The Carbine as SBR

[Captain O]

It seems that those short-barreled rifles burn propellants inefficiently. People call this a "pistol cartridge" when it is obviously generates higher pressures than the .357 S&W Magnum (38,500 psi as opposed to 35,000 psi). The only handgun cartridge that exceeds the .30 Carbine is the 9 X 25 Winchester, and there's not much call for that cartridge in a "light rifle" is there?

So let's quit fooling ourselves by calling the .30 Carbine a pistol cartridge when it's genesis was from the .32 Winchester Self Loading Rifle Cartridge. The .30 Carbine always has been a rifle cartridge and will never be sufficiently efficient in shorter barrels. It is hard enough to gain performance from the Ruger's revolver barrel. (I shot a friend's Ruger in .30 Carbine and it was extremely loud and not efficient at all).

While it worked inside the tunnels for "short range shock effect" it wasn't much above ground.

Its time to face reality.

Had one along on my usual convoy down to Cam Rahn. It belonged to one of our chopper pilots and was a full auto capable weapon. I stopped on Hwy 1 about a mile or so before the rubber plantation and we all shot it. It might be a good weapon if you were locked in a car with someone. On full auto it was ridiculous. No cigar.

That's a good one...! Never heard that one before!

I have to disagree with part of this. I have a Ruger and the AMT automg in .30 carbine. My Ruger, though it is louder then a rifle and does have a huge flash, has been accurate. and reliable. The AMT is a bugger to get back on target, not as easy to shoot.

Loud is relative, the reason we wear hearing protection, the Ruger is nothing compared to others, try a S&W .460 or .500 if you want loud. These are loud.
