As a Marine n Vietnam 67 to 68 I used the M-14, 7.62 NATO round, which I experienced also used the M-16 5.56/223 NATO round. Jungle battles in heavy foliage, tracers told the story of heavy rickoache from the 223 where 7.62 did not. No interferrance open ground the 7.62 had more knock down power, even though the 223 did nearly the same, but distance told a different story where the 7.62 took every hit as a knock down, where the 223 was not, and the enemy still wanted to fight wounded... The 7.62 they went down and they stayed down which saved lives. oora RC over and out. Reply with comment Banana... Short, medium, or Long range the 7.62 you don't want to get hit by that round period...

[@ThePaulv12]

I read a book on powerful weapons. The swap from 7.62 to 5.56 came up. The book explains theory of the 5.56. What the idea was, the 5.56 was more likely to wound than kill. If you wound that takes 3 people off the battlefield vs killing just one since apparently 2 soldiers are need to tend to the wounded soldier. Whether that's how it's ever worked is irrelevant to this discussion but interesting the 5.56 is still used. Lighter ammo weight allowing a soldier to carry more and ranges fought at is probably part of it.

[@garydouglas9413]

​@@ThePaulv12Carrying more of a lighter round results in more weight than carrying less of a heavier round. It takes 2 or 3 of 5.56 rounds to achieve the same result as one round of 7.62.

[@Rational_thinker_212]

If you are primarily a hunter, like me, the answer is simple. 7.62 is ok for practice but only comes in fmj or a target bullet. You gotta go with a game/species/size bullet when hunting and that means 308. I've shot over a thousand rounds of surplus 7.62 in my bolt guns with no problems except the occasional hard primer which went off the second time. Here's the summary that should have been up front.: 7.62 ammo is contract loaded for mil purposes. That means better weather sealing, harder primers to be more to resistant to slam fires in full auto guns, tighter bullet crimps -- same reason, and bullets that comply with Geneva convention legal battle requirements. Also full autos that fire from a closed bolt can sometimes cook off a round due to heat. Not something to worry about in any hunting situation.

I compared new Turkish import 7.62 NATO brass with new Starline 308 Winchester brass, the 7.62 NATO brass has about 2 grains less case capacity, I was using IMR-4064 powder for the test, 42.8 grains fits nicely in Starline brass, but crunchy and compressed in 7.62 NATO brass.

[@carnage77]

[@blackhawk7r221]

[@0529mpb]

Cases vary between manufacturers in terms of brass thickness and tolerance. Typically, a manufacturer that loads both will use the same cases and stamp them differently.

[@richardkudrna7503]

The NATO spec requires much more head brass against case burst. The reduced capacity hinders loads a bit but by tinkering with dense powder and slower burn you can probably match muzzle energy.

[@blackhawk7r221]

In hot open bolt machine gun chambers, we occasionally get ripped apart cartridge cases. Only the case head will extract leaving a brass “tube” that the next cartridge is fed and jammed into. Only saw it rarely with M80 7.62 240’s, but a few times with the smaller 5.56 249’s using M855’s. Makes for fun times pulling and setting aside a very hot loaded barrel to set aside and rod out later.

However, the 110 grain and 220 grain bullets have not been factory loaded in .308 for many years. Now, the best load out there today for long range target shooting from a 7.62 gas gun or a .308 bolt gun is the M118LR round.

OK I'm Amy 5 min into video and I will watch to the end :) But 7.62x51 is a military round as you know and it is designed for penetration, armor piercing and all of that. .308 Winchester is a more powerful round as it is factory loaded hotter than the mil spec for 7.62x51. It however is primarily a hunting cartridge and hunters are not typically worried about penetrating steel since I have never heard of a hunter encounter with an armored deer ;) Hunters do want good penetration but we are talking bone and muscle tissue and expansion is more important than penetrating steel your lumber demo clearly showed superior expansion in the .308 which of course means less armor piercing.

