The Carbine as SBR

One of my favorites!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Capt O, I respect your opinion and defend your right to have them. But for me, the idea of taking a .30 caliber carbine round within 100 yards from a 10" barrel or an 18" is "same same" for me. Yes, the round was designed for rifles. My next quest is to see if I can turn it into a true "pistol" caliber with judicious choice of a pistol powder. This will at least reduce the muzzle flash.

Plus, this is America! Who said we shouldn't have fun with our guns? Hell, I like things that go BOOM and this little shooter definitely goes BOOM inside of a closed structure! I love the feel of shocks waves in the morning! Of course, only on the exterior portion of my body, nothing internally. :-) I do not think I would ask your opinion of the 7.62x51 SBR HK clones that so many seem to love. I don't get it, but I hold no grudge for the man that wants that sort of affair. All flash and bang! Sure the ballistics are dismal, but somebody is having fun. And again, I ain't calling that little monster ineffective if I am standing within 100 yards of it. It would surely kill me deader than anything else.

Would the .300 Blackout be a more efficient cartridge in the format? Sure, from what I understand about it's ballistics. But for me, also this is about generating some historical references. Like my XM177E1. Yep, the 5.56 was designed for that 18-20" barrel, but same observation, I don't want one passing through me if I am within 100 yards of the dispenser.

For me, these items just have an appeal from a historical sense. They may be crap guns to you, but for me, there are ephemeral notes from my youth.

No offense taken nor intended. Attempting to make the .30 Carbine perform as if it's a self-loading pistol cartridge has been attempted in short barreled versions of the M1 Carbine. Sadly, none have been successful. Why? The cartridge requires a certain barrel length to perform within certain power parameters. The faster propellants don't seem to work well within the constraints of the Carbine's action.

I am not trying to "rain on your parade" but I don't want you to embark on a quixotic quest. I have "been there" and have "done that". I just don't want you to embark on a "fools errand".

Try 13 grains of IMR 4227 with a 115 grain bullet. Another shooter had used this to cycle the action. I never did get any velocities from this gentleman, but he said that it worked the action of his Iver Johnson Enforcer.

This is all that I know.

Something similar to this configuration of suppressed and then shortened barrel would be interesting.

Something similar to this configuration

That would be lots of fun, actually.

Yes, in .300 AAC vis a vis .300 Black out.

Thank you for this. I will definitely look at starting there. Need to get my bench back up and running. It was packed up for a move!

If a .22 can kill you (and it definitely can) a 30 carbine can REALLY kill you. People who have been to war never doubt that anything can kill you. A bullet pokes a hole in you, if it is in the head,throat or heart, you are dead, anything else you bleed. If the bleeding is bad and can't be stopped you're dead. It's simple and brutal. A 30 carbine with 5 gr of Bullseye can poke a hole in you.

Sorry, people. I'm not sacrificing power for "flash and bang". I'm trying to maximize my Carbine's efficiency, not minimize it. I want a 5.4 pound close quarter fighting implement, with as much effective power that I can safely wring from it (without battering the action to pieces, of course). Had I been a "tunnel rat" or someone confined spaces, such as a vehicle or helicopter, it would be an entirely different matter.

I want the ability to inflict as much damage against an aggressor as I possibly can. The .30 Carbine is an excellent "house gun" and is a prime candidate for suppressing neighborhood fighting or household intruders. With 5 30-round magazines, it shoud serve well in just such an emergency.

I really don't see the need for an SBR. $200.00 and a 9-12 month wait seem a steep price for a tool of such limited applications.

Is there a practical point to such an exercise?

It is my opinion that folks want the short barrel version for a "FUN" gun .
I have a SA TSMG for a "FUN" gun. For home defense it is to big and clumsy, but everyone likes to shoot it.
Some like the M2 version for a "FUN" gun, I have shot them also and they are fun, but FA in a house or yard is nuts.
If you are 'thinking about shooting people [self defense] Most people have 'their' preferred weapon. Use what 'you' are comfortable with.

Well, if I remember correctly after several years ago when I checked, a folded M1A1 with standard 18" barrel is shorter than an AR with a 12" barrel. And the Carbine can be shortened another 1-3/4" legally.
