I have a single shot, shotgun 20 guage the gun says chambered 3inch modified. What does this mean. Do not want to load the wrong ammo. Thanks in advance all... :confused:
 
3 inch 20 gauge, means that 3 inch shells are the maximum size of shells that it is chambered for. The shotguns that say: 2 3/4 mean that 2 3/4 is the maximum shell for that gun. You can use a 2 3/4 shell in a 3 inch chamber.


stuff like "modified" and "full" indicates the choke.
 
I have other shot guns that are marked 23/4 and 3 inch The way I was taught you match your ammo with the gun no questions.

Its a good habit and prudent to validate nevertheless in the event of slightest doubt. In general, simply bear in mind the following....

- 3.5in chamber = applicable cartridge lengths 2.5in, 2.75in, 3in and 3.5in only. Note: The 3.5in chamber will apply to 12ga and 10ga shotguns only.

- 3in chamber = applicable cartridge lengths 2.5in, 2.75in and 3in only

- 2.75in chamber = applicable cartridge lengths 2.5in and 2.75in only

Shotgun action type will also greatly dictate the use of the appropriate cartridge length. Example - the smaller 2.5in cartridge will not effectively cycle in semi-auto and/or pump actions etc since those firearms will have a minimum chamber length of 2.75in.

There are a few other variables when it comes to shotguns with short(er) chamber lengths such as 2.5in etc. However, the above should serve most info needs in general.

May not be out of place to mention that you may also wish to further validate choke type and what to shoot out of which choke i.e. steel shot, slug etc. :)

Thanks to all who helped me clarify my question. Proper information is always welcome and this is one of the reasons I am part of this Site. That said if you do not posses the knowledge to answer the Question and prefer sarcasm it is not welcome. Thank you all again, I am off to try the gun... :ar15:
 
I'm always amazed by some of the replies here on CGN... Some guys are helpful, & some are downright unhelpful! Not everybody knows guns inside out, I know it's repetitive but being polite & helpful when someone asks a question, would be nice!

Cheers
Jay
P.S. Suvivor, have fun!
