The Firearm Blog

Good news. I will be back at the blog tomorrow.

I have so much work I am pretty much going to be working, eating, sleeping and nothing else until Tuesday.

I also doubt I will be able to make any progress through my 100+ email backlog.

Reader WarWolf emailed me this photo. It looks like it is a 5.56mm NATO round loaded with a semi wadcutter shaped lead bullet. weird. Can anyone identify the round and/or read the writing?

Would the ridge not cause chambering problems? Maybe the intended use is in a single shot rifle or pistol.

UPDATE: Mystery solved. Koko’s comment below:

This is a plastic bullet that was devised to provide the IDF with a bullet enableing a non-lethal way to stop Palestinian demonstrators during the first Intifada (1988-1993).

The bullet was to be fired at demonstrator legs – but ended up inflicting more drastic wounds then initialy imagened – even killing on accution.

The ballistics of the bullet proved to be strange – after a while the standing orders were changed to the ammunition to be used only by a trained designated shooter from a fixed ground position – then the bullet was dropped altogether and is not used today (as far the I know).

The load was also reduced – as noted on the package – this forced to shooter to manualy load the bullet after each shoot.

Makes sense that it needed to be loaded single shot!

Thanks to everyone for the translations and comments.

In the past tungsten has been considered non-toxic and more environmentally friendly than lead at shooting ranges. Recent research has shown that Tungsten is in fact toxic and potentially carcinogenic. Danger Room reports:

There have been growing concerns about tungsten for some years. An October 2008 Issues Paper from the state and federal waste managers’ group says that the “original position of the scientific community with regard to fate and transport, analytical testing and toxicology” of tungsten has “drastically changed.”

The report further warns: “Over the past years, soil and groundwater samples collected at certain small arms ranges have demonstrated that tungsten is very mobile and soluble once it is released into the environment. In addition, limited yet important health studies have also revealed that tungsten may pose risks to humans and ecological receptors.”

The Army has now stopped production of “green” tungsten ammunition:

The Army is concerned enough about possible risks that it has stopped making the tungsten ammo. “The U.S. Army developed a lead-free 5.56mm round during the mid 1990s with a tungsten-nylon alternate slug materiel. Environmental studies later determined that the tungsten-nylon combo had a possible environmental impact. The Army stopped production of its tungsten-nylon 5.56mm [rounds],” Tonya Townsell, a spokesperson for the Army’s Armament Research, Development and Engineering Center, tells Danger Room. “The residual inventory of 5.56mm Tungsten-Nylon rounds is still available for use in training at lead-restricted sites as it is deemed safer than lead.”

While the majority of lead-free civilian tactical and hunting bullets are either solid copper or copper jacketed with a tin core, some bullets do use tungsten. Two examples are Barnes MRX Bullets and Extreme Shock Ammunition.

The core of Barnes’s premium long range hunting MRX bullet is made from a tungsten based compound called Silvex. One the Barnes website the compound is said to be “non-toxic”:

The core of Extreme Shock frangible ammunition is made from a tungsten powder/flake compound called Ny-Trilium. It is also said to be non-toxic:

I imagine some people are not going to be happy after paying a premium for ammunition that promised to be non-toxic, only to find it isn’t. Is this lawsuit material? I don’t know, but I do wonder how long it will take manufactures of tungsten bullets to remove the “non-toxic” text from their websites.

Next month the 9mm Glock 17 will be available with the RTF2 (Rough Textured Frame version #2) frame. The RTF2 frame is often called the “4th Generation” frame.

Glock 17 RTF2

Earlier this year at SHOT Show Glock introduced the RTF2 variant of the Glock 22. From the press release:

The G22 RTF2 has been received with excellent reviews and is one of the top 10 sellers for FY 2010. In addition to the G22 RTF2, GLOCK, Inc. is proud to announce that on May 1, 2009, they will offer the 9×19 G17 RTF2 pistol, as they continue their pursuit to expand their RTF2 series. The G17 RTF2 is the second pistol that GLOCK, Inc. has released with the new rough textured frame and slide serration pattern. The newly designed frame incorporates more than 4,000 raised pyramids on the front, rear and sides of the polymer receiver and has a newly designed crescent shaped serration pattern located at the rear of the slide.

Recently, the Escambia County Sheriff’s Office was the first local agency in the United States to convert to the G22 RTF2, while at the same time the Louisiana State Police and Louisiana Department of Public Safety purchased 1300 G22 RTF2 and G17 RTF2 pistols, which has made them the first state agency to convert to both RTF2 series of GLOCK pistols.

The Kahr PM4544 is a new all black version of the two-tone colored .45 ACP Kahr PM4543.

PM4544N

The new all black PM4544 features a black polymer frame, just like its PM4543 match, but offers a matte blackened stainless slide to add to the overall “black-out” effect of the gun. The PM4544 matte stainless slide is blackened using an ultra hard and super thin coating. This coating has been used successfully in the knife industry to protect blades from corrosion and scratches.

Just like its counterpart, the PM4544 has an overall length of 5.67,” height of 4.49,” and a 3.14″ polygonal rifled barrel. The weight of the new all black .45 ACP is 17.3 oz without the magazine. The magazine capacity is 5+1 in a single stack configuration. The PM4544 also matches the PM4543 with drift adjustable, white bar-dot combat sights.

The PM4544 has an MSRP of $903 and the PM4544N night sight variant has a MSRP of $1,022.

