Any Remington 600/660/673/Xp-100/Xp-100R/XR-100/Seven/722/721/700/40X of OEM design are COCK on OPEN when rotating the bolt out of battery.
Pushing fwd/cycling the bolt into battery utilizes a COCK on CLOSE to reset the trigger/connector/firing pin striker.
STRIKER TO SEAR HAND OFF can be re-worked to operate by means that you have been lucky to have not had an accidental discharge to date.
(stop practicing that maneuver before someone gets hurt/killed & wants to sue Remington for being stupid)
Bolt Handle TIMING has nothing to do with firing pin cocking or trigger group operation.
The biggest variable w/ any Remington is the bolt body "TUBE" length prior to pinning & induction brazing the head/lugs to the tube.
The second variable is the changes in bolt handle design from 1962 to present.
Current production "short cam" bolt handles as I've coined them, can NOT be TIMED properly by silver brazing the handle closer to the receiver since there are 5 aspects to TIMING a bolt & handle.
