I purchased a 300Wm from a close friend , and it fired one box of remington ammo , I was there when it fired those 20 rds , since I purchased it , it has missfired 14 times in 100 rds . I was thinking primers , but I loaded for several different rifles from that same batch of primers and havent had any misfire . I suspected the bolt was dirty internaly so I gave it a serious bath with brake clean and lubed it with remoil , same result 15 misfires outa 100 . Im leary of takin the bolt apart ,after watchin my smithy put the bolt back togather on my 358 NM . Has anyone had a cci primer problem or bolt problem like this , I have 3 other M77's and havent ever had a missfire.
Thanks in advance
