Firing Pin 91/30
Firing Pin 91/30
Hello everybody!
As this is my first post in this forum I want to say and thank you in advance for your help! Yesterday I bought my first Mosin Nagant 91/30, therefore I´m quite new ...
As I already told you, I bought the Nagant yesterday. The first thing I did was disassembling the rifle and cleaned it completely.
Now to my problem: before the first shooting I want to be sure that the firing pin has the correct position, there is a gauge to measure the distance. Can anybody tell me the dimension (in mm) how far the firing pin should look outside? I´m not able to buy this gauge in Austria, therefore I want to measure it with a calliper. But I was not able to find this dimension in the web.
I´m sure somebody of you owns this tool, maybe you can give me both dimensions, of "go" and "no go" ...
Thank you so much for your answers!!
Best regards from rainy Salzburg,
Heinz

Re: Firing Pin 91/30

Re: Firing Pin 91/30
Thanks for your help! Is it really inch??
Re: Firing Pin 91/30
You are talking about two different things. The .075 reading is the reading that is correct. The firing pin should just brush this. If the pin touches the .095 reading, the pin needs to be adjusted back. .075/.095 are not inches but millimeters. This may be difficult to accurately measure with a caliper but I have never tried it. Go and no-go usually are used to reference head space which is something that needs to be addressed. Click on "ID Marks and Tecnical/Cleaning" above. Also JYD does have some videos on this as well.
We are not a bad lot of people here. PM me your name and address and I will send you a gauge.
Oh... welcome to the forum

Re: Firing Pin 91/30
The tool actually says "75" which I take for .75 which is more like .03 inches which sounds more like it.ParrotHead wrote:.075mm = .003"qz2026 wrote:You are talking about two different things.

Re: Firing Pin 91/30
i think 0,075 inches is correct, which means 1,905mm. Now i measured the firing pin, and it has 2,21mm so 0,087 inches, which should be fine? Right?
Re: Firing Pin 91/30
one more thing: could anybody be so kind and measure this two dimensions on the tool? Just to be sure...
THANKS

Re: Firing Pin 91/30
How many time do we need to do this?
.095" No more then .095" (does not touch on .095")
.075" No less then .075" (should "rock" on .075")
.095" No more then .095" (does not touch on .095")
.075" No less then .075" (should "rock" on .075")

Re: Firing Pin 91/30
.075" is obviously correct. .750mm = .027" which is just not possible.
I just measured my tool below. You can clearly see they are .075" + .095" respectively.

Re: Firing Pin 91/30
it is inches, I test all my Mosins with a micrometer.

1,905 mm's?? That's one Helluva protrusion considering there are only 25.4 mm's in an inch. 1 mm=. 03937''ThePeltin wrote:i think 0,075 inches is correct, which means 1,905mm. Now i measured the firing pin, and it has 2,21mm so 0,087 inches, which should be fine? Right?

Re: Firing Pin 91/30
Totally going to threadjack here, Happened to browse past Junk Yard Dog's guide yesterday, and then saw this topic today.... so I thought I midas well make a comment.
A thousand rounds + later, i'm yet to have a puncture. Completely bottomed out, my firing pin still touches the 95 (tool will actually veryyyyyy slightly wobble on the 95 reading.)
Same pin that she was imported with, and she's not given me a single issue to speak of.
Y'all think this is something I should address with a new pin?

Re: Firing Pin 91/30
Basically this is a tool called a go or no go gauge. It basically goes through the larger setting and doesn't go through the smaller setting. Anywhere in that range using the go or no go gauge is right not just one reading of any size or length. If you have a bunch of these go or no go gauges you will also find if you check them with a vernier caliper like one poster above did they vary a bit too. That indicated to me that this setting does not need to be microscopically perfect, indeed many people say they don't even check this but use the line scribed on the back of the cocking piece and the line in the firing pin lining them up and making the firing pin flush with the cocking piece. I don't recommend this as I have had a few pierced primers in my lifetime and they will tend to scare and could hurt you.
This is basically a very simple and straight forward rifle using parts that are simple to measure and assemble with parts from a basic cleaning kit. Most of us don't have calipers and expensive measuring tools so this rifle is ideal for us to collect, maintain, and shoot with what basically comes with the rifle. Go or no go is much easier to understand for most without getting into .75 or other numbers, Myself I am well passed the age of being impressed by figures and such just give me something clean and safe to shoot and I am a happy camper!

If you're worried about it, back it off one full revolution, and It'll be in spec.

She's fully bottomed out. To turn it any further, i'd be causing damage to the shaft, creating new threading...entropy wrote:SSGTSemperFi wrote:Totally going to threadjack here, Happened to browse past Junk Yard Dog's guide yesterday, and then saw this topic today.... so I thought I midas well make a comment.
