No they're fun to shoot!

Quieter at US ARMS matches.

That's about it though.

Much better bullets available for the 300, otherwise the ballistics are so similar it doesn't matter. The bullet selection is a big deal though, don't overlook that.

If you're putting it in an AR15, the 300 is far easier and uses all common parts.

one wonders why anyone buys those CZ Scorpions or the Sig mpx guns other than "fun".

People buy all kinds of stupid stuff thinking they are more than toys.

I recall we had an interesting discussion on these things under the handgun forum we decided that 9mm was big enough for grizzly bear with the right bullets. Form my HD gun is a Colt 6720 with an aimpoint T1 and TLR1 HL loaded with 62 grain federal fusions these discussions are "academic in nature" in an attempt to learn more about different cartridges and their applications.

That's a straw man argument. The two uses are completely different. No one is recommending a 300BO for a carry pistol. Once carbines came along that we're reliable and the same size as SMG's, SMG's were obsolete.

If your'e going carry a carbine, carry a carbine.

The carbine is a compromise, I'd take a 45 acp sub for close range such as home defense. As a 45 speeds up, so does effectiveness.

I never would consider the house as the same as combat... I'd assume... yeah I used the word, that a shot or two and generally the incident is stalled. I would not have to expect to communicate after shooting or during, there is only one other person in our house.

But that doesn't mean that after I"m finished with the 300/221 AR upper that I started 3 years ago, I won't have it sitting by the bed with the can on.

Not sure I'd have time to put on muffs and turn them on. Though the cur generally doesn't sleep through much...

I have fired both handguns and long guns in buildings. I don't envy that. It may be part of why I need hearing aids I think the dr said on the last visit, it was hard to understand him....

Point was though if I deem it needed to kill someone in my home, thats serious enough that I"ll take the hearing loss if it comes with it.

Obviously like anything else if I can avoid the noise or shooting someone I will do my best.

Having to shoot someone is beyond the very last thign on my list that I"d ever want to have to do.

a 9mm even "out of doors" is painful. I don't find the 45ACP quite as painful used in an emergency. I have killed several deer with a 223/6.8SPC 16 inch barrel without ear pro and cannot recall it was painful.

noticed the same thing. or better still, a pistol caliber pistol

....he said as if no one ever died from the effects of being shot with an Uzi, MP5 or Mac10 or Schmisser MP40 or Suomi KP-31 or PPSH41 or.... .

Please regale us with your vast experience carrying and using an uzi, MP5, mac 10, MP40, KP-31, PPSH41? As well talk about your experiences carrying and using M4 based SBR's in 5.56 and 300BO? Maybe you can illuminate the differences, pros and cons between them in regards shoot-ability, recoil, manipulations, range, etc, etc?


Then frost it with your findings in tissue damage, penetration, accuracy, etc.






I mean one might wonder why literally no legitimate organization/unit uses SMG's anymore for CQB....... Or at all.

Maybe you should do the same and list your experience.

Had to go full retard, didn't ya?

well, you certainly told me

pretty much

sounds like he stayed at a Holiday Inn Express once

are you the teapot or the kettle in this instance ?

FWIW, I already decided to go with an AR style SBR in 300BLK for this single purpose weapon. That's why I framed my original question as I did. All I was really looking for was advise on setting up such a rifle with regard to the gas system to "tune" it for the best balance of recoil, muzzle jump, ejection site gas, and cycling reliability. Within that framework, I do appreciate the advice on the supers vs subs, because it does impact the noise and would impact the gas system. It's hilarious how guaranteed it is to start with such a non assuming thread and it ends up in a death match. That's the way of the Campfire though

Are you wanting advice on how to tune it, or what parts to use, or ??
Are you handloading or buying factory ammo?
