Well, the board is either fixed, or it's going to run terribly. Cross your fingers and hope for the best. I'm at my technical limit right now.

Safe ammo for 1916 spanish?

#1 Post by Kurt » Mon Mar 19, 2018 5:43 am

Sorry, I can't figure out how to delete this. I realize I posted in the wrong place.


Hello. I have a 1916 civilian guard Spanish Mauser redone for 7.62x51. I also have some 7.62x51 ammo marked LOT: 8-80 (?August 1980?). Headstamped TZ 80. Would this ammo be appropriate for the mentioned rifle? The rifle is in very good condition. I believe the ammo is Israeli but I am not sure? Would the primers be Boxer and non-corrosive? Any idea of the bullet weight? Thank you very much! Kurt

I would uase any quality 7.62x51 surplus

EXCEPT the TZ 80 mfg....this ammo is known for MANY cartridge case head failures with 52,000psi of gas dumped into the action on firing. I had 3 cases fail from the rim to the primer pocket shooting 100rds of this ammo. Google "TZ 80 case failure" or similar for other similar stories.

It is boxer/NonCorrosive but the defective cartridge cases are your primary concern.

ammolab. Thank you very much for your reply and the valuable advice. Excuse my request for clarification but you are saying, perhaps, "save the bullet and primer throw the rest away" ? Thank you again, Kurt

Just my opinion, but I think there is always cause for concern when shooting 7.62 NATO in a Spanish non-'98 Mauser. Those actions were designed for 7x57 pressures in the 42,000-46,000 psi range. 7.62 NATO runs up to 58,000 psi. The rifle will probably take it without incident but you are kinda pushing it on an older rifle. Better to drop a couple hundred fps by loading down, IMHO. WW748 powder is a good choice for this. 44.0 grains of WW748 behind a 147 or 150 grain bullet should yield about 40,000 psi in 7.62 military cases with a velocity of approximately 2,700 fps (this is a published load in the Lyman reloading handbook).

Commercial .308 Winchester runs as high as 62,000 psi and should never be used in these conversion rifles, or at least that is the conventional wisdom.

Normally, 7.62 NATO uses a 147 grain FMJ-BT bullet.

I should also note that some people have experienced poor accuracy with these conversions and have discovered upon slugging their barrels that they have bore diameters of .311". This is not a problem for reloaders (so long as there is no issue with chamber neck diameter) as 150 grain .311" bullets are readily available.

I will move this topic to the more correct Spanish/S. American/Central American/Mexican Rifles section where it may get more activity.

The cartridge cases have defective/fatal flaws in the brass. If you have the skill and need you could save everything BUT the cartridge case...up to you. BIG variation in velocity might rule out viable primer and powder in that ammo.
