is 6.5 grendel worth it?
>>29074483
And there's the combo breaker. I would like to know this as well. It seems like a fucking cool round.
i heard a rumor years ago that it was good out to 800m and had close to the same knock down power as a .308
so, naturally i've been curious as i have a stripped upper and lower ready for build.
>>29073610
6.5 what? 6.5mm PDW rounds?
6.5 Grendel is like the perfect round with the best of 7.62x39 and 7.62x51 and 5.56x45.
Why has it not been accepted into common use.
>>29074082
9.7 mm
From what I heard was:
The company that devolved it guarded the patent for it like fort Knox and generally being greedy jews about it until about a year or two when the patent finally expired.
Now, companies are finally producing it. Apparently it's very popular in russia? I know wolf is producing ammo now.
>>29073610
It's not 6.2mm
>>29074676
Because America and Germany wouldn't budge in the 80s when Britain tried to push for a better intermediate cartridge and they went NUH UH WE GOT DA 5.56mm YO.
and then 30 years later, everyone is bitching about 5.56mm when we could have been using 6.5 Grendel in the 80s.
>>29074676
Money.
>>29074483
Yes.
>>29074676
Fudds and Noreen.
>>29074737
7.62x39 is the parent case of course wolf is making it.
>>29074483
6.5gren as a target or hunting round yes.
As a combat round (in an AR) not really.
>fragile bolt due to very large case head making its walls too thin (to be fair this also plagues the x39 AR's as they share a case head diameter and parent case, and to a lesser extent the 6.8SPC)
>mediocre muzzle velocity from a 20", abysmal MV from a 14.5" barrel
>Hague/Geneva-approved bullets won't fragment at its muzzle velocity, much less at 100-300m, it is 100% reliant on expanding bullets for lethality
>significantly more recoil than 5.56, would not work well in a SAW
>requires relatively slow-burning powder, throws huge fireballs from barrels shorter than 18", nobody makes a flash hider that even comes close to hiding its flash
>>29074573
It remains supersonic to over 1000m, but wind drift makes shooting beyond 800m a challenge. It's a damn good target round.
6.5MPC, which uses .223rem as a parent case, gets higher velocities with 107SMK's than 6.5gren does with 123 Amax's from the same length barrel while using the same bolt and mags. It also works well out of short barrels and recoils less. Unfortunately the only company doing barrels in it is low-volume. They're the same guys that do the Whisper family of guns.
>>29074213
My negro...
>>29075255
Huh...interesting.
>>29075255
>fragile bolt
how old is your info? afaik, the majority of the bolt issues were solved once SAAMI accepted it and it became wider knowledge that the x39 and 6.5G CANNOT share bolts due to differences in rim dimensions, they are functionally close, but not optimal. similar to 308 out of weaker 7.62 nato chamber or 556 out of weaker 223 chamber
as for 6.5 mpc thats bretty cool, if true
>>29074737
You're close.
It was developed by Alexander Arms, not that many years ago. The patent is still valid. What happened is:
>Alexander Arms designs new wundercaliber in conjunction with Hornady
>being the greedy jew he is, Bill Alexander wants ridiculous royalties and personal oversight of ALL products even sorta related to 6.5Gren
>nobody fucking buys it because it costs more than .308 as AA is the only one making it since no other company wants to put up with his shit
>it's not making money
>only companies producing it are Wolf, which is both shitty out-of-spec ammo and not paying royalties because they're Russian and can get away with that; and Hornady, which co-developed it and have partial rights to the patent so don't pay licensing fees
>Les Baer invents .264LBC, which is compatible with 6.5gren ammunition and is actually a superior chamber design
>AA is now actively losing money
>Bill Alexander goes "Fuck it I give up" and slashes his licensing fees and completely tosses any hope of oversight
>Wolf introduces brass-cased Wolf Gold, which is almost in spec (still uses large primers though), PPU licenses it and produces some
>begins getting popular now that ammo isn't $1.20 a round
>>29075351
>The 6.5 MPC (Multi Purpose Cartridge) is a SSK development urged by Brian Hormberg (USMC) based on the 5.56 cartridge shortened and opened to 6.5 MM and the same OAL as the 5.56. In the M-16-AR-15 rifles it utilizes the 5.56 bolt and magazines as well as all other parts except the barrel itself. Its design adapts it to a short Close Quarter Battle rifle with a 12” barrel moving a 107 6.5 SMK at 2400 FPS with superior full auto controllability and excellent accuracy. The 12” barrel model easily puts it into the realistic 300+ yard combat category and longer barrels stretch that realistic combat range considerably further. Factory ammunition is not yet available for the 6.5 MPC; however we are working on that. Ready to load brass and dies are in stock. The 120 grain BT is near maximum bullet weight for good performance. 85 grain is about the least weight for good performance. Some 140 grain bullets may be used but ballistically are counterproductive.

I thought it was AA. Wasn't 100% though. And yeah, he's a big time fucking jew. Didn't they do the .50 beowolf? A buddy of mine really wants one but Jew AA, so he's been looking at 458 soon instead
>>29075446
yeah AA did the .50beo.
Definitely steer him towards the .458 SOCOM. it's an all-around better caliber.
>more energy with less recoil
>not limited to the 3 companies that make .50AE bullets for reloading (it uses a .500" diameter bullet instead of the .510" diameter .50cal rifle bullet)
>can do everything from 250gr screamers to 700+gr heavy subsonics
Only downsides are it's necked and as such not as simple to reload, and brass is expensive (though still cheaper than .50beo brass usually).
>>29075473
Yeah, that's what he's running into for CONS on picking one up.
I saw a rem700 chambered in it once. It was pretty cool. 458 soon does have a pretty good following in Indiana too. We can't use regular rifle cartridges because "it might go through the trees and hit a house" according to the politicians. Or some such bullshit
>>29075473
I should also mention that .450 bushmaster is a great caliber as well.
However in an AR nobody's figured out a reliable mag for it yet. It's too skinny for a straight-up single stack in an unmodified AR mag like .458 and .50beo, and too fat to do a true doublestack. You end up spending more time tweaking feed lips than you do shooting it. Until someone starts making GOOD aftermarket mags for it, It's on the avoid list.
>>29075522
>boltgun in .458
That would be fucking sweet.
>"it might go through the trees and hit a house"
Same deal with IL, and they're actually worried about other hunters (or at least the DNR guys who did that piece of legislature were, dunno about actual politicians, they weren't involved). Too flat, and too high a hunter density.
>>29074483
It's co-designed by finns so of course it's good.
How does 6.5 Grendel compare to 8 Kurtz. It seems like 8 Kurtz would have been the go to round for Germany if nato didn't step in.
>>29075711
Well, it has more energy both at the muzzle and at range since it's got a significantly higher powder capacity while shooting a generally lighter and significantly higher-BC bullet at a significantly higher MV. However it also probably recoils more, and has a significantly longer COAL.
>8mm Kurz
123-150gr bullet @1920- 2250fps
>6.5gren
90-123gr bullet @ 2650-2900fps
