CBC 7.62x51

This is a discussion on CBC 7.62x51 within the Ammunition forums, part of the M14 M1A Forum category; It's hard to tell if it says 15, 13, or 75. What do you guys think?...

I magnified it digitally, it appears to be a 15.

Thanks from fragglestickcar

Believe me that leaves a lasting impression
You can keep your CBC just don't shoot it around me.

Read the 16th entry
http://www.firearmsid.com/Recalls/Ammo_Recalls%201.htm

Springfield Armory even included a warning about the hot loaded CBC in the green boxes of the early 90's,
right along with the headspacing tag. [My 88' didn't, my 91' did]
It blew up a number of battle rifles at the time. FAL's , HK91's , M1A's .
There was quite a flap about it at the time
I'm not saying anything but the 75' marked ammo is bad
BUT
I'll never forgive them or forget them

That said I'd save up just a little bit more cash and buy some better made ammo than CBC for a $1500 plus rifle.
What about Cavim from the 90's in green boxes? Made in venezuela.

Any reason why your LR-308 says to stay away from CBC?

None given. There are a few others it says to avoid.

But the LR is marked .308 Winchester , not 7.62 NATO , and there is no statement to stick with NATO ammo.

I've never used the Cavim , and as such am not aware of it's virtues or damnations .
Is there a problem with the 90's era green box Cavim ?

I tend to use roll your owns , and NATO surplus [primarily port],
and stay away from anything made south of the border except jalapeno's , beer & Tequila .

I understand that, but 308 Winchester marked rifles will fire 7.62x51 with ease. It's the 7.62 x 51 marked rifles that shouldn't be fired using 308 Win ammo! It's a case of "One is good for the other, but the other isn't good for one!"

I just loaded up 50 rounds of CBC brass that was shot out of my rifle some 3 to 5 years back they had the green primer sealant but no primer staking

Brass looks good to go to me... Marked CBC .308 Win

A good rule to follow is that if you have even the slightest suspicion that there is a possible problem with the ammunition, do not fire it in your rifle. Far better to be safe than sorry, but it's the individuals decision, choose wisely.

Thanks from JEFFJP_N_JJ
