A few ammo questions from the guy who wants to learn more

[Aaryq]

Okay folks, the next round of questions.

The AK-47, M-14, Mosin Nagant, Dragunov, SKS...etcetra: They're all 7.62. After that you have X54, 39, NATO...what does that mean?

Second question: 30-30 and 30-06. Both .30 caliber right? What's the difference between them?

I know there is a difference, what is the difference?

 

[Bazooka Joe71]

7.62x 39=.311
7.62x 51=.308
.30-06 =.308
.300 winmag=.300
7.5 swiss=.300
.303Brit=.311

Please don't flame me if I'm off a bit, but I think that is what I was told.

Second question: 30-30 and 30-06. Both .30 caliber right? What's the difference between them?

Length of cartridge

nato=mil-spec

Second question: 30-30 and 30-06. Both .30 caliber right? What's the difference between them?

In a nutshell, the .30-06 has a larger case than the .30-30 and, in standard configuration, is more powerful than the .30-30. They are not interchangeable.

 

[Aaryq]

No flame here...especially since I worded the question. So 7.62mm is give or take (I'M NOT THAT MUCH OF A DUMMY TO PUT 7.62 IN ANY GUN THAT SAYS 7.62) and the difference is more in casing size...could you elaborate as to numerically why they have the various designators by them?

As to the 30-30 and 30-06 question...what's the difference in their usage? When would you use a 30-30 compared to when you would use a 30-06?

I'm not quite sure I understand this question.

 

[Hoppy590]

yes, length of cartridge. but also the 30-06 is rimmless, the 30-30 is rimmed. the bullet they fire is very differant.

any number with an R after it is a rimmed cartridge, such as 7.62X54R or 7.62X38R ( Nagant revolver)
ANY IMPLICATION THAT THE R STANDS FOR RUSSIAN IS WRONG! 7.62X39 IS NOT 7.62R


that 30-06 is 7.62X63 in metric type measure. or .30 caliber year 1906 Springfield, hence the 30-06. where as the 30-30 (7.62X51R , NOT the same as 7.62X51) is originaly a Winchester round, where the second 30 was added by marlin so they dont have to put a competators name on thier gun.

honestly, 30 cal arms in the gun worlds greatest can of worms. theres alot of differant styles and origins. DONT THINK OF THEM AS HAVING A STANDARD SYSTEM. they are all crazy, a 7.62x51 is considered to be significantly more powerfull than a 7.62X39 but a 30-30 (7.62X51R) is considered comprable to the 7.62X39 ...

In the words of one Wascaly Wabbit.
Screwy, aint it?

 

[Hoppy590]

oh and to add to the confusion heres soem you missed
7.62 x 25 ( tokarev pistol)
and
7.62 x 33 (.30 Carbine, US M1 Carbine)

As to the 30-30 and 30-06 question...what's the difference in their usage? When would you use a 30-30 compared to when you would use a 30-06

30-06 is MUCH more powerfull. and has a much greater range. 30-30 is a close range round, suitable for deer 150 yards and in from my understanding ( im no hunter, so take that with some salt) the 30-06 is capable of taking deer from greater ranges than you will probibly get. 30-06 is also suitable for larger/more dangerous game like bear and maybe moose ( still not a hunter)

and the difference is more in casing size...could you elaborate as to numerically why they have the various designators by them?

yes, but remember thats only a number. it doesnt describe the shape of the cartridge, the slope of the shoulder, the headspace, the style of round meant to be fire. ONLY use the right round. even if it may seem one number off, 7.62x38R is not interchangable with 7.62x39

 

[funfaler]

If the caliber is 7.62x (some other number) the other number is the length of the cartridge. So 7.62x39 is the 7.62mm diameter bullet by 39 mm length cartridge, the 7.62x51 is 7.62mm diameter bullet by 51 mm. These are Nato and/or military designations/descriptions.

30.06 is an US term for 30 cal bullet designed in 1906. 30.30 is the same type of designation. the 30.06 is 7.62x55, I think and is nearly the same as 7.62x54 from Russia.

7.62 Nato is 7.62x51 which is what you and I call 308 Winchester. There are some important technical differences between 7.62x51 and 308, but you can't tell by looking and for the most part, they are interchangable. The only problems are when you are reloading or shooting in rifles specifically chambered for 308, like the DPMS 308s

I hope that gets to your question. Some of the actual bullets might be interchangeable, but the loaded ammo is not.

 

[funfaler]

30.30 and 7.62x39 are nearly identical in balistics and power. Both would be considered an intermediate power round. And both are very capable hunting rounds for Whitetail deer and down, out to @150 yards, and a max effective range of about 300 yards. 30.06 and 308 are full power rounds, with an effective range in excess of 600 yards.

 

[dubious]

The Moisins use 7.62x54R which I believe is slightly more powerful than a .308 (7.62x51) but slightly less powerful than a 30-06. I think its closer to .308. It's certainly nothing to be trifled with.

Also much 7.62x54R is corrosive (unless your sure it's not), so be sure to run a watered wet patch through your barrel IMMEDIATELY after your done shooting, in order to dissolve the salts. Push it straight through and don't pull it back in. Then do a normal cleaning with your normal cleaning product when you get home. Oil based cleaning products don't dissolve the salts, so don't think they'll save you from a rusty barrel.
