7.62 NATO v. 7.62 CETME

[VVelox]

Any one know how 7.62 NATO and 7.62 CETME compare in terms of bullet drop?

Just found myself wondering if I sight in my FR8 at 100 meters how much the the other three will be off.

I didn't think the two were interchangeable, but then I may be wrong. Wouldn't be the first time today.

They are interchangeable, except for in the FR7 which is based of the small ring Mauser.

7.62 CETME is a downloaded 7.62 NATO round with a 113gr bullet that was developed for reducing the recoil in the CETME battle rifle to make it more controllable in full auto fire.

Ah cool, thanks.

Any idea what velocity it was downloaded to? With that and the bullet weight (that you already know) you can plug it into a ballistic calculator and get a pretty decent approximation of how it will behave.

VVelox: Some people state that the lower pressure in the Spanish Cetme rounds was designed to compensate for use in the Spanish Nato 7.62 bolt-action rifles, which were converted from the old small-ring 7mm Spanish Mausers.

At gun shows, guys selling such converted Spanish 7.62 bolt-action rifles don't mention (don't know, or don't want to lose a sale?) that these could be unsafe with modern .308 ammo.

Wikipedia has a write up on the CETME round and it's use in the assault weapon development of the day.
