"...Wonderful QC at Cabela's..." Cabela's manufactures nothing. They buy stuff and have their name slapped on. Same as Sears and all the other department stores did eons ago. And that 'combo' very likely did come from Remington with the scope mounted. Cabela's likely didn't even look at it.
As I recall, Remington has had all kinds of issues with their latest entry level hunting rifle called the Model 783. It's apparently nothing more than a variation of the Marlin XL7.
"...Where is your lapping bar?"..." You may want to look into what 'lapping' entails. It has nothing to do with mounting a scope.
"...Sierra Game King bullet that key holed..." There are several reason for key holing. Wrong bullet diameter, usually undersized. An oversize barrel, for whatever reason. Excessively low velocity. And in the case of cast bullets, a lack of lube.
