Other than the cost of ammunition and having to use 6.8 magazines instead of 5.56 magazines, is there any benefit to using 5.56 over .224 Valkyrie at any range? I have to assume with a 6.5" twist barrel to stabilize the heavier 90 grain pills, Valkyrie would be a better terminal performer from every barrel length and at every range to go along with the much ballyhoo'd external ballistics it boasts. Is the lower magazine capacity the only other downside?

If the trend in 5.56 ARs over the last decade or so has been toward longer, heavier bullets for greater terminal effectiveness in shorter barrels, wouldn't a Valkyrie be better at that too?

I want 277 Wolverine to gain some traction. Supposedly close to 6.8 SPC in terms of performance with only a barrel change required. No special brass or mags, easily formed from .223 unlike the more difficult to form 300 BO.

From what I see on FNForums, a "6 bolt" receiver to barrel trunion mounting system, probably among other differences.

> if they put any work in hand-fitting and lapping the bolt to the barrel extension as you should on any precision rifle

I don't have anything to base this on, but I would not expect any hand fitting from a company like FN on a product like this. Probably tighter QC standards, but I don't think they'd pull out the Belgian gnomes for this one.

Versus the "4 bolt" mounting. This pic is from my 16, but the barrel on the 17 mounts up the same way.

And by the way, it does return to zero pretty well. Which I was slightly disappointed with since my aimpoint is cranked 3/4 the way to the right. That's right, it returns to zero, way off to one side.

(But then shoots great... so whatevs.)

I guess in that sense the SCAR's gas system sorta represents the twin turbo 4-cylinder of the Ford Focus RS wherein it squeezes as much out of its input as possible but is very highly engineered and necessarily high-precision. Whereas the system I'm most familiar with is direct impingement or other more crude, higher volume or vented piston systems which is basically like an LS1 that is basically old, crude technology at its most refined that you can basically tune to do whatever you want. But it's always going to be less efficient for its output than the new hotness.

But maybe that's a dumb comparison.

I was thinking about how video games often balance guns, and I got to thinking about the cartridges themselves. I found this, but it's too much damn information to digest.
https://en.wikipedia.org/wiki/Table_of_handgun_and_rifle_cartridges

I was thinking more generally. Are pistol cartridges slower than rifle cartridges? If so, are the bell curves between pistol/rifle dramatic, or is there a bit of overlap? Again, speaking generally, is it fair to say that pistols have shorter effective ranges than other weapons (low velocity, thus range)?

  This is an old US Army training video on ballistics that might help shed some light on powder burn rate, pressure curve, barrel length, etc. A lot of it isn't relevant to your question but it helps explain why cartridges on the "pistol" end of the spectrum use smaller volumes of faster burning powder and shorter barrels and and cartridges on the "rifle" end of the spectrum use larger volumes of slower burning powder and longer barrels.

If you're interested in old time .mil training videos, archive.org has them all available as high quality downloads. you don't need to stream them, you can make a big collection and stash them with your anime so you have something neat to watch if the internet dies. http://www.zenoswarbirdvideos.com has a lot of the old aircraft training films organized.

Federal judge blocks publication of 3-D printed gun blueprints


A federal judge on Monday blocked a Texas-based company from making digital blueprints for 3-D printed firearms publicly available online.

The decision effectively criminalizes publication of the 3-D designs for guns, banning Defense Distributed founder Cody Wilson from posting the digital files on the Internet. The legal controversy has sparked a national conversation about the implications of untraceable plastic guns and constitutional rights.

The decision, in favor of attorneys general from 19 states and the District of Columbia, stems from a lawsuit filed July 30 against the State Department, which had agreed to allow Defense Distributed to publish an arsenal of firearms blueprints online in a planned settlement.

The states argued that the release of 3-D printable designs threatened national security and abridged states’ ability to pass and police gun laws. On July 31, Judge Robert S. Lasnik of the U.S. District Court for the Western District of Washington, citing risks to public safety, granted the attorneys general’s request.

The legal battle over weapon-design files dates back to 2013, when Wilson manufactured the first printed handgun. Days after Wilson made the blueprints available online, the federal government demanded that he remove the files. Wilson did, then sued the State Department. In June, the federal government reversed course and entered into an agreement permitting Wilson to publish his firearm blueprints online. He intended to do so Aug. 1.

Hours before he planned to publish, Lasnik stopped him.

There was a website I used to shop run by a guy with a cheesy mustache. He sells one-offs of old stuff like 1903's and military surplus like Mausers and K31s and such. He has a separate section for C&R and even Antiques.

If you buy from him, he wants you to email your credit card info and he gives you the option to email bits of it from one address and bits from another address... Because SECURITY!

I can't for the life of me remember the site, and I'd really like to.

I'm a big fan of the SCAR 16. It's a great shooter and the only problems I've ever had with the gun were short stroking when I put the gas regulator on suppressed, and when I managed to jam a round in the chamber backwards while trying to admin unload the gun. (Rolled snake eyes, critical miss.)

A Gesissele Super SCAR trigger is a must and I recommend some kind of rail extension. (PWS or KDG)

But, in reality, I hardly shoot mine anymore after building an AR for competition with an adjustable gas block and lightweight recoiling parts. The SCAR is heavier and has a huge amount of reciprocating mass. It's like the gun just pushes you around. A muzzle brake doesn't help much, since the brake works immediately as you fire, then some milliseconds later the bolt hits the back of the receiver and you get a thump.

Another note about the SCAR, gen 2 pmags do not drop free and need to be modified just slightly to prevent the bolt stop from riding up. Gen 3 pmags work great.

However, if I needed a straight up combat gun to fight space aliens, the SCAR would be my go-to. But if the threat consists of robots, dinosaurs, or robot dinosaurs, I grab the HCAR.

The FN was nice.

Whereas, I like the SCAR, I'm more familiar with the AR/M4 platform.

And the X95 felt oddly natural, and nice and short.

OK 0p3r4t0r2zz, here's the thing.

Can anyone point me with a finger location of a fucking deactivated OR quality replica of either South African R1 rifle or Belgian FN FAL (or eventually other manufacture). I need to have it in "Rhodesian" scheme or be able to convert it into "Rhodesian" rifle for the display next year and so far I'll have better luck to fucking die than I do of a finding such rifle.
