Absolutely it can without issue.

yes it will work with 2 3/4, 3 and 3 1/2 inch shells

It will shoot 3.5", 3", and 2.75" shells without issue.

Absolutely, it will cycle 2 3/4, 3 in and 3.5 in. Shoot safe!

Hi Shawn and welcome. Yes Sir. The Super Nova has a 3.5" chamber so it will fire 3.5-inch, 3 inch and 2 3/4-inch shells no issue. Same concept as a .357 Magnum being able to fire the shorter .38 Special. Cheers and stay safe!

Hi Shawn, the Super Nova has a 3.5" chamber. This means it will shoot 3.5", 3", and 2.75" shells.
Stay safe & have a great day!

Yes.

Good evening to you!! The Super Nova will accept both 2.75 inch, 3 inch and 3.5 inch shells with no problem. You will need to cut dowel rods to make it legal for hunting when you use 3 and 2.75 shells. Hope this helps. Have a good rest of your weekend.
