Well fellas, after a long hiatus I have crawled back into the hide. I picked up a neglected old Remington 700 7mm magnum and I noticed that one of the bolt lugs doesn’t have the usual cut out. And this rifle was manufactured in August 19 67 and has a six digit serial number. I’m comparing it against several otherRemington 700 rifles both long and short action that are all letter and 7 digit serials. Does anybody know the history of the change in the receiver in corresponding cut in the lug?
