AR twist ratios

This post in a post that should be viewed in the context of preparing for society to collapse.

When it comes to the AR15 there are a bunch of different outlooks on what grain bullet to shoot out of the AR and what twist rate your AR should have. If you wanted to maximize your AR's performance then sure, 1-8 with 77 grain ammo is probably the way to go. but its just not practical. If society had a deep dark spiral into chaos and anarchy then you will probably end up shooting 55 grain ammo. It is the cheapest to buy. It is sold in bulk. It is the most commonly stockpiled ammo in civilian hands. The second most commonly stockpiled ammo is 62grain. It is also the most common weight used by Government forces. If shit was a 11/10 on that crazy scale wouldn't you want to be able to exchange magazines with your buddy without having to worry about it

A 1-9 twist will stabilize both the 55gr and 62gr bullets. 1-8 and 1-7 is too tight for 55gr. Wouldn't you want to have a rifle that accurately fires the ammo you are most likely to shoot?

The military uses 1-7 twist because there is a requirement that the M16 has to be able to stabilize tracer ammo. Tracer ammo being so long it requires a twist rate of a very heavy bullet. I think it is a stupid rule as i never saw anyone shoot a tracer out of a M16 or M4 or even have some tracers loaded into there magazine.

Many people don't understand the actual information to understand basic shit like this. They just have a credit card and buy the really expensive AR. The military uses a 1-7 so thats what they want to buy. But it appears that many people have bought rifles that use a much too high twist rate and are very expensive. All that money would have been better used buying a rifle that is much cheaper with a 1-9 twist.

So should any AR that was bought with the downfall of western civilization in mind have a 1-9 twist?

TL;DR

>TL;DR
Not enough time to read but got enough time to post. Go fuck yourself.

just have two uppers

At ranges youll be "fighting" at in SHTF none of this even matters.
And at ranges for LARPing as a sniper in SHTF, youd actually want the 1:7 twist with heavy bullets.
So either way your argument is invalid, youre just trying to justify your purchase of shit 1:9 barrel on Jow Forums for affirmation.

I've had no issue with light projectiles out of my 1-7 twist AR. 26.9 grains of varget under a 50 grain vmax produced great groups. This group was from last spring using Lake City brass. I've since picked up some Lapua brass that I haven't loaded yet, so I'm hoping to get even tighter come spring.

I just see people with really nice ARs with 1-7 twist barrels shooting 55gr ammo. Then i shoot a tighter group than them and they can't seem to realize what is going on.

Well maybe i'm completely wrong then

I'm not saying twist rate plays no factor in precision, I'm just saying if you reload, you can generally work up a load that will work in just about anything you have.

This load is tuned for my gun and I doubt it would perform the same out of someone else's. When it comes to factory ammo, you're probably right about twist playing more of a factor, but as said, if you're shooting long range precision, you're probably going to lean toward a heavier bullet anyway, and in a SHTF type event, you're probably not going to be taking 600-800 yard shots. Realistically speaking, even the most bottom barrel 3-MOA shooting barrel would probably keep you alive especially at short range.

>i never saw anyone shoot a tracer out of a M16 or M4
You might not have seen it but your section commander more than likely traded a few for use as an emergency laser pointer.

Sick blog post

In much of the eastern US, places with dense woods, it is very rare you need long range accuracy. It is rare to find a place to even shoot 500+ meters. If SHTF people wouldn't walk in the middle of a large field surrounded by treelines all around. Fighting in the forest and in town/urban environments is much more important. A 1-9 with 55gr PMC will meet all accuracy needs while giving you the ability to keep the oppositions head down.

That's all fine and dandy, but my 1-8 barrel shoots 55gr into 2-3" groups anyways. That's with unmagnified dot. I consider this good enough for shtf purposes.

>1-8 and 1-7 is too tight for 55gr
No such thing. You can understabilitze, but you can't overstabilize.

No overstablization can effect accuracy. If it didn’t they why wouldn’t we make all rifles with a 1-7 twist? You mean to tell me that all these firearm manufacturers don’t have a clue what they are doing? Why have different twist rates if overstabilization isn’t an issue? Do you understand what you are saying? Or are you butthurt that you didn’t think about it and bought a 1-7 twist barrel?

