My 16” barrel is a 1:7, meaning it will stabilize heavier bullets better.

1:7 is better for heavier bullets in general? The higher twist rate is for lighter weight?

higher twist rates are better for heavier bullets. 1:7 is really kinda iffy with 55gr bullets but works fine with 62. 1:8 twist works well with just about anything you throw in an AR though

really the only reason not to have a 1:8 twist barrel is if you're using some crazy heavy ammo, like higher than 77gr

I have a 1:7 I'm but I'm running 62, havent shot it yet tho so we'll see

I thought 1:7 was the happy medium. Or was that 1:8?

1:8 is the happy medium

Guess I gotta run some chonk rounds lol

> @[VA] JediComms My favorite from vortex is easily the spitfire 3x prism. Clean, reliable, accurate, and easy to zero.
@Soulraiser I've been running a StrikeFire II on my 556 for a few years and haven't regretted that purchase.

Any tips for painting a rifle? Multicam style
Paint recommendation?

You should be running heavier rounds for defense anyway. Stuff like Hornady 75gr open tip match / boat tail hollow point. Its fragmentation is absolutely devastating

Hmmm Well, I may be mistaken indeed then. I'm still going to stick with my 1/7 QPQ aero barrel tho'

I run gold dots for defensive purposes, and 262 equivalent for offensive purposes

What do those decimals represent? MOA?

No they’re twist speed. Which literally none of use need to worry about unless you’re actually shooting well past 1000

Cali had another freedom week and stocked up on greentips

@Crye_Salesman No I mean where the rows meet. 1.8 2.8 etc. It says ideal is 1.5-2.0

green tip is pretty trash, though it's still about the cheapest barrier blind ammo you can get your hands on

tldr, all penetration, no fragmentation

Is green tip supposed to be AP?

nope

It's supposed to penetrate soft materials such as flesh and drywall slightly better than regular 55gr rounds

it will not penetrate any armor that regular 55gr won't too

Ah, ok.

HMMMMNNNNNN @Bogs_Bunny I don’t actually know?

Actually that couldn't be MOA. Cause under 1.0 is "bad"

Yeah green tip isn’t ap. Even M855A1 isn’t *actually* AP in the traditional sense, but it should penetrate M193 rated armor

That’s also just not how MOA works

by giving it a steel tip, they made it penetrate through body tissue better to more reliably meet penetration requirements and punch through stuff like car windows. However, by doing that, it naturally keeps it from fragmenting as well, but fragmentation is where 5.56 gets the majority of its lethality. Stuff like 75gr rounds fragment like crazy, doing a devastating amount of damage when they hit.

So it’s more lethal?

I’m assuming there’s more math there, and that number is a representation of a quantitative measurement of round stability

More lethal is a very relative term

With increased penetration that would decrease the chances of getting “stuck” and hitting vital organs, no?

Wasn't 556 an incapacitating round? Or is that a myth?

I’m legit just guessing so please tell me if I’m wrong

That’s extraordinary levels of fuddlore @Bogs_Bunny

also the numbers on the picture are the stability factor, which is determined by some formula

@Abe Clark yeah. If it has an exit wound it's not dealing all of its kinetic energy

Kinetic energy is pretty much irrelevant to lethality #

Well at least I'm learning. Lol.
