WRONG ANSWER.
(fix 10,000+ bolts/handles & get back w/ me as you haven't a CLUE)

Primary Extraction has NOTHING to do with firing pin cocking on any bolt action.

Once you rotate a Remington bolt handle out of battery you start to re-cock the firing pin.
(hint- that's what the cam surface is that's cut into the aft end of the bolt body.)
The firing pin STRIKER "detent's" into the radius cut at 6o'clock position.

Tip the rifle muzzle down w/ a cleared action.
Bolt slides fwd.
TAKE NOTE to how much protrusion you have from striker to shroud.

Push fwd & rotate bolt into battery.

TAKE NOTE to how much protrusion you have from striker to shroud.

Not my first rodeo

It's not Rocket Science


Keep'em in the X ring,
