.223 Remington vs. 5.56 NATO: What You Don’t Know Could Hurt You

He said they use .308 bolt and M-16 exclusively unless they need to shoot through a car or cinder block then they use 50mm.

Yep. The 50mm should do the job ..

[ataDude]

Heh, heh. Yeah, a two-incher will do it every time.

The military requirement for the bullet crime, like the primer crime, makes the military case about a hair longer after it is fired. That is it, cutting the primer crimp out and trimming to length fixes it. But it is much easier to reload by buying new brass. I shoot a 222 a lot, it is much more accurate, 788 Remington long barrel, tack driver.

For safety’s sake, you should use 7.62*39. :-)

I have a couple of Bushy’s and a lefty Stag for my son who is a southpaw. Couple of Armalite’s (AR-10’s) as well. Good weapons all and properly set up.

You’re right about stepping up and buying ia quality weapon of you don’t have any skill/interest in gunsmithing.

I’ve built a couple of AR’s for fun (out of stuff available from various manufacturers) and they were OK weapons but never performed as well as the factory stuff. Converted them to .22LR for plinking.

...although some are stamped 5.56 Rem on the receiver – are manufactured with .223 chambers.

Lower receivers don't have a clue what's barreled on top of them. Look for barrel stampings.

[gundog]

Now the Spanish Mauser 95’s are another issue.

I thought it was '93's. The 1916's that were converted to 7.62 CETME(from 7x57), post Civil War. I've shot 7.62 Nato in mine. Difficilt to lift the bolt, and it hits high. Reloaded for it with 110 grain light loads, but haven't fired it.

Meh... Hobbled 3.08 is still a hobbled .308. If you want to sling a bullet that big, go with either an M1A or an LR-308.

[Georgia Girl 2]

Yes we have some plinkers also. Guns are fun.

[SIDENET]

Meh... Hobbled 3.08 is still a hobbled .308. If you want to sling a bullet that big, go with either an M1A or an LR-308.

I sure likes me some Mosin Nagant, though.

That's not to say, however, that I don't have a M1A purchase in the works.

;-)

[Dead Corpse]

Hhmm... Now there’s a thought. Can an M1A be re-chambered for the 7.62x54R and would it have a positive impact on long range accuracy?

[SIDENET]

Don’t know, but it would be a heck of a lot cheaper to shoot.

[6ppc]

Sounds like a chamber cast is the only way to know for sure.

[Dead Corpse]

The differences in case dimensions and LOA are pretty close. The ones I'd be most worried about are LOA (about 7mm diff), bullet diameter (true 7.62 vs 7.82), and base diameter (about .4mm diff).

Would there be enough machining room and stroke adjustment to get the action to shuck the extra 7mm length?

Would the extra case capacity translate to a bit more velocity/accuracy? Could tighten up the twist rate, but then short range accuracy might be impacted due to the bullet waiting longer to sleep...