Twist rates are only for ideal accuracy. Not required for accuracy. I'm fine with shooting 55gr out of a 1:7.
From memory, the PMC 55gr fmj out of my 1:7 is 1.5 MOA and is cheap range ammo (pretty good desu) while hornady TAP 75gr is 1.1 MOA. Handloads made the most accurate load a 68 bthp at half MOA.

>If it didn’t they why wouldn’t we make all rifles with a 1-7 twist?
Because retards buy 1/8 and 1/9 twist barrels thinking there getting something.

He's right user. Too fast of twist magnifies the imperfections on the bullet but doesn't guarantee an innacurate load or make it a tumbling unstable mess like too slow of a twist

It also keeps the centerline of the round parallel to initial point of aim. This in turn creates more drag at longer ranges

I guess I’m an idiot then

is there a graph for AR-10 twist rates and barrel length?

>1-8 is too tight for 55gr

Not optimal I guess would be more accurate

Look up 308 barrel twists dumbass.
1:10 is pretty standard for most

Stop being fucking autistic literally none of this matters just shoot 55gr out of the shortest barrel you have.

ITT: OP buys a $35 BCA barrel for SHTF and tries to justify his purchase, mainly to himself by shitposting.

Interesting thread idea OP

>in line with the thread idea, maintenance training/tips for the AR pattern rifle? Wet weather, cold temps etc.

So would any other twist rate

Ive been in TWO major hurricanes which is about as close to SHTF as I think I’ll ever be. One time I stayed. One time I left. The stores were empty, the streets were empty, the gas stations closed. Both times I had my 10.5 and both times I gave my sister a middy carbine. Evacuating we kept them in between the seat and the drivers doors in our cars. When we left we drove up into the Florida pan handle and separated. I went to OH she went to Texas. I never once worried about the bullet weight or the twist ratio AT ALL I knew if the guns had to be shot it would be in a rest area from 10ft away or inside the house from 10 ft away. OP and all the other preppies are faggot larppers. Real people have already been in and survived SHTF situations and the only advice you need is plan ahead, have plenty of water, carry cash, and FUCKING PRACTICE with whatever bangstick you want to use to save your life.

Lots of temperature resistant oil, I.e. ones that don't gum up when exposed to cold

Ive come to prefer Cherry Balm grease, they have a bunch of info on why grease is the best for open lubrication machines, which is basically what guns are.

You both are room temperature IQ nogunz larpers.
The AR should be run dry in the cold.

>he doesnt get weapons grease for winter conditions

Get a load of this retard.

>mechanical device with sliding surfaces should be used without lubricant for better performance
Pray tell wise one, why do you run your platform without lube? Why is a protective oil film bad in wet weather?

Sweet a picture of you in the desert with a milsurp gun. Now I’m positive that you are an expert on ARs in the winter.

ts. There is little risk of damage from friction, as the extreme temperatures will moderate heat within the firearm. Also, the amount of wear incurred by the lack of lubrication over shorter time spans is generally negligible, and easily managed by action smoothing by a qualified gunsmith. The important thing to remember here is that every trace of lubricant and the cleaner used to remove it must be completely gone before the weapon is exposed to the environment.

How does your AR run when youre larping at the range on a chilly day?

>shoots dumpster dog 2.5 years ago
>brags about it online still.

I have one beater AR I use for innasnow camping and it’s never seen lube.

Have an animal from this year atleast.

>is a faggot

Like pottery.

Just because your garbage rod AR can run lubeless doesnt mean it should, nor does that mean its the best way.

I prefer grease, and mine run perfectly on Cherry Balms winter stuff. Please kys.

How much do they pay you to post about Cherry Balmz Brand® Scented lubricant? Also I didn’t get BTFO. We’re talking about winter AR tips and some idiot posted two pictures of him hunting in the sandbox with Cindy Loo Who being the only one in the pic holding an AR. Just go anywhere and read. The syrup niggers and the Scandinavians all run dry. Just because Mr. $60 lube guys commercial told you one thing doesn’t mean it’s the truth. It’s trying to sell you a product and it’s working. Itsbnot damage control if you’re trying to stop the spread of misinformation
