I think that you will find the heads on the featherlites are washed steel, Knock out the primer and see if a magnet still picks up the hull. This will cause some sticking in many guns.

The Rem 1100 will not cycle the Featherlites, that is expected.
The pressure on the featherlites is still a bit higher than the SPECIAL Federal handloads.

Another possibility is the entire primer set back a bit causing the action to tighten up, A way to check this is ENSURE you fire both shells, then drop a cleaning rod down the barrels to impact the inside head of the EMPTY hulls and reset the primer against the action face. Does the gun now open easily?
