Primary Extraction Cam Surfaces

[Edd]

I was checking the fit of a new bolt in the receiver of a Remington Model 7 and noticed the cam surface on the receiver is not cut perpendicular to the receiver bore. It has a slope, top to bottom of about .020". The cam surface on the new bolt handle is cut perpendicular to the bolt body.

So, the bottom edge of the receiver cam is all that contacts the bolt handle cam. Is this something that needs to be corrected?
