Title: Ammo Question 7.62 X 58
Post by Klawbohr on Jul 11^th, 2012 at 5:05pm

I was given 2 boxes of ammo from a friend who inherited them from his grandfather.

Any help indentifying and perhaps value?

Cartridges are marked:
*FNM*7.62*58*

Thanks in advance

FNM is a headstamp used by 2 different ammunition producers; Fabrica National de Municiones in Mexico and Fabrica Nacional de Municoes e Armas Legiras, Moscavode, Portugal.

My guess is that the cartridges cases are military .30-06 ammunition made in Mexico in 1958. What the loads might be is anybody's guess.

The cartridge cases might be 7.62 NATO, but 1958 is pretty early for that.

Any chance it could be 7.62 CETME? (Which would be dimensionally more like .308 / 7.62x51 NATO.)
Or, does it look more like .30-06?

A picture would help. Especially if it's of the cartridge, not the box. Coincidentally, 7.62x58R would be the proper metric designation for the 30-40 Krag. Just like 7.62x63 is metric for the 30-06. Are the cartridges rimmed?

I was pretty sure myself that 30-06 was 7.62x63 also... 7.7 Jap is actually 7.7x58. Could this be a cartridge that was chambered to feed in a Type 99? The case dimensions for 7.7x58 and US M2 Ball (30-06 or 7.62x63) are very similar... and before Norma started mass production of 7.7 jap ammo, most Arisaka shooters made cases by trimming and re-sizing 30-06 cases. Also, .30 caliber jacketed bullets are typically .308 diameter, while 7.7 (and brittish .303) bullets are .312 diameter, so technically, a .30 caliber bullet could be fired in a Type 99 Arisaka if the case dimensions were correct. Food for thought????

The Mexican Army adopted the .30-06 as standard after WW2, after they retired their 7x57 rifles & MGs. Their M1954 (Mexican) Mausers were .30-06. And I have quite a bit of FNM .30-06 brass. Most of it is headstamped "FNM" and a 2-digit year, just like the US military stuff, and uses regular Boxer primers. I think the "58" is just the year of manufacture.
