Slimline Electronic Ear Muffs

Hear and Protect Hear normally up to 85 db Electronically reduces & protects hearing  Protects hearing above 85 db Able to hear normal conversations and sounds to 85 decibels.  Over 200 hours of battery life. Auto-adjust headband. Solid state circuit. Rotary on-off volume knob.
HOW THE ELECTRONIC EAR MUFFS WORK

These electronic ear muffs are a high standard ear muff in design, they are made to feel light and comfortable for all day use. They can be used as standard ear muff when the electronic component is not turned on and will passively reduce noise like any normal ear muff. They have a standard noise reduction rating of 29 decibel and are a Class 5.
Once turned on the microphone, located at the top of the ear muff, will pick up and amplify ambient noise. If some one standing next to you talks, their voice will be amplified through the speakers in both ear muffs. Should there be a loud noise, such as a firearm, the electronic ear muffs will automatically cut out and block the loud noise. The electronic ear muffs are designed to attenuate noise about 85 decibels, meaning that they will block out instantly, once the noise reaches a certain level. The electronic ear muffs allow you to control the volume level of ambient noise around you. On the shooting range with constant loud reports, the electronic ear muffs will block this noise. For range instructions or to communicate with another person, you can instantly hear them speak.
At the range or anywhere ear protection is constantly required, but you also need to hear instructions from others or you wish to be more aware of the ambient sound around you, these electronic ear muffs are what you need.

Accurate Firearm Design

Gas Operated Actions. In this type of self-loading rifle the expanding force of the powder gas is utilized in a different manner from any of the foregoing to operate the mechanism. A small hole is drilled through the lower wall of the barrel into the bore, and as the bullet passes this hole a portion of the gas rushes into the hole and down into a gas piston below the barrel. The rod of this piston pushes back an operating rod which is connected with the breech bolt and a counter recoil spring. The operating rod first operates a cam to rotate the bolt or tip the bolt which unlock its locking lugs by which it was tightly locked to the barrel, and then pushes the bolt back to its stop, extracting and ejecting the fired case, compressing the mainspring, and cocking the firing pin. The counter recoil spring then pulls or mainly pushes the bolt, and  operating rod, and gas piston forward. As the bolt moves forward it pushes the topmost cartridge from the magazine into the chamber, and firmly locks itself to the barrel ready to fire again.
If the gas port in the barrel is to close to the chamber, the gas at that point will still be at  peak pressure, and will drive the piston violently to the rear, giving a more severe reaction and which tends to tear the extractor through the rim of the case, or tear the head off the case. With the Garand rifle this gas port is located only about an inch in rear of the muzzle, at which point the gas pressure is very much less, the piston blow and movement is not so violent, the action is smoother, and yet there is sufficient power to extract a fired case, even if it is dry it does not to be lubricated.  Of course they can be nearer to the chamber than that but either there is an adjustable mechanism as on the FN Fal, Enfield SLR or the hole is small as in the AK series of rifles. Either way the bullet has surely left the muzzle before the piston starts to the rear and before the bolt starts to unlock, the push to the rear being continued by the residual pressure. Locating the gas port and piston close to the muzzle, however, necessitates a long forearm of military type to encase the piston and the long operating rod.
The mechanism of the new Winchester short piston throw action (as in.30  M1 Carbine, Ruger Mini 14) is slightly different. The gas port is only slightly forward of the chamber, and the piston rod moves to the rear only about 1/10 inch when the gas enters the cylinder. The operating rod, held against the piston rod by the counter recoil spring, receives a quick, severe blow from the piston rod, and under the impetus of this blow moves to the rear and operates the mechanism as above. The action is like that seen in the lawn game of croquet where the two balls are placed touching each other. The foot is pressed hard on one ball (the piston rod) and that ball is struck a blow by the mallet (the gas). That ball does not move, or moves only a very slight amount, but the other ball (the operating rod) flies across the lawn. This style of mechanism is used in the Winchester (Carbine Williams) .30 M1 Carbine. With this rifle, it is not necessary to use a long forearm to house the piston and operating rod, and this lends itself to the design of a neater and lighter handier type of firearm.
In the early days of the gas operated mechanism, which were also the days of the chlorate primer, considerable trouble was experienced from the rusting and carbon (fouling) of the gas port and piston. Lately, however, with the introduction of the non-corrosive primer, and of powders giving less fouling, most of this trouble has disappeared, and due to the relaxation of the clearing regimes this caused a massive defect during the early Vietnam  M16 period as they all need cleaning.
Cleanliness is next to Godliness, Soldiers who do not clean, see God sooner rather than later.
Cleaning must still be done. Any armourer who has just cleaned the gas cylinder piston and piston plug of the rifles used in combat will assure you that the second coming has not arrived yet, and there is more black carbon in those pistons than the fires of hell.  Both gas port and piston should receive some small lubrication at the same time as when the bore of the rifle is cleaned with solvent and lubricated with an oiled patch. These two systems of gas operation appear to be much better adapted for military and sporting shoulder rifles than any of the other mechanisms described to date.
Next Edition Gas operated piped instead of pistons such as the AG 42 b Ljungman and AR 15 actions.

It’s a week since I received a copy of “Range Officers Hand Book” and since that time I am nearly at the half way mark. I’m amazed at the at the number of subjects you have covered making it one of the most informative books to be added to my collection. It must have taken you a considerable amount of time and experience to publish the book with information not available in other popular Gunsmith manuals. I would recommend the book to “Range Officers” and anyone interested in the sport of target shooting and hunting.

