I would like to have my 20 gauge SXS barrels regulated so it would shoot slugs with reasonable accuracy, right now the points of impact are about 18" apart at 50 yards. Is there a Gunsmith that could regulate the barrels and add rifle sights for me?

Apparently no one knows of a gunsmith that would do that type of work. I guess the next step would be to do a conversion to a double rifle.

T.Loy,

Keith Kearcher can regulate chokerifled shotguns. Not sure how successful the effort would be on an normal shotgun using slugs. Nor can I guess what the effect would be on birdshot patterns and points of impact should you still want to use the gun for bird hunting.

Regards, Tim

Make your rear sight with 2 notches; left one for right barrel and vice-versa. Brownell's has rifle sights for shotguns.

Mr Kearcher informed me that Browning bbls are brazed together- not soldered- and cannot be regulated. So plan B....2 sights?? I'll check out those sights, Thanks.

Somebody sells 12 ga SxS that are regulated and have sights, for about $1000 - $1100. Can't recall the name offhand, but there was a thread on this BBS a couple of months ago. The poster bought one and really liked it.

T Loy:
I just posted about this on an earlier thread, I know you already have the 20-bore, but I'll simply paste the earlier post in here for interest. Hope it helps in some way.

"Virtually all SxS double shotguns will 'shoot apart' with solid slugs. The exception is the purpose-built smooth-bore slug-gun, the most common being the Sabbati and Ugartechea offerings, and the rather less common Brignoli (..and there may be others).

If you can't find a purpose-built double slugger, the solution is to acquire a robust SxS double in good nick, knock a couple of inches off the barrels, effectively removing the chokes, and re-regulate for your favourite slug load. This is done by lifting the ribs, adding packing around the mid-point of the barrels to 'bow' them slightly, which effectively increases the convergence at the muzzles, then relay the ribs, fit sights, and enjoy!

A Wm Griffiths boxlock I shortened from 30-inches to 26-inches regulated perfectly with RC slugs when the muzzles were brought together at the shorter length and the ribs relaid. Didn't have to alter the packing at all!

BTW, a properly regulated SxS double should not 'intersect' at some specified distance, rather it should put left-barrel shots on the left side, and right-barrel shots on the right side, of a useful composite group at all practical ranges. I would suggest that a composite 6-shot group, consisting of 3 rights and 3 lefts, should fit into perhaps 2 inches at 25yds and 4 inches at 50yds with open sights to qualify as good. Smaller groups are better of course, if you can achieve it.

Just a thought on the regulation....You may wish to try some of the low velocity slugs...As I under stand it; most SxS guns are set to have shot patterns converge at around 40 yards...it would make sense that a slug with a weight/velocity closer to a normal shot load may produce better regulation results.

OK. I had a 311 Stevens 12 Ga that had been "sawed off". I didn't do it so everybody take it easy. I did rescue the old gun. I bought two choke tube adapters from Brownells, and two rifled chokes. The professional gunsmiths told me it could'nt be done. My friend who builds flintlocks made a cutter out of a pipe fitting, it looked like a hole saw. He filed out a section of the rib turned the hole saw over the barrels to size them and soldered the connectors on. I screwed in the choke tubes and started shooting. I regulated the barrels with a big chunk of lead for a hammer and lots of homemade Lee slugs. I backed off of the load about 10%. Two days of work and I could shoot a 8in inch group right and left at 50 yds. Finally my buddy soldered a scrap piece of rib in between the couplings. I killed a buck deer, a turkey, some squirels, maybe a rabbbit I can't recall, crows, and shot them round clay birds too ! The rifled chokes shoot shot good enough to suit me and the skillet. I had read an article Ross Seyfried had written about the Parodox and had to have one. Cost about 100$ and a load of wood. My friends think I'm crazy. They say you,ve got "good" guns why don't you use them.

Over 20 years ago I invented a sight (US pat 4,597,211, now expired) that solves your problem by having a separate rear sight aligned for each barrel, alternated on firing by the inertia of a weight.

Maybe you could whip up a simplified version, perhaps using a folding Lyman sight with a second leaf Araldited at 90 degrees on the back. If you read the patent, you might get an idea.
