I am looking at getting a fully rifled barrel for my 870.  Remington's description of the barrel lists it as accepting 2 3/4 and 3 inch shells.  Other places describe the barrel as accepting 3 inch.  My question is that as long as the barrel is marked 3 inch, can you also shoot 2 3/4 inch shells.
Thank you

Re: Question on 2 3/4 and 3 inch shells
A shotgun's chamber length identifies the maximum shell length that can be safely fired in it.  Anything shorter is fine, since standard shotshells are essentially straight-walled, and headspace on their rims.
This video explains shell & chamber length in detail.

No 
The barrel and receiver must be marked 3".
