M1917 / P14 Firing Pin Protursion

[Jeff G]

I recently replaced the firing pin in my Remington P14 .303 and I am getting pierced primers. The tip of the of the original firing pin in my rifle was damaged. I read somewhere that the firing pins are not field replaceable and may require fitting.

The firing pin that I used is an original Remington P14 firing pin. It is not a M1917 firing pin that was converted to a P14 firing pin.

Does anyone know the correct minimum and maximum firing pin protrusion for a P14 in .303?

I can't seem to find "official" GI specs for the P-14. Why did you see a need to to change the original firing pin Jeff? Is the replacement pin a new & unused GI pin? If your original pin worked, what was the protrusion on it? how does that compare to the new pin?

Why don't you post your question on the SMLE FORUM? Since the P14 is a British rifle, maybe someone there can answer your question..

For the 1917 .060 is ballpark. They used a striker protrusion gage with .050 on one end and .075 on the other. With the pin in firing position the .050 should not pass over it and the .075 should.... meaning between .051 and .075.

To add to the confusion, here is my P14 "field tool".
The markings on it for firing pin protrusion are .05 min, .055 max .....

From the M1917 handbook, the early guages were max=0.068 and the minimum = 0.058. This was later changed to Min= 0.050 and Max=0.078. This is for use with 30-06 ammo and the American Boxer Primer. For the P1914 the standard British ammo used a large Berdan primer and the larger protrusion may be too much for the British ammo. If one were to reload US cases with US primers perhaps the US demensions would be OK. For British Berdan primed ammo I would wonder if the deminsions published by DAD might be better. The protrusion on my Winchester M1917 bolt is 0.060.
Just a thought.

Funny , I could swear the gauge reads .04 and .055 .
May need new glasses.

Emmagee, I think I picked up my glass's from the same place you got yours. My left lens is off though, I see .053.

Here is a closeup, of the firing pin gage markings on the P14 field tool. :icon_redface:
No glasses needed this time.... :)

Thanks for that. Man , they kept the specs tight on these .

Emmagee,
If you think those specs are tight, take a look at the equivalent tool for a SMLE.
The min/max pin protrusion are .04/.042.....
