[QUOTE="Wildboar, post: 905957, member: 39708"] Why was your rebarrel a disaster? Because you couldn't use your fired brass? One of the isssues with belted Magnus is fl sizing. I know people are going to come down on me for this. When the cartridge gets fired it expands, when we do resize we push the brass back down towards the head. Unfortunately there is a belt that prevents the die from sizing all the way to the case head. This eventually enlarges or expands to a point that you cannot chamber your brass any longer, no matter how far you push the shoulder back. There is a collet die specifically design do this issue. So as is my practice now, is I neck size my .300wby the first two firings (it saves a ton of time not having to lube and clean every time you reload) bump the shoulder back with the fl sized on the 3rd then collet size the base, anneal, fl size, repeat. Shoot until primers won't seat, around 6-10 firings. [/QUOTE]
