So - my question is - is this a problem with the lacquered case ammunition? As in - the lacquer is sticking to the inside of the hot chamber?
Yes. There's probably ancient cosmoline and/or cleaning oil residue inside the chamber. Next time you take it to the range, shoot it until it starts getting hot, then wipe off the inside of the chamber with a small shotgun brush soaked in mineral spirits. A small rag tied to a piece of wood will also work. This procedure can also be done in a warm (180-200 degrees F) oven, but this requires disassembling the rifle and obtaining spousal approval.

It's also possible that you have a burr in the chamber, although this usually causes hard extraction right away, with a cold barrel. Inspect your extracted rounds for scratches. Be aware that the ejector on the receiver wall usually scratches the cases on the way in, so you'll want to hand-feed the test round(s) partway into the chamber.

Or is it possible that the action on my rifle is too tight? As in, when the metal parts expand with heat, they are causing the bolt to jam?
It's possible but quite unlikely.
