Ammo quiz...ID all the calibers shown here

[c00nhunterjoe]

9x18?

[Rolling_Thunder]

extremely close...    but no.

[vancamp]

9x19

[moparguy01]

Nope. Number 2 is 556. 

Actually its not, its stamped .223 although technically the same it is a .223

Actually they aren't. 5.56 and .223 are slightly different in case length. Hence why you can shoot a 223 round through a gun designed for 5.56, but not a 5.56 through a gun designed for a 223. Trust me. I make this ammunition, the case is not the same.

Man, I'm making it too easy. Great guess, its. 16 inch naval gun used for coastal defense. It was origonally built for a super batleship. The battleship was never built due to weight restrictions so the guns were placed around the states for shore defense.

Hmmm interesting. But they had 16 inch guns on other battle ships, wonder why this one wouldn't fit?

ding ding...    that's why I have a 5.56 upper on my AR - not the way too common .223 model.   

[Rolling_Thunder]

9x19

It is 9x19...    however it is not the common Parabellum --  any other guesses?

[c00nhunterjoe]

Then its the russian tokarev

[ACUDANUT]

 Some of you guys are nuts. 
.223 is a 556 and visa vera....I have many AR-15's and I use a US Gov. M-16 FOR MY JOB....They are the same round. We mix and match ammo up all the time..It does not matter. 
.223 is a US Caliber...556 is a Nato caliber....SAME THING.
308 is a US Caliber...7.62 is a Nato Caliber...SAME THING.
Peace out.

Quite the oppositte. Externally the 2 rounds are the same, but a 556 case is much thicker due to the higher pressures used in it. If you reload 556 brass using a 223 load chart you will risk blowing out he case and risk injury. Also, the guns are physicly different. 99% of the time either round will chamber in either gun. BUT a 556 has at least double the throat of a 223 rifle. That means that if you put a 556 round into a 223 rifle there isn't enough room for the bullet to travel before contacting the rifling, thus risking an overpressure situation which culd blow out the primer,or worst case, blow up in your face. Firing a 223 out of a 556 doesn't matter, you will have lower velocity and possibly marginal less accuracy.  Paying more money for a "multical" ar15 is a rip off as well, they are just a 556 gun stamped "multicaliber" for those consumers that don't know.  Just buy a 556 rifle and you can safely shoot either round.

I'm not savvy on this 5.56 vs. .223 debate, but I've used .223 remington and Lake city 5.56 reloads in my AR and M-4..never had any problems.

So what about .308 vs 7.62x51??

[c00nhunterjoe]

Its the opposite with 30 cal. Safe to shoot 7.62 in a .308, but don't shoot 308 in a 7.62 gun. 2 reasons. 1st, the 7.62 gun has a larger chamber then a .308 gun. 2nd, a .308 is a thinner case with higher pressures. 60,000 vs 50,000 or less in a 7.62 round.

It you fire a .308 in a 7.62 gun the .308 cartidge will expand to the larger chamber and can rupture causing catastrophic failure. Will it happen every time- no, but it can and does happen.


The 556 vs 223 debate isn't as dangerous a swap as the 7.62 vs .308. The safety factor built into the rifles to deal with overpressure will typicly take the potential abuse from the difference in the rounds. The bigger risk of failure comes when you reload a 556 brass using 223 charts.

[Rolling_Thunder]

Then its the russian tokarev

Negative...      it's another type of 9mm round...       Think Europe.

Luger

[c00nhunterjoe]

Lol, no quick comments on the luger reply???


How about the glistenti round? I don't know of any other 9x19. What do you have that you are firing that round from?

I'm sorry. You must be right. Its not like I work in the factory making those particular rounds and checking their specifications for 12 hours a day. My mistake.

[Rolling_Thunder]

Yep -  9mm Glisenti       

[c00nhunterjoe]

So where did you get it? What gun are you shootng it through? I am quite interested.

[c00nhunterjoe]

Alright, time to step it up a notch......... I fired all of these

[68blue]

9mm Glistenti is an Italian cartridge about on par with the old Colt 38 ACP. It was manufactured because of some Italian law that barred the use of military ammo for civilian guns.

[AKcharger]

I can only get a few, starting Right to Left:
- .45
-7.62x39
-7.62x54R
- I don't know
- 30-06AP
- 30-06 (not sure what kind of bullet though)
- .50 cal
- I don't know
- 20 mm
- 25 mm (thanks for the hint)
- 30 mm?

[c00nhunterjoe]

Very good! Not completly correct.
Your 2 labled as 30.06 are incorrect, however extremly close. And obviously the 2 " I don't know"'s are still up for identification. Bonus points for the round to the left of the 30mm

[69rtse4spd]

105

[c00nhunterjoe]

105

Excellent! 4 rounds left to be identified.
