Ammo tested by the military

I have these ammo boxes that my father. Got in the mid to late seventy . I was told that the army had tested this round as a replace ment for the .308 in machine guns . Can a

nyone confirm this?


This is about the only info I could come up with.


Living close to Fort Leonard Wood we saw some odd ball stuff . I always thought that it could have been loaded with full metal jackets for police or prison guard has use.


6.8 SPC is the evolution of this round. .30 Remington is currently defunct.


In 1906, Remington introduced their line of rimless rifle cartridges. These included the subject of this article, the .30 Remington.

The .30 Remington is obsolete today, but at one time (along with the .303 Savage) it was the principle challenger of the famous .30-30 Winchester. Oddly, it has recently been rediscovered as the parent case of the 6.8mm SPC cartridge. Factory loaded ammunition in .30 Rem. remained available in the 1980’s from both Remington and Winchester, and possibly into the 1990’s.

The .30 Remington is basically a rimless version of the .30-30. Its case capacity is virtually identical, and reloading data suitable for use in the .30-30 is also suitable for use in the .30 Rem.

The .30 Remington case is a rimless, bottleneck type 2.03" long. The rim diameter is .421" and the rim thickness .045". The overall cartridge length is 2.525". Bullet diameter is officially .307", but standard .308" bullets are used. Primer size is Large Rifle. The SAAMI maximum average pressure is 38,000 cup.

The .30 Remington is no longer included in most reloading manuals, but for those with a supply of brass, .30-30 Winchester loads may be substituted. This is specifically stated in the Speer Reloading Manual Number 13.

The 45th Edition of the Lyman Reloading Manual included data showing that the 150 grain Core-Lokt RN bullet (SD .226) could be driven to a MV of 2123 fps by 30.0 grains of IMR 3031 powder and a MV of 2364 fps by 33.0 grains of IMR 3031. The Core-Lokt HP 170 grain RN (SD .256) could be driven to a MV of 1893 fps by 27.0 grains of IMR 3031 powder, or to a MV of 2114 fps by 30.0 grains of IMR 3031. These Lyman loads used Remington brass, Remington 9 1/2 primers, and were test fired in the 22" barrel of a Remington Model 81 rifle.

It is perhaps worth noting that .30 Remington rifles with box magazines can safely use spitzer (pointed) bullets, although at .30 Rem. velocities there is not much advantage in so doing. For woods and brush hunting, for which the .30 Remington was designed, a flat point or round nose bullet is generally preferred.
