I have a custom 6.5x55 shooting Berger 153.5gr using Lapua brass and 43.2gr of RL17 @ 2830fps from a 29” barrel. When my brass was virgin it extracted smoothly. I have found after reloading that brass I am getting clickers in varying degrees from barely noticeable to needing a tap of the palm to get the bolt to lift the last 20 degrees to open the action.
I do not believe it is a pressure issue, when the brass was virgin I shot ladders up to 44.5gr without any issues. I also loaded the once fired brass a full grain lower than my load at 42.2gr and still had the same issues with clickers.
My resizing procedure has been to push the shoulders back .002”. I also tried bottoming the die on the shell holder to the point of cam over to see if it was the base of the case not getting properly sized in these cases I had up to .010” head space.
I think the issue is the body not getting sized down enough but I’m not sure, all cases chamber with zero resistance when I remove firing pin and spring the bolt handle drops freely.
My next plan is to cut the top off a sizing die and mill .020” off the bottom so I can squeeze the body slightly smaller.
Anyone ever experience anything like this and have some advice?
