Kurt, don't worry, it's not a headspace problem. The problem you have is a common one, thats how I knew what to answer the question with. For some reason some of the forearms tighten up on the gun, no biggy, I'd find out where it's binding and take it down a hair with some really fine sand paper. It's most likely at the rear of the forearm where the serial numbers are stamped on the wood.
The nay sayers that don't believe in this should have a look at the picture of Arthur Savage himself shooting one of his rifles with no forearm or buttstock on it.
