Hi,

This is off of the cabelas website, but can also be found in the Remington printed catalog.


"The 1100 Steel Shot barrel can be used with non-magnum receiver, you can shoot 2-3/4" magnum lead or steel or 3" mag. steel shotshells. DO NOT USE 3" mag. lead. Used with a magnum receiver, you can shoot 2-3/4" mag. or 3" mag. steel or lead shotshells."

Basically, if your friend has a 12 gauge Magnum receiver (should say magnum on the side of the gun) he can shoot 3 inch lead. If he has a standard 2.75" receiver, he should not shoot 3" lead shells.

I have both a 12 and 20 gauge magnum 1100 that will shoot 3" shells. Luckily I also have extra 2.75" barrels for each.

I have an older 1100 with a 30" vent rib barrelthat is 3" .It will only cycle premium ammo .It likes the remington Premier best.It does not like cold weather .

I own a 1100 LT-20. It is 3" Highbrass only! I can shoot 3" lead shot out of it for upland bird hunting but that is way to expensive. I use it for duck hunting only.

My father has 2 1100's that are magnums. They both fire 2 3/4 and 3 inch shells with no problems. There was a couple of years that Remington made the 1100 in 3 in. models. I have gotten in many arguments with people cause the insist that his guns are the 11-87 because they fire 3 in. shells. But they are both 1100's and fire any 2 3/4 and 3 in. shells we can put in it.

My father had on old 1100 that shot both 2 3/4" and 3" shells
