Gun Science Library
D.E. Watters replied to A_Mysterious_Stranger's topic in Ballistics Science Discussion
Back in 2009, I stumbled across a site hosting the annual command histories for the Commander in Chief Pacific (CINCPAC) from 1960 through the mid-'80s. I found an interesting tidbit in the 1974 history regarding an examination of establishing South Vietnamese production of the Lazy Dog munition for the VNAF.- 40 replies

Designing A Rifle From Scratch(ish)
D.E. Watters replied to Sturgeon's topic in Infantry Tools & Tactics
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. -

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. https://patents.google.com/patent/USD813974 http://appft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PG01&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.html&r=1&f=G&l=50&s1="20180156584".PGNR.&OS=DN/20180156584&RS=DN/20180156584 (Note that this application was filed once the patent Sturgeon listed was granted.)

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. http://sturgeonshouse.ipbhost.com/topic/104-documents-repository-small-arms/?page=3&tab=comments#comment-129310 Ichord Subcommittee Hearings Transcript https://hdl.handle.net/2027/uiug.30112109164266 Ichord Subcommittee Report https://hdl.handle.net/2027/umn.31951p00793094y

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

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.

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

Crane carbine vs midlength test results

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: https://ndia.dtic.mil/2018/armament/2018armament.html -

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.

SAR once wrote up a Class II Manufacturer that had converted a PSL from 7.62x54mmR to .50 Alaskan.

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.

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.

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. https://www.google.com/patents/US4066000 For that matter, I'd also like to get more information on the Springfield and AAI belt-fed machineguns chambered for SPIW cartridges. -

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.
