The RST Lites (7/8 oz) that I have are marked 2 1/2 " and 65 mm (closer to 2 9/16)on the box and the hull.

65mm ~ 2 9/16"
67mm ~ 2 5/8"
70mm ~ 2 3/4"

"Again, oddly, the 16 gauge short chamber guns don't eject 2 3/4 inch shells very well in my experience."

My Mod 12 16ga is 2 3/4" factory-chambered and still has trouble ejecting most 2 3/4" shells. There's quite a variance in hull length among nominal 2 3/4" shells...maker to maker...and even lot to lot.