WrenTech Industries have started selling a shotgun and Ruger 10/22 rifle variant of their Advantage Tactical Sight. The new sights work the same as the pistol version. To aim you simply line up the rear sight with front sight to create a triangular shape. This apparently allows very quick sight acquisition.

The Universal Shotgun sight fits any non-ribbed 12 gauge barrel that is 14″ – 20″ long and of .840” to .890” in diameter, which includes most non-ribbed Mossberg and Remington barrels.

Mossberg 500 Shotgun

The Ruger 10/22 variant is only compatible with the aftermarket Tactical Solutions fluted .22 LR barrel. It is designed specifically for .22 steel matches.

Both sights can be purchased online and cost $129.95. You can read more about the pistol sight system in an article [PDF Link] from this months GUNS Magazine.

The Rock Island Auction Company are holding a massive auction next week (April 25, 26 & 27). Thousands of guns are being auctioned from some prestigious collections. All the guns can be viewed online and it makes for interesting reading.

Here are a few interesting firearms I came across:

German WW I Mauser Model 1918 Tankgewehr 18 Anti-Tank Rifle

This is a nice example of a rare and desirable German massive, single shot, bolt action, 13 mm anti-tank rifle. Known as “Elefant-Buechse” (elephant rifle) by the German Army. The Tankgewehr 18 (T-Gewehr) was an up-scaled, single-shot version of the Model 98 infantry rifle equipped with a bipod and pistol grip. The T-Gewehr could penetrate the armor of any Allied tank used during WWI. Some 15,800 T-Gewehr rifles were manufactured in 1918. Most were destroyed after the war because no one brought them home as war trophies (probably because of it’s size). The massive 39 inch barrel has a fixed, inverted “V” front sight and tangent rear sight graduated to 500 meters. The receiver is marked with the Mauser Banner and dated “1918″.

Estimated Price: $5,500 – $8,500

Lot #: 334

Czechoslovakian Model ZH29

This is a rare example of a Czech Model ZH29 semi-automatic rifle with distinctive, finned, cast, aluminum handguard, European walnut stock, forearm and detachable magazine. The Model ZH29 was one of the first successful military semi-automatic rifles. Introduced in 1929, it was purchased in limited quantities by Ethiopia and Thailand. In 1929, a ZH29 chambered for the .276 Pedersen cartridge was tested by the U.S. Army at Aberdeen Proving Ground as a possible semi-automatic replacement for the Model 1903 Rifle. The ZH29 features a milled steel receiver with a tangent rear sight graduated to 1600 meters.

Estimated Price: $12,000 – $15,000

Lot #: 453

The first impressions I get looking at the rifle is not the distinctive aluminum handguard, but that the bolt carrier looks like it was installed on its side.

Morrill, Mosman and Blair Elgin Cutlass Pistol with Scabbard

An extremely rare example of an Elgin Cutlass Pistol made by Henry Morrill, Silas Mosman and Charles Blair in 1837-38. The Elgin Cutlass Pistol was patented by George Elgin of Macon, Georgia, in 1837. The unique design combined a box-lock percussion pistol with a Bowie type knife. The Elgin Cutlass Pistols were equipped with a distinctive, form-fitted, black leather scabbard with a metal throat. The U.S. Navy contracted for 150 Elgin Cutlass Pistols to arm the Wilkes South Seas Exploring Expedition in 1837. The Wilkes Expedition pistols were made by Cyrus B. Allen and N.P. Ames manufactured the blades. Apparently spurred by the Navy order, the firm of Morrill, Mossman and Blair was established to manufacture Elgin Cutlass Pistols in August 1837. Silas Mosman previously worked as an engraver for N.P. Ames and subsequently returned to work for that firm in July, 1838. In contrast to the Navy cutlass pistols manufactured by N.P. Ames and Cyrus Allen; Morrill, Mosman and Blair manufactured both the pistol and the Bowie blade. This pistol has a round, four inch, .34 caliber rifled barrel with brass front sight blade.

Estimated Price: $18,000 – $25,000

Lot #: 3001

New Jovian Thunderbolt has written a post discussing magazine spring failure

I think the “spring tension is shot” excuse is a catch-all reason that is over used when us amateur gunsmiths run out of ideas. Like the way they blame ball bearings for everything wrong in turbofan aviation maintenance.

[ ... ]

Here is an example of a spring ‘problem’ that wasn’t from the Cooper Commentaries:

“Our distinguished family member J.P. Denis of Belgium reports that he discovered an abandoned MP40, together with several magazines, in a building that was being torn down. This piece had been left unattended for 50 years with all magazines in full compression, and they all worked perfectly. I think this is marvelous. When you think of the degree to which our culture depends upon springs, it is good to know that spring construction is so well understood.”

An interesting post. We really do rely on our magazine springs. Read it here.

…. literally

Post at MP.net

Okay, so we were out on a mission yesterday to provide security/overwatch for a team to do an audit/inspection of a civilian demining company clearing land mines in the Stan.

We get there and are in our vehicles covering the roads for about a half hour. I am sending messages back and forth with my bro who is the TC (Truck Commander) of the vehicle to my rear.

He said he had to poo. I told him he is ****ed because we will be here for another few hours, and he cant get out of the truck because of the mines.

He said he was going to look around in the back for an ammo can.

I thought he was joking.

I told him his truck crew was going to hate him for life…

heh heh
