 or #5) with devestating effects on the ducks .

I would still like your input as to a recommended gunsmith to do the reaming and polishing. Who do you suggest?

Thanks again for everyone's input. It is appreciated.

Hi Paul, I too have a Browning Superposed that was choked too tight. I had my gunsmith open it up to Imp.Mod & Mod. Patterns great now. You'd be best to only use a Hybred Shot, i.e.: Bismuth or Hevi Shot just to be safe. The owners manual from Brownings website is very specific on shot pressures that your reciever and barrels can handle. Or you could send a email to Shotgun Sports Magazine and the editor could offer more reseached advice.
Good Luck,
P.S. Mine is a Siver Pigeon Trap model 30 " barrel with Gracoil Recoil Reducer and it is for sale.
 
keep it simple. I am not an expert when it comes to shotguns, but when you are talking about shooting steel shot in older shotguns (not including damascus steel barrels) I think what you need to do is get someone to ream out any full choke barrel to "modified" and you should be O.K. with steel shot. If you are just out shootin greenheads and geese this should work.
