It's a tiny round best suited to taking potshots at gook and haji children. I want something that will put big holes in things so they don't get up.
>>29437831
No Custer, we aren't fighting the Native Americans anymore. We've made peace.
>>29437593
5.45x39 is really fun in the AR 15 platform.
If you do go with it you will need a heavy trigger spring and enhanced fireing pin.Other wise your gonna have alot of light primer strikes.

your'e better off buillding 458 SOCOM than this
>>29438587
If you're getting into snowflake ammo you should be reloading anyways
>>29438620
that's what he's saying.
.458 bullets are far easier to come by than .50, since they're also used in .45-70, .458 winmag, etc.

Actually you can make an AR 15 fire .308 you just don't have a high enough power level.

.300 bleghout and add a suppressor to justify not just using 5.56.
>>29437593
Get a 6.5 Grendel, wolf has been making ammo for a while almost as cheap as 5.56 and if you want some fancier ammo it's not hard to come by. Probably my favorite thing I've run through an AR-15.
>>29437792
Seconded
>>29439266
This.
>>29437593
Fucking pussy, make it in 20/50.
That said, I've always liked the idea of an ar in .220 swift. I know its not on your list, but maybe think about that?
If you want a nice short rifle for general use, I'd say 300blk. It's a little expensive, but cheaper than .308 and getting gradually cheaper.
If you want something that does well at longer ranges, go 6.5 Grendel. Wolf makes ammo for reasonable prices, and there's some really good loads for long range shooting. If you're going for a full size rifle I'd go with 6.5
I'd go 308 because id then be able to use the same bullet to reload 7.62x39
>>29439607
>.308 ammo can be loaded with .311
Okay, correct me if I'm wrong, but I doubt that something called .308 is gonna be the extra .003" larger that a 7.62x39 round is.
>>29437593
.308 you fuggen retard, reach out and touch someone at 800 yards over and over again with a ~$900 rifle, its a no brainer
>>29437593
What is the rifle going to be for? You can't choose a caliber without knowing its purpose.
6.5 Grendel is a great intermediate cartridge; very accurate, recoil's not bad, you didn't need the last 5 rounds in your magazine anyway, and it has enough power for people to hunt with. I've only shot paper, but people do hunt with it; Alexander Arms even offers a gucci 6.5 AR in Cryptek highlander.
How does the supersonic .300 Blackout compare to the 7.62x39? Is it worse or the same?
>>29439837
This is getting a little into the technical side, but supersonic .300blk does better than x39 because of the ballistic coefficient and the abundance of really good loads. Its main advantage is that it works in your standard AR with nothing but a new barrel and gas tube.

>>29439725
fuck that weak shit. If you want to reach out and touch someone with an ar pattern rifle..... 6.5 Creedmoor for the win.
>>29438581
But with a fixed up front sight, fuck that dinged up shit
>>29437593
Build an AR-10. The only difference between it and an AR-15 is the caliber: 7.62 NATO vs the 5.56 NATO.
>>29440002
And weight
And it's non standardized
And ar15 doesn't mean it's 5.56
And ar10 doesn't mean it's 308
>>29437689
I love the round, but 6.5grendal is a tinkers round. Amazing if you get it run properly but it's a gamble even with the right mags. Same thing with 7.62x40
>>29439266
We call ours .358 gremlin here
>>29439952

>>29437792

>>29437877
But anon, you have nothing to shoot at with your AR besides paper and your recyclables.
>>29439513
Pretty sure you need to go one more to the right friendo
>>29437593
7.62x39 AR's usually suck, .300blk is for people that were unhappy paying less for their ammunition, or with it having a flat trajectory. If you need a snowflake caliber, I say .25-45 Sharps or 6.5 Grendel. Then you've got an interesting machine.
Better still, get an AR10 in .308. Simpler, more affordable than all the other options, hits the hardest.
>>29439648
u use a resizing die on the case. Aks are stable with up to 250 grain bullets.

I like the .308 ..Makes my Day .
>>29440492
I don't think you're understanding. .308 takes .308 diameter bullets. 7.62x39 takes .311 diameter bullets. They are non interchangeable, unless you feel like using undersized bullets in your 7.62x39
>>29437593

He probably doesn't want a light caliber in general. 5.45 ARs are much less versatile than 5.56 ARs.

too much wasted meat. I want to be able to eat at least 25% of what I shoot.
That said, if they built it for a reasonable price, you can bet your ass i would buy it.
>>29437593
5.56 for plinking
6.8spc for SBR/HD/hunting
6.5 grendel for hunting/long range
7.62x39 is for slavguns
7.62x40WT is expensive
25-40 sharps is neat
.277 wolverine is neat (6.8 pill in 5.56 brass)
6.5 mpc is neat
458 socom for thumping
300blk is gay
pretty sure 358 gremlin is still a wildcat, so good luck with that
>>29437593
.300 blk or that other 6.5 that's shorter than 6.5 grendel, unless you have the money to do an SBR in .458 socom with the loudest brake you can.
>>29444552
you probably mean 6.5mpc. its kind of a wildcat, SSK made it, but afaik didnt do anything besides patent it and make some barrels

You can squeezebore up to about 0.004" without significantly increasing chamber pressure. This is actually standard practice with cast bullets and common with plated bullets. Has a side effect of occasionally improving accuracy (though I doubt it will in this case, 99.99% of .311 bullets are junk)
Also you can run the bullets through a .308" sizing die to squeeze them down before loading.
>>29439880
It's also very marginally faster with similar weight bullets (about 50fps faster with 125gr bullets than x39 is with 123gr bullets), and does significantly better out of <10" barrels.
Recoils less too due to using about a third of the powder of x39.
>>29440081
>and it's nonstandardized
No longer true. The Armalite AR10 pattern is dead as fuck, even Armalite is now using the DPMS LR308 pattern.

>>29443336
I don't think you realize how wrong you are.
You can, and people do, safely shoot .311 bullets in .308 diameter calibers.
>>29437593
>ctrl+f "5.7"
>not choosing the most special snowflake round as alternate caliber
Just go for the AR57
>>29437593
If you don't build one in .338 Whisper Mk2 you're a disgrace.
>>29445052
>special snowflake
>requires no custom made parts or handloaded ammo, can buy a complete upper ready to go from 3 different companies
I don't think you know what that phrase actually means.

>>29438552
Too long, famiglia.
>>29440701
What did they do with the magwell?
>>29439513
That would be .50/20. You put the new caliber first, then the old caliber.
.700 Nitro Express
Can someone explain to me why I can find bonded bullets in boutique calibers like 300blk and 6.8 SPC for less money than I can find bonded 5.56?
A quick jump to ammoseek shows roughly $.60 per round compared to $.75 for 5.56. Based off of supply, shouldn't this be the other way around?
>>29447014
Manufacturers are still pumping out m193/m855 ammo a fast as they can to catch up with the previous ammo scare and to get ready for the coming election cycle.

>>29437593
I'd say just buy Colt's LE901 w/ the conversion kit. That way, you'll have a quality .308 AR and can buy a .223 upper when you're ready.
>>29437717
I want to make an ar pistol with this
>>29437717
Own one, it's like a light .45-70 with the same AR parts. Mine has a comp4 aimpoint zeroed at about 50 meters. It's comfy to have around.
>>29447297
A .50 beo SBR is the best role for this round. It's a pistol round so it does fine out of short barrels.
>>29447248
Because it was almost banned and has a mild steel construction, which means it's AP to idiots
