I have a Model 8 35 Remington cal. It fires well and is very accurate but it has trouble cycling. Any thoughts on what might be the problem?

"Trouble cycling" as in how? Bolt stripping new round from magazine, chambering new round, ejecting brass. One or all three? Depending on the "trouble" narrows it down to cause. I'm fairly new to the 8/81 rifle, can understand some problems, but others here can really chime in on possibilities.
