Yes, there is some history in this area. I'm talking guns that left the factory in the last years before the new ownership of Winchester. I have a 'Classic Compact' in 243 that had the same problem. The worst was going from fire back to safe I thought. It's the household 'youth' rifle & was rather difficult to move. I have a 70's vintage and a 10 or so Y/O model 70 to compare it to. It was so hard I was worried about breaking the safety lever. I had my ways but my Son had an issue with it.
I ended up sending my barreled action to Lee in N WI. He goes by 'Redneck' on the 24hourcampfire forums. He somewhat specializes in model 70 and was familiar with the issue. It was rather inexpensive,quick, & he checked out the trigger also. The safety did come back noticeably better, but still not as smooth as my 70's vintage 308.
