So, /k/. Age old question for today.

Which of the 2 calibers are more effective for home defense in their optimal builds? (.300 BLK in an 8 inch barrel and 5.56 in a 16-14.5 inch barrel?

Ballistics, Over penetration (or lack there of) and any other factors considered.

EIGHT? An 8-inch barrel!?

Why the fuck would you use such a short barrel? Do you want a rifle with no practical purpose beyond the length of your living room?
>>
>>34786396
the only .300 that counts is 300 Win Mag you fag
>>
>>34786408
8 inches is what .300 BLK is designed for you mongoloid. Its optimal for taking advantage of the quicker powder burn while still being reliable.

Get with the program.

Then my hunch was right that the .300Memeout is a shit round.
>>
Out meme them all with .458 socom
>>
>>34786451
How? it literally allows a rifle to be shorter while getting similiar ballistics as a 5.56 with a much shorter barrel length and similair reliability?

If that makes it a meme then you are a dumbass.

For HD.

Try again fudd

Might as well shoot a slug.

Terrible over penetration.

I don't think it's going to matter at HD ranges?

A quick glance at the reloading manual shows that subsonic .300 AAC 208 A-max, a very soft bullet, uses roughly half the powder of 62gr 5.56, so maybe that would be easier on your ear drums?

Holy shit, you're retarded.

.300 BLK gets a full powder burn in 9-inches of barrel, the difference between a 9-inch barrel and a 16-inch barrel is about 200 FPS (2300 FPS to 2100 FPS) with 110 grain bullets.

.300 BLK out of a 9-inch barrel has like 95% of the energy that a 5.56 round has out of a 16-inch barrel.

Use your damn head for like 2 seconds. You're better than that.

>>34787808
.300 BLACKED is basically Western 7.62x39
>>
it's inferior in every way to 7.62x39


7.62x30 AKA meme out was designed by some fat bubba literally,look him up, shit round for an already shit gun.
>>
>>34787867
> in every way
Come on now, anon. Half the reason for the caliber is subsonic loading.

It's hell finding even 150gr 7.62x39 these days. Point me at the +160gr .311 bullets. And no, I don't mean some silly .303 Enfield bullets that I'll have to seat stupidly short in a brass 7.62x39 case.
