Duplex 7.62x51mm???
I was browsing thru a military field manual for the M14, and came across the section of ammo. It had something I've never seen before. Duplex .308 ammo... It says its designated by a green tip. Does anyone know if this ammo is still available?
If I'm wrong please correct me, I won't be offended.

Don't quote me on this, But "maybe" In Cheaper than dirt? I Think I had seen that round in the book "Know your M1 Grand" some times Cheper than Dirt catalog will come up with odd surplus stuff. If I see it in some of my books I will let ya know- 0 -
Lee, this is the old M198 7.62 NATO duplex ball and was developed for the SALVO program, an attempt to increase letality of the M14 on full auto fire. Since no one could hit ANYTHING with an M14 on full auto, this woould double your chances. There were two bullets in the case, the front bullet had a green tip and weighed 84 grs. and had a recess in its base where the nose of the rear bullet, which weighed a bit more, rested. The rear bullet had a 9 degree base angle to ensure dispersion. Both bullets were made os solid steel and were copper plated. Interestingly the velocity of the front bullet was 2750 fps while the rear bullet traveled at 2200 fps. Chamber pressure was about 2000 psi higher than standard ball ammo. SALVO died with the introduction of the M16 and this round is mostly forgoten today. I'm sure there must be quantities floating around, although I have not seen any in many years. But then I'm not looking!

Lee, this is purely a collector item at this point, bringing $15 - $40 a round depending on the type (there was an earlier one w/ red tip), condition, etc. If you find some in shooting quantity at shooting prices, you will be doing very well indeed.
Mark, the SALVO project was predicated on achieving multiple hits with a single shot, based on analysis of WW2 casualty data. The 7.62x51 & M14 were simply one of many cartridge / weapon systems for which multi projectile designs were developed. First in *this* series was '06, latest (not SALVO, but a continuation of the same idea) is 5.56, and multiple projectiles have been tried in virtually every US military cartridge going back to the .45-70. SALVO also included an enormous variety of experimental cartridge designs in .22 to .30 caliber.0 -
Those who say that you couldn't hit any thing with the M14 on full auto have never fired one. The M14E2 was just as accurate as the model 1918 Browning which it replaced. It has to be remembered that the squad automatic is designed to provide a "beaten zone" of fire rather then point to point accuracy. 0 -

I really don't think it had anything to do with the rifle, it was the shooter who couldn't hit anything. Just hold it over your head and squeeze the trigger. Just read any vietnam novel or biography, they all mention it. Spray and pray...

Thanks for the input, I wasn't aware of this. Looks like I'm gonna have to add another plaque for an extention of my bullet collection...
