AR's the wave of the future....................

[Mike_from_Texas]

Go the other way. Copper bullets are long for their weight and require faster twists than standard lead based bullets of the same weight.

Which reinforces what I said. Copper bullets are even longer to get their weight up.

Are AR's the wave or just a fad to be the cool or tacticool guy? Either way they'AR fun! I went against my better judgment and ordered a 7-08 AR10 barrel. Better judgment being not a fan of that caliber, let along the cartridge. A friend of mine has been shooting this cartridge for decades and it's his go-to kill all cartridge. With a 6.5prc AR10 barrel on order it'll be interesting getting it to shoot. IF it works out, then I'll be ordering more short mag AR barrels. I will be subjected to 2.830ish on length which isn't a big deal. What cartridges do some of you have that are not a normal chambering in AR's (10's or 15's).

Different caliber and cartridge, 338 Federal. Chambered and finished the barrel from a 1.25 blank straight. Sorry, not an AR10, but an M1A. AR10 barrel is much easier though, M14 barrels are PITA to spin up from a blank.

I have another blank to do a 338 Federal AR10 after I finish my 338 NM.

Will run it suppressed with a AAC Titan QD. Running the can on my 300WMs now, but it's a 338 can.

338 Federal is a thumper in the 308 Win pedigree

My first AR was also a Colt SP-1, purchased in the late 70s. I purchased that model because it most resembled the M-16 I used for two years in Vietnam 1968-1970.

As expensive as that model is today, I wish I would have kept that one. I have several other ARs, but all have the 'modern' look, not the 'retro' look of the SP-1.

Why hasn't been mentioned that ARs will soon go the way of the DoDo bird. Seems insane but the Dems will get it done like all else they have and are doing to this country.

Get what done? Is it time to go boating?

All my guns/etc. drowned many years ago.

you sound like a sore loser, I don't give a flying **** what politicians say about my gun rights, im keeping my guns. and gun rights as a whole have gotten better since the sunsetting of the AWB in 2004

this gif illustrates it perfectly. any more of this namby pamby oh woes me bullshit can suck a tailpipe.

It shows that length is the deciding factor. Not weight.

If you had four bullets. All 220 gr .30 caliber.

Bullet #1 is made of depleted uranium, flat based spitzer point.
Bullet #2 is made of traditional lead and copper, flat based spitzer point.
Bullet #3 is made of solid copper, boat tail with a high BC point
Bullet #4 is made of aluminum, flat base spitzer point.


Bullet #1 would work in a standard .300 Win Mag just fine.
Bullet #2 would work in a standard .300 Win Mag just fine.
Bullet #3 MIGHT work in standard 300 Win mag but would work a lot better with a faster twist.
Bullet #4 wouldn't stablize or work in a standard .300 Win Mag.

This is something that many older shooters and reloaders are having a problem with.

It used to be that if you went longer, it of course increased the weight, so everyone focused on the weight being what determines twist rate.

However now we have bullets made of non-traditional metals, bullets with very long ogives. It because apparent that LENGTH was what determines twist rate. That and velocity.

300 Blackout illustrates the last statement. To stabilize heavy/long bullets at subsonic velocities you need to have a faster twist rate. 8.6 Blackout shows it even more with standard twist rates of 1:3.

Nope.

What we are seeing in a few Blue states is the last and biggest temper tantrum of a bunch of leftists reacting to Bruen.

Saint Thomas of the Gun even warned them not to get even more stupid in Bruen. When this next batch of gun cases reaches SCOTUS I have a feeling that the decisions will be written in such a way that all wiggle room is going to be eliminated. SCOTUS setting absolute restrictions what are sensitive places, possibly nationwide Constitutional Carry or at a minimum forcing states to recognize out of state CHLs. Weapon bans taken off the table.

Is the ar the wave of the future I don’t think so I feel the future is now. It’s been a well proven an battle tested design for dang near a life time.

Shot my first M16-A2 in 02 while in basic training an I got hooked. Got my first AR in 05 it was a bushmaster and compared to what’s available now it would be entry level.

I’m down to one AR now it’s a home brew with the best parts I could afford an will never part with it.

Mailman brought up something important here. With load and bullet selection, how fast we send that bullet with what twist plays a big part in accuracy.

7.7 twist in a 24 inch barrel certainly helps the accuracy in my 6mm creedmoor.

MOST FACTORY MADE RIFLES HAVE A TWIST RATETHAT IS A COMPRIMISETO SHOOT MANY VARIOSLOADS THIS IS WHY WITH RELOADING YOU CAN OPTIMISEYOUR LOADS TO A SPECIFIC RIFLE! MOST TWIST RATESARE ACUALLY CASED ON THE LENGTH OF THE BEARING SURFACE OF THE BULLET NOT WEIGHTBUT AS GENERAL RULE HEAVIER BULLETS ARE TYPICALLY LONGER THAN LIGHTER BULLETS

 

[General Zod]

All i know is that everytime I go to the local gun store to look at ARs, I always see someting in blued steel with nice wood that i like a whole lot more.

So I suppose they are not the wave of the future for me.

Yeah, I know what ya mean...


LOL

That's why I have a Mini-14. I like walnut stocks.

 

[BeatTheTunaUp]

Wave of the future? Nah, there's already better 5.56 rifles. I own 3 non ar's and 2 of them are much nicer to shoot than any of my AR's. The AR just has a weird reverberating impulse in the buffer tube that I never noticed until shooting the Cetme L or Bren 2. Even with David Tubbs flat wire springs, they just feel gross now in comparison.

That being said, it's the king. There's not a better option that can be had for under $500. They're cheap, accurate, and most importantly work.

 

[TEXAS "All or nothing"]

Yea but they go hand in hand. Diameter is fixed. The only way to add weight is length. I suppose you could use an exotic material like tungsten but that comes cost prohibitive.

Have you not looked at the different lengths of boat-tail bullets of the same weight. FMJ's being the shortest of most bullets of the same weight. For longer bullets of the same weight are mostly target, the shorter is hunting and even shorter are fmj's. If you have ql, change between different brands and different style bullets of the same weight and caliber for just a comparison.

Show me where I’m wrong.

Take a .224 55 grain FMJ. It’s a flat base short bullet. Even a 55 grain target bullet is still short albeit with possibly a longer ogive section but that has no bearing on the rifling engagement.

Now take one of the 80-90 grain .224 bullets. They are going to be longer. There’s no way around that.

I do have QL but not following what you are saying to look at for comparison.

What exactly do you have AR's for? Long distance shooting? Otherwise I'm getting confused as to the ballistics argument in this thread.

Honestly just to plink with I don’t hunt anymore an sold off most of my rifles after that.
223/556 is cheap enough for a good range day and with a .22 conversion it’s even cheaper and more fun imho.
