Having gone over about a dozen RR prefix actions, only 2 of them were close to having contact between the bolt handle and primary extraction cam, others plain missed.
To get a proper look you need to take the firing pin spring and trigger mechanism out but a 'close enough' measurement is to drop the firing pin and see how close the bolt handle and reciever cam comes to touching when you lift the bolt handle to recock the bolt. There should be minimal clerance between the front edge of the bolt handle and most rearward portion of the receiver's rear bridge.
Supoosedly due to Remington changing the forging moulds which resulted in bolt handles having surfaces that did not work as well with the receiver's cam, followed by a change in process meaning the bolt handle was used to set headspace... not a good idea at all...
This is mostly gleaned from Long Rifles Inc (Chad Dixon) and his posts of Facebook and Snipers Hide.
I'm sure @gundoc would be a better person to ask about primary extractions and Remington rifles in general as I only own two and don't have experience of fixing a Remington bolt handle that has not been timed correctly (and then broken off...)
Just sharing what research I did before buying as I didn't want a lemon. Remington Firearms has great concepts and designs but their execution and marketing usually leaves a lot to be desired!
My SAUM was of the RR series, I suspect it was poor to start with I think (cant be 100% sure as it was never actually fired I believe before it got rebarreled for me) and only got worse once suppliers/gunsmiths faffed around with it. Who would have thought it was so complicated to fix!
I would not buy another Rem700 of late production ever.
