[QUOTE="Rardoin, post: 2431845, member: 114954"] ^^^ particularly on these short mag ‘fat’ bodied cartridges. If your brass is a bit short of the chamber’s shoulder and the load is not light on the first hit the brass can slam back against the bolt face producing ejector marks. The brass will also ‘swell’ at the base above the web and produce heavy bolt lift and clicking. I suggest dropping the load a few grains and shooting a couple of pieces of new brass twice then trying the loads that had the problems and seeing if it reoccurs. If it does then I’d investigate the barrel/chamber neck. [/QUOTE]
