I've seen all sorts of mixed messages about using more than five shorter shells in a semi-auto shotgun chambered for longer rounds, so I asked the RCMP.
Here's my question, and their answer (TL
R - It's no more than 5. Ever.):
And answer (key bit bolded):
I was surprised at this response, given how common the practice of using shorter shells to increase capacity is...
Just thought I'd share.
Here's my question, and their answer (TL
1. For shooting clays/targets (not hunting), what is the maximum number of cartridges I can legally load into the tube magazine of a 12ga semi-automatic shotgun chambered for 3.5” rounds (ie this one <https://www.beretta.com/en-us/a400-xtreme-plus-synthetic/> )? I believe the answer is that the tube magazine cannot hold more than five 3.5” cartridges. So five plus one in the chamber is the max legal loadout.
This appears to confirm it:
My understanding is that a legal magazine for that shotgun would be one where it will not accept a sixth 3.5” cartridge (the cartridge it was designed for), making the number of shorter shells can fit irrelevant, and I could legally fill it with any amount that fits.
This appears to confirm it:
3. (1) Any cartridge magazine
2. What I can’t find an answer to is how many 2.75” shells I can load. Because of their shorter length, I could load a sixth shell in the tube….but would that make it illegal? “Five rounds max” is a pretty prominent quote in the research I’ve uncovered.(a) that is capable of containing more than five cartridges of the type for which the magazine was originally designed and that is designed or manufactured for use in
(ii) a semi-automatic firearm other than a semi-automatic handgun,

And answer (key bit bolded):
Thank you for your correspondence.
With one popular exception; all centerfire, semi-automatic long guns have a magazine restriction of five shots even if you are using a shorter shell. Five shots plus one in the chamber exceeds the five shots restriction. This includes both shotguns and rifles. The exception to this rule is the M1 Garand, which has an eight shot magazine. This exception is due to the internal, top-fed magazine in the M1. It would not be feasible to require this magazine be pinned, so an exception was created. Firearms that have a magazine capacity greater than five rounds must have their magazine pinned or altered to only allow five rounds (again with one exception, the M1 Garand).
This five shot restriction does not include pump, lever or bolt action firearms. It also does not include rimfire ammunition.
Rimfire ammunition, for the most part, is more commonly known as 22 LR, 22 MAG and 17 HMR. There is no restriction on the number of shots a firearm can have in these three caliber's.
