almost a problem?

[JohnnyK]

I'm getting my stuff ready for a trip to the range tomorrow... I have a bunch of .223 and 7.62 x 39... I was preloading some .223 rounds into mags for my Golani AK and noticed something looked weird... somehow a 7.62 x 39 round got mixed together and was already loaded into the .223 mag... if God forbid I didn't catch that what would have happened had I loaded that mag and started shooting?????

would the size difference cause the bolt to not close all the way making me catch the mistake before pulling the trigger? if some how, it did close, I know a 30 cal 7.62 x 39 round won't go down the barrell... am I right???

i'm also considering getting a AK-74... what is the size difference between .223 and what would happen if one were to mix those rounds together? not that I'm planning on doing that... but just curious... thanks... Johnny

No way it would have chambered and the head of the case won't fit into the bolt-face so the firing pin could never hit the primer.

The two rounds are nearly identical in overall length and diameter but the cases are different lengths. If you put a .223 in a gun chambered in 5.45 the chamber might not be able to close all the way. If it did manage to fire you'd be in a little trouble too, the bore (is that the right term?) on a 5.45 is just a little bit narrower than on a .223. If you put a 5.45 in a gun chambered in .223 the chamber could probably close all the way. But I think the round would be sitting in there loosely enough and far enough forward that the firing pin probably couldn't strike it. If it did go off the bullet would go down the barrel, it would just keyhole badly.

7.62 x 39 round mixed into the .223 mag

Hang up the cell phone and pay attention while loading mags?

I can't even imagine any way I could put that different a caliber round in a magazine, unless I had already suffered a head injury in combat!!

Comparing the 5.45x39 and 5.56x45, the Russian round is 0.4mm larger in case diameter and the NATO round is 5mm longer to the datum line. The Russian case is too fat to fit in the NATO chamber and the NATO round too long to fit in the Russian.

My son loaded a 223 round in my ak mag and it chambered an fired. Would not work the other way around, to big to chamber.

I have thousands of rounds of brown bear in both calibers next to each other... and they look similar in color... no excuse but it's what happened...

Well, it just goes to prove, Ole Murphy is still out there..
