I took this gun out to the range the other day with some Yugo ammo. The firing pin hit the primer but two didn't fire (in a row). Sooo I quit right there. Was reading on line an it said surplus yugo ammo needs a good hit. Checked my firing pin protrusion with dial calipers (three times) have .032 (thirty two thousands) I don't know if thats enough or not. Do I have to buy gauges to check all this out ? Or should I increase it an try again? just lookin for some opinions

Well guess nobody has any ideas here. Is there away to check headspace without a gauge? Lenin: The best way to control the opposition is to lead it ourselves

I'm not a Mauser guy, but 0.032" sounds a bit short. Probably up to 0.060" would be better.

yeah I wanted to ask before I go stoneing or fileing on the striker. Have a book coming but just wondered if my problem could be that the cartdidge is to far into the receiver due to wear. Is their a way to check this besides gauges? I am new to all this but have some machinist experience and a very old lathe that works.

You might check to see if there isn't a lot of cosmoline in the bolt causing the bolt to lose thrust. Happen to a friend of mine with two new/used Vz24's he tried shooting for the first time. The bolts were packed with cosmo, Ray

Yeah ....Cleaning was all that was in order. Now that is cleared up. I have a Spanish Mauser 1916 civil guard emblem on the receiver. It says Cal 7.62 on the side of receiver. On the bottom of the end of the barrel is a vermont import mark and it says 1916 308W. By these marks I am thinking it is chambered for the Nato 7.62. I took a 7.62 round an inserted the bullet end of this live round in the muzzle it left a ring on the jacketed round that mic's .302. the bullet right up close to the neck mic's .308 That works out to a very tight barrel on that bullet is this normal ? This is a starrett mic calipers I am confident of my measurements. any thoughts

The Spanish Army used a special 7.62mm cartridge for the carbine. It will fall apart if you feed it a diet of 7.62mm Nato ammo. I think (?) they used a 110 gr. bullet at around 2400 fps. A real download.

Carteach0: Mauser firing pin protrusion ..... solving a failure to fire condition
Here is a good write up on the process of checking out firing pin length. The process worked well for an old Turkish Mauser I was having trouble with.
Modern primers seem to work better especially in the cold. Surplus ammo seems to be a bit hard.
It is not unusual for me to have several cases out of 20 that need a second strike especially during Minnesota winter outings to the range!

One thing I think that Grandpa Rex's link doesn't check is f.p. protrusion w/ the cocking piece and spring removed, but I could have missed it.
Anyway, if the bare pin's protrusion is at spec. or greater, this method ought to work. Otherwise it gets a little more complicated...
