Where can one source this in Canada?? Somewhere around the GTA would be ideal!
Would be for an old Belgian sxs that doesn't have a full 2 3/4" chamber. Yes it's been nitro proofed for smokeless powder.
Would it be safe to shoot 2 3/4" in it (I'm not sure) or will it even chamber & close on a 2 3/4" shell?
I'm specifically looking for slugs, buckshot and #7, #8 or #9 trap loads.
 
Hmmmmmmm ......... wait a second! The description for that ammo says

Sellier and Bellot has been producing cartridge ammunition since 1825. Today Sellier and Bellot produce ammunition using high quality components which is the choice of hunters, competitive shooters, law enforcement agencies and militaries around the world. This ammunition is new production, non-corrosive, perfect for sporting purposes whether the game is on four legs or a target stand. Designed for use in all 2 3/4 and 3" chambers (2 5/8" based on equivalent European sizing)

So a Belgian European gun marked 2 5/8th will take North American 2 3/4" shell no problem? The box in the photo and the description on the website both refer to this as 2 3/4"

If that's the case then I could probably just shoot 2 3/4" birdshot loads?
 
Could be marked different. Our modern 2 3/4" chambers is 2 3/4" with the crimping expanded into the chamber.

Maybe the old ones didn't include the crimping into the chamber in the designation?

Edit, you should be able to measure it actually...

A regular star-crimp in a 12ga shell is about 1/2" long so a 2-3/4" shell without the crimp is actually 2-1/4" or so (different, brand-to-brand). The S&B shells I've seen are actually slightly shorter in the body so really are 2-5/8" with the crimp open. Older ammo was all roll-crimped and has less than 1/2" of the length rolled in.

Even US made roll-crimped ammo is sometimes shorter. Federal roll-crimped slugs for example are only 2-5/8" when fired. I believe Remington sabot slugs (but not foster slug) are also 2-5/8" when fired instead of 2-3/4".

I've talked to many people who regularly shoot target load 2-3/4" US shells in older 2-5/8" European shotguns without any problems. The chambers often really are 1/8" shorter but so long as the forcing cone is long enough, maybe it doesn't matter in terms of pressure? I don't know.

Ah Ha!!! That's the type of info I was looking for! Much appreciated. I have a gun in transit to me as we speak and the chambers are marked as 65mm ........ not 70mm typically associated with 2 3/4" but the seller says it busts clays no problem with modern target loads .............. I started to second guess the whole thing. Hopefully it's a nonissue and life is good. I think it's a good/better quality gun in what apperars to be excellent condition and not a low end early 1900's gun. I believe the date code is for 1926. Here's a shot of the barrel markings