[@robmorgan1214]

It doesn't depend on the ballistic specs. It depends on the velocity and materials in the actual ammo and the targets. In general, Faster = more deformation on impact if you're hitting above the pressure driven shock threshold of the materials and are creating a shockwave. Otherwise, you are just measuring the plastic deformaability of casting and the material it's fired at and the drag through the target in the trans-sonic regime. In both cases you're going to see a classic hydrodynamic instability emerge that occurs whenever a high density wave impinges on a lower density boundary. This instability will cause turbulence and can overcome rifling as well as the aerodynamic stability that comes from having the center of mass behind the aerodynamic center of drag that can initiate tumbling. This is actually a really nice bit of physics that is accessible to most people who did ok in high school math. It shows up literally everywhere from virus particles traveling through an n95 mask to aeroplanes traveling near the speed of sound to sand and rocks moving downstream in rivers, and into the heart of nuclear explosions!

If you have a .308 rated barrel, you're going to find that 7.62 x 51 has trouble extracting. It has a thicker walled cartridge and lower pressure. You'd think the lower pressure would mean less expansion on the brass - and maybe it does - but it doesn't matter; the thicker wall will make extracting the brass a little tougher.

[@TheLibertyfarmer]

What to stock up on depends on what weapon system they'll be used in. 7.62x51 has tougher brass that can hold up better to battle rifles like the CETME, HK G3/91 family that are known to tear off rims of .308 cases due to their violent extraction/ejection. M1a/M14 owners should stock 7.62x51 as well as their gas systems are not adjustable and designed/tuned for 7.62x51 pressures. .308 can put a real beating on them. (Similar issue to the M1 Garand being designed for M2 ball pressures and can be damaged/worn out prematurely buy repeated use of much higher pressure commercial 30-06 ammo.)

Depends on what your using the round for. Range practice, 7.62, hunting, .308

[@mavericknonconformist69721]

Used to run Winchester brass, large RP, 175gr. BTHP, 4895 or 4064. Both mega accurate. Ran 168gr. BTHP for hunting.

I'm wondering if the one erratic shot hit a previously trapped projectile, and was deflected out the side. That's my best guess. Thanks so much for doing this one! I was really wanting to see them side by side, and I don't have a setup like you do to test them myself.

I’ve always been told you can’t shoot a 308 rd out of a military gun designed for 7.62 nato but you can shoot a 7.62 nato in a civilian gun designed for 308..

[@leroyjenkins4811]

You’re right, as .308 Win is a higher pressure round. However, read your owner’s manual. Many firearms can shoot both out of the same weapon.

[@markcole6475]

@@leroyjenkins4811 yes, that’s what I stated ..typically a rifle designed to use 308 caliber can use 7.62 rd.

[@SEPTEMBERMAN]

I have a Howa 308. Howa is totally against firing 7.62 through it. Kinda nutz

[@steffanwamsley7575]

7.62x51 chambers are slightly oversized, 308 is generally higher pressure (if I remember correctly), and cases are thinner, causing occasional case head separation.

I blew my neck disks out. The 30-06 hurt so bad, I thought hunting was done UNTIL I got S&W AR10 AWESOME I was back in the game. I use very very expensive ammo for hunting, for farting around I used mil surplus. I have 2 great scopes, both on quick detach scope mounts. For who is woundering, it kept the zero. Yes shocking. Great video.

[@ericstites9470]

Which would I stock up on? The cheaper one, with one caveat - has to be clean burning. If I recall correctly the 7.62 is loaded to 60Kpsi, while the .308 can go to 62Kpsi. I believe that's reflected in the data from your shot groups. And yes, that's some amazing spreads for factory ammo!

[@giantent763]

You have used a confusing unit abbreviation. K/k when in English units means kip, which is 1000 pounds. Saying 60ksi is a bit more clear. Not trying to be a jerk, just giving some knowledge.

[@ericstites9470]

@@giantent763 sorry to confuse - in the US 62K is simply an abbreviation for 62,000.

[@warrenharrison9490]

I chose an 18" Ballistic Advantage "optimized" barrel it handles both no issues.

Best sand segment ever.

[@josephsearls5142]

I would have liked to see tests on ballistic gel comparison to see wound channels and depth but also more time & detail of cell velocities.
