As the title says .........
I have a 16,000 ish serial number W C Scott and Son, 12 gauge, SXS, in measuring the chambers it appears to be a 2 and 3/4 inch gun. My question is ........was it common to have a side lock hammer gun chambered for 2 3/4 ? I was under the impression that it would have been 2 1/2 inch chambers. there are no proof stamps indicating size.
It does not appear that the chambers have been lengthened but it is hard to verify.
any thoughts would be appreciated.

If it says between the barrels "imported by Abercrombie and Fitch" it was probably made for the American market and the chamber have been 2 3/4" all along...Geo

16,000 serial numbers fall in 1872 according to the W&C Scott history.

Prior to the Proof House revisions of 1925, 2 1/2" chambers were (usually) marked 1 1/8 oz. and 2 3/4" chambers marked 1 1/4 oz.
Any almost 100 year old gun deserves a good check and clean, with a bore scope examination and wall thickness measurements. If the end of chamber wall thickness is > than about .100", if the chambers were lengthened, though out of proof, it doesn't matter if using loads for which the gun was designed.
OK - just saw the DOM post. There was no load indication prior to the 1896 revisions.

2 3-4” almost never. If the gun has been in the us long? If so most likely answer is somebody eased the chambers from 2.5 to 2.75. Measure the wall thickness. If greater than .100 you should be ok with same pressure loads. If under .080 I would not shoot it. Between you must decide.
2. 1/2” was standard for the period. Even longer shells often just were loaded with more, better wadding. Nothing was loaded to what our factory 2 3/4” factory hunting loads are today. That’s a complete non starter. Plus at 130+ years caution is your first responsibility to the gun, yourself and others.

Thx KY when you say almost never, I am assuming then that it was indeed possible (although unlikely) that it could be original chambering.

can anyone tell me in what circumstances it would be possible that the gun was chambered in 2 3/4...?
FYI the gun lives in Canada and has been here for a very long time in the same family.

If your gun dates to 1872 I'd say your chambers are not original length. The British standard stayed 2.5" but a gun built for export to the USA after USA standard became 2 3/4" would have been built to that chamber length if specified by the dealer. In that time period I would think a hand built gun could be ordered with any chamber length a buyer wanted, but 2 3/4" just was not standardized even in America or Canada in 1872...Geo
