Now make it in 6.5X55 Swede..

 

Hahaha!

 

(which no kidding, would be a fantastic idea, as 6.5X55 is absurdly underrated..An AR platform using 6,5 Swede would be amazing,)

A Czech company did just that, as well as a 7.5mm Swiss variant.  Google the Luvo Arms LA-11.

Just stumbled across this 1973-vintage document on DTIC:  "The Source Locator: A Directory of Information Sources in Small Arms Technology and Thesaurus." 

Just at the start I see a directory of all of the then current DOD personnel working on US small arms R&D, including a description of their areas of expertise.

Here is a direct link to William C. Davis, Jr.'s report on the modified T48:  “An Investigation of an Experimental Caliber .22 High Velocity Bullet for Rifles.”

SALVO I rifle field experiment

 

 

The T48 appears to have been chambered in what became .223 Remington.

No, that was the .22 Homologous, using a 7.62mm NATO case necked down for 0.224" projectiles.

FWIW:  There has been additional patent activity on the Federal 9mm EPR.

 The document you linked is Appendix 7 of the Ichord report, here's a not-so-great copy of the whole report. You can find better versions of all the appendices, and the report itself if I recall, on DTIC.

@D.E. Watters

FWIW:  The former document was part of the 12 volume report assembled by the US Army in response to the Ichord Subcommittee's report.  I linked all 12 volumes here.

That's a good point.  The only issue with a semi-rim is that it necessitates the use of a new bolt face for the AGL variant.

 

Maybe it would have made more sense to use 23x152mmB ammunition as the starting point.

It is conceivable that both the rimless and semi-rimmed cartridges could work with a breechface sized for the semi-rim.

If it is semi-rimmed but the others are not, how does it fit into the common link?

Perhaps that's why they made a new common link, instead of using the legacy KPV link?  You are either going to use a semi-rim or belt on a cartridge like that.  I wouldn't trust the rotating band for headspacing.

FWIW:  The US played with its Cal .60 case by necking it down to 12.7mm and all the way up to 27mm before deciding upon the 20x102mm.

I am probably re-stating the obvious here, but this looks like an attempt to make an all-in-one heavy machine gun/light autocannon/grenade launcher.

 

The round on the left looks like a dummy 14.5x114mm, the round in the middle looks like the same case, but necked down to 12.7mm, and the case on the right is a mock-up of a grenade cartridge.  All three cases have the same rim and body dimensions, so they can all use the same links.  I don't recognize the links, they don't look like links for a 23mm cannon or for a 14.5mm HMG.

The fat boi cartridge case looks to be semi-rimmed.  I'm guessing that it is in the 25mm range.

How many barrels total were tested?  Barrels of the same caliber and length will often show consistent muzzle velocity differences of tens of feet per second for no apparent reason.

Don't know.  The 2018 presentations haven't been posted on DTIC's webpage yet.

When they go up, it will probably be at this link:

And the best movie marketing scheme of 2018 goes to "Revenge"

 

Also, how does a 98 pound woman with zero body fat beat the shit out of three guys after being shot and - I think - impaled on a tree after a terrible fall and left to die without food and water in the heat of the Arizona summer?

 

My immediate guess is the supernatural, like "The Crow" and several other supernatural revenge flicks.

I honestly cannot believe this is even real. OF ALL THE DAMNED IP'S TO ADAPT TO FILM!?

 

If they don't bash up a moon base I'm rioting.

I'm anxiously awaiting the Q-Bert and Frogger movies.

Loved the Rampage arcades games though...

Nothing is more telling than looking at a tablefull of AR18's and AR180's, and noting the differences.

 

Buy an (original) Armalite for collecting, a Howa for shooting, and a Sterling for parts..

I caught a 1971 International Defense Review on eBay the other week.  It confirmed the Lockheed connection for International sales.  They would also supply the tooling and setup, while ArmaLite would handle QC.  Another interesting comment was that Mauser was looking at buying a license for it.

It even has the Bible verse marking intact.  John 8:12 really makes more sense for an NVD or WML anyway.

I'm guessing the SAS has a bit more freedom in their procurement (like most special forces units seem to).

The story at the time was that the SAS spent more money in testing the candidate weapons than they did in purchasing the selected L119A1.

Knox blew up a lot of test barrels with their ammo, from what I hear.

 

Someone still needs to interview Knox's George Reynolds before he gets too old and begins pining for the fjords.

I want to know about his 30mm single-shot and semi-auto underbarrel grenade launcher designs for the US Army back in the 1970s.  I believe that he was also behind Knox's  standalone semi-auto 30mm grenade launcher that was flogged for several years by Honeywell and then ATK before the OICW program finally drove a stake through its heart.  Most folks know him now for the current Armalite AR30 and AR50 rifles.

For Sale: Rare "Paul Jaeger" Customized Mauser

$ 2,075

 

Let's start with the pictures. This is a "custom" 7mm mauser. I don't know this Paul guy, but he looks like he knows what he's doing with a dremel and a blueing tank. Good for him.

FWIW: Paul Jaeger has something of a cult following among custom rifle collectors.

Might as well drive this home, too:
 

 

Never mind that the British SAS had acquired 5,000 AR-15 in 1965, and put them to use almost immediately in Borneo.  Never mind that they ordered another 13,000, circa 1967.

I still want to see the unsolicited Brunswick SAW.

For that matter, I'd also like to get more information on the Springfield and AAI belt-fed machineguns chambered for SPIW cartridges.

Bunch of G11 docs at the SAR archive (gotta search "G11" sadly).

The ACR trials final summary is also there.  It describes all of the candidates, even those that didn't make it to the trials.  Mind you, there are two copies; one is a crappy photocopy, while the other looks like it was scanned from an original.  I think this is the correct one.
