I would never exceed 45000 lbs of chamber pressure in a Spanish Mauser. Spain has never designed a rifle in 308 NATO. They had a round of their own in 7.62mm. Please consult Small Arms of the world. This also includes the CETME which was imported and placed into a American receiver.

I disagree to some extent. The CETME Model B was designed around the 7.62 NATO round. They made a special bolt carrier to shoot the earlier low power 7.62 X 51 CETME round.

Remember, there is no such thing as a ".308 NATO". It is 7.62 NATO or 7.62 X 51 NATO. I hate to be one of those nit pickers, but slight variations in nomenclature can mean large differences in performance and pressure. I would not want to cause someone injury because of imprecise verbiage.

I will disagree w/ this also. The FR8 is a large ring 98 action w/ a new 7.62x51 barrel. It is capable of handling commercial .308. It was designed using '98 large ring receivers and was to emulate the Cetme for training, sights and cartridge. Since 7x57 can have pressures up to 49000psi, the round the '93 action was designed for, were does 45000 come from??? It is PSI, not chamber pressure also. Not to nit pick.

You mentioned a model 93 and model 95 action. The 7 by 57 Mauser in those actions are approved to 45000 lbs per Ken Waters and Small arms of the world.
The information concerning the Spanish CITME is also in Small arms of the world.
Thank you for your comments.

The original 7x57 barrels were re-bored for the 1916 and FR7, they were still proofed for 49,000 psi which is for 7x57. The 1916 is a slick little rifle w/ the correct ammo.

Sarge, can you clarify what M95? The M95, Model of 1895 Styer was 8x50 or 8x56r. I understand these were never converted to 7.62x51.
That would be the same as the Chilean Mdl. 95. Not the Mannlicher which was not made by Mauser.

I too have read a lot of various things on the Net regarding our Spanish Ladies.
I have no problem using both surplus 7.62X51 and commercial .308Win in my FR8 rifle. I do NOT subscribe to the old "soft Spanish steel" canard. I DO check my bolt lugs for setback often.
My old M43 Mauser in 8X57 is dated in the 50's, as is the action of my FR8. The M43 I have been shooting since I bought it in 1976 - never seen any problems.
My FR8 and M191 are more recent acquisitions - I check them often too. I load 7.62X51 for both - full power GI spec for the FR8 and CETME, and lower-pressure loads for the old M1916 - just to be safe. I keep the lighter loads marked specifically for the M1916.
On another forum, a member in Spain with Spanish Army experience provided a translation of the Spanish manual for the CETME - it indicated they used 7.62X51, as made in Santa Barbara, Spain. This is NOT 'NATO' spec ammo, but then neither is the South African or the Australian ammo I have stocked and shot. All perform very similarly, and are of similar accuracy. I see little difference in POI between them - so their loading standards appear to be similar.
I think much confusion comes from Century and other importers stamping these rifles as '.308' when they are NOT.

My Spanish Mausers......
(The M43 Airforce Model in the middle currently wears a shortened Brazilian '08 stock)
