An intermediate cartridge is a military assault rifle cartridge that is less powerful than typical full power battle rifle cartridges such as the United Kingdom .303 British, Russian 7.62×54mmR, German 7.92×57mm Mauser or United States .30-06 Springfield, but still significantly more powerful than pistol cartridges.
The .30 cal has very similar stats to the .357 Mag (a pistol cartridge). I grew up shooting the M1 Carbine and Ruger Blackhawk in .30 Cal. It is not even close to the 5.45x39, 5.56, or 7.62x39.
The .357 was never a military round. It is quite powerful when fired from a single shot rifle of a model 92 lever action. I have had both and they are excellent in .357 mag.
The standard military rounds such as .45 auto, 9mm, 32 auto, .380 British revolver round, 30 Tokarev, 9mm Makarov are none even in the same ball park as the .30 Carbine.
The 8mm Kurz, the 5.56 and the AK round are in the same class as the .30 carbine.
“The .30 cal has very similar stats to the .357 Mag “
Try again, unless you mean 357 mag out of a rifle, or you mean that at 100 yards, the 30 carbine still packs more power than the hottest 357 magnum loads produce at the muzzle.
Also, the new belle of the ball is the 300 whisper. its non suppressed load is, wait for it.,,,,, a 125 grain 7.62 at 2150. A pointed, slightly warmer 30 carbine is the hottest spec op round to be had these days.
