remington 1100

I had bought my dad this gun for dove a year or so ago and we used it for dove worked perfectly. but today we went duck hunting and the barrel says 2 3/4 on it but my dad was shootin 3 inchers fine today cause he left the gun in the case scince dove season but should we not ahoot 3 inchers or is it a pleasant suprise ?

Eventually you won't get away with it...

If it is a 2.75 barrel it should not eject 3" shells. Don't have a clue.

If it says 2.75", ONLY shoot 2.75".

Chamber length has little to do with a guns ability to eject a spent hull. Ejection port size controls that.

Years ago Remington sold a 2 3/4" and 3" chambered barrel for standard receivers. They only had one gas port drilled in the barrel. The issue and one reason they probably don't sell it anymore is because not all spent 3" hulls would clear the ejection port. The other issue was because of only having one gas port it would no longer cycle low brass target/dove loads.

You shouldn't shoot 3" shells out if a 2 3/4" chambered gun for two reasons. The chamber isn't long enough and will cause excessive pressure with 3" shells. Also the standard barrel has two gas ports allowing too much gas to cycle the action with magnum 3" loads. You risk premature wear and broken parts.

I wouldn't , getting away with it a few times doesn't mean trouble ain't going to happen

TDK explained it well. Put an 11-87 barrel on it and never worry again about what you feed it....

thanks guys

That action was specifically made for 2 3/4 shells. I have an 1100 trap gun.
