Sounds like the shoulder is not pushed back enough to allow easy cycling. I like to push back the shoulder at least 0.002-0.003 to insure the rounds feed flawlessly. I know a lot of folks out there swear by neck sizing but when you are at 10,000 feet and something brown and hairy is in front of you, it better feed perfectly whether it is an elk or something with teeth. Interesting enough, the guys at Sinclair full length size their bench rifles so if it is good enough for them for bench work it should be good enough for hunting. I use the Stoney Point headspace gauges to set up the sizing dies and it works great. Each lot of brass will have a different springback and even from Win to Rem, the brass springback is different so you need to set your sizing die every time if you want to be in the 2-3 thousand setback every time. Is it anal? I don't know but I do know the brass lasts longer, the brass is consistently sized for your chamber which is always good for consistent accuracy, eliminates a variable when chasing down load performance. Using the cam over approach for setting the sizing die is not a consistent way to size brass for best accuracy and suggest looking at the Stoney Point of Sinclair tools to more accurately set the sizing dies. Just my 0.02.
