| Is the shell size a shotgun is able to accept (2 3/4", 3", 3 1/2") dependent upon the receiver or the barrel? Thanks. |

Nearly all new shotguns you buy today will have receivers that will handle up to 3'. The chamber length of the barrel is the most important factor. You can probably get away with shooting a 3' shell in a 2 3/4' shotgun receiver with a 3' chamber barrel, but extracting it and ejecting it will be an issue. |
| Both. The barrel's chamber has to be long enough to accept the shell and the receiver has to be large enough to allow ejection. Check out the difference in the ejection port of an 2 3/4 gun vs a 3 1/2 gun and note the size difference. I believe there's also an issue with the shorter receiver being able to allow the bolt to come far enough back to allow a shell to feed properly if you were to put a 3 1/2 inch shell in a 2 3/4 inch gun. |

Technically the barrels chamber length is cut to the length of a fired shell; so a 3' chamber is actually 3.5 inches long. A 3.5' chamber would be 4'. Shooting a 3' shell in a 2 3/4 chamber results in over pressure do to the lack of space for the shell crimp to expand. |

Are the ejection ports on 870 receivers all the same size to where the barrel is the factor in the different size shells different 870 models can fire? Thanks for the replies.  870 recievers can vary based on model and vintage...some in port length and some in the placement of the ejector. Here is a guide to knowing what you have straight from Remington |
