What stops the forward movement on a Remington 700 firing pin?

Not talking dry fire, but during actual firing on a cartridge.

Is it the primer? Is it the interface between the firing pin and the recess in the bolt? Or is it something at the back end of the firing pin, like the guide and bolt plug?

There is a limit to the travel, otherwise pierced primers would be common.

I was aware there is a limit to travel. The question centres on whether that limit is reached or not under normal firing, or whether the primer stops it short of that limit.

So in a normal situation, where say the firing pin protrusion is set to .035", when the gun fires and the firing pin strikes the primer, it goes to that full protrusion limit?

I would expect that the firing pin is very close to but not typically reaching a hard stop. In that case it would indeed be up to the primer. I won't lie, this is just speculation since I am far from a Model 700 expert.
 
Basically the firing pin hits the primer and drives the case forward until the shoulder hits the chamber... Unless the primer is abnormally hard the firing pin will be fully forward.
 
OP,
.035" firing pin protrusion in a Rem....nothing will go bang.

Check pin protrusion at breech face of the bolt-.050"-.060"

The firing pin has a shoulder at the forward end that has a purpose by design.
1.Aft end of shoulder preloads the mainspring.
2.Fwd end of the shoulder is the firing pin STOP.
3.The fwd face of the shoulder also acts as a GAS Check in the event of a blanked/pierced primer to divert high pressure gases from passing straight thru the bolt body.
( a hole in bolt nose @ 8oclock when in battery & a hole in the front receiver ring above stock waterline to VENT said gases)