Norinco Model 213 ‘Tokargypt’ 9 shot Semi Auto

The Model 213 original basis was designed by John Moses Browning, the world famous firearm designer. In the late 1920s the Colt /Browning mechanism was redesigned by Russian, Feoder Tokerev, simplified for mass production and chambered in the powerful 7.62×25. It used the Mod 1911 swinging link, short recoil system.
To enable easy maintenance the hammer and lock mechanism can be removed as a single assemble. To improve the Browning feed system the ammunition feed lips are machined into the frame rather than relying on pressed tin. Which on a battlefield where magazines lips do not get the best attention is a great advantage in reliability and makes the magazines cheaper to produce. It was an extremely tough, reliable and powerful pistol and was later modified by Hungary for export to Egypt this was known as the Tokagypt. The pistol differs from the Tokarev in being chambered for the 9mm Parabellum, and a fitted safety catch (WHICH SHOULD NEVER BE RELIED UPON) as well as the half cock safety.

As can be seen by the inset photo the barrels and chambers are all chrome plated. It has a plastic wrap around grip stock, instead of the Tokerev ‘bakelite’ and a finger piece type floor plate on the magazine, which improves your chances of quickly getting it out and getting another one in after someone has rammed one in covered in mud. The M 213 Chinese version of this also has a chrome plated barrel shown in the above photograph. These are brand new unfired but have the usual scratch marks and rough corners as shown in the photographs. As standard the barrels are a millimetre short for club licences so are fitted with a slightly longer barrel. The steel is excellent and once a few surfaces, such as slides, are polished they are a slick an easy pointing pistol. Eight rounds in the magazine.

UNDERSTANDING RELOADING AMMUNITION

Bullets
Early endeavours in the realm  of balancing core hardness with jacket thickness and strength in bullets created a new ballistic science. They wanted the nose of the bullet to yield, to produce reasonably good expansion at reduced velocities; yet, wanted the body of the bullet strong enough to resist break-up under high-velocity short range impact. With additional hype and a few refinements, this basic design is with us still today, probably more bullets adhere to these factors than any other. The refinements consist generally of tapered bullet jackets (thin at the point, thick over the body); longitudinal serrations or grooves (inside or outside) and notches or scallops around the jacket mouth; thin, soft metal protective caps over the otherwise-exposed lead at the nose, like Winchester Silver tips. All major manufacturers produce superb bullets embodying one or more  features that will hold together reasonably well for those under-100-yard shots and still produce adequate expansion out to 300 yards in all but the lightest game animals.
Bullet expansion is promoted two ways, and encouraged by several others. Most common is the simple soft point with the jacket cut away at the point to expose a portion of soft core. Second consists of punching a hole into the point of the bullet along its center line, allowing the jacket to come right up to the mouth of the cavity, the hollow point. Generally, the lower the bullet’s velocity, the greater core exposure or cavity size required to insure expansion. At very high velocities even the tiniest exposure or hole can produce violent expansion.
In an attempt to secure uniform and concentric expansion, jacket mouths are sometimes scalloped, cut part way through, cut through, or weakened in various ways as shown in the manufacturers brochure. All are supposed to be unique, like Solomon said, There is nothing new under the Sun.
Various forms of protection have been applied to the bullet point, both to streamline it for better velocity retention, and to prevent handling, feeding, recoil, and firing damage to exposed lead. Probably the best known design is the Winchester-Western “Silvertip.” This consists of a thin, soft-alloy cap inserted in the mouth of the jacket to cover the core. Another is the Remington “Bronze Point” which consists of a separate, sharp conical point seated in the core. Upon impact, it acts as a wedge to promote expansion.
Both the above methods have been employed in a modified form by various foreign manufacturers with apparently equal success.
However, in the period between the two world wars, European makers attempted to achieve better control over bullet expansion by various means. One was the DWM “Strong-Jacket” which utilized a very thick and heavy section near the jacket base. In its rear third, the jacket was so thick as to reduce core diameter by over one-half. The intention, and reasonably successful, was to insure that the jacket could not roll back completely to the base and that roughly the rear half of the bullet would always remain intact to insure penetration, even though the forward portion of the bullet might be torn off entirely. RWS took an entirely different approach with its “H-Mantel” which utilized a two-part core and a folded jacket. The rear portion of the core was of quite hard lead, the front portion soft. At a point just below the top of the hard core, the jacket was turned in upon itself and folded under pressure to form in effect a partial partition. It was intended that the rear portion of the bullet from the partition rearward would always retain essentially its original shape and insure penetration regardless of what happened to the other part. This, too, was reasonably successful. In the U.S.A., numerous designs to achieve the same ends were proposed, most popular of which was probably the Remington “inner-belted” whose jacket contained a thickened portion near the middle. This thick “belt” was accomplished by first drawing the jacket in the usual fashion, then swaging an additional ring of jacket material on the outside, so that when the bullet was brought to proper exterior dimensions, a thick ring was formed. To a degree, this accomplished the same end as the RWS H-Mantel. Many other designs were attempted, but none achieved any truly great acceptance other than the Winchester “Silvertip” which utilized a very soft and thin protective cap over the lead point projecting from the jacket. Charles Newton designed a “wire-point” bullet which used a thin but strong piece of steel wire inserted in the center of the point to reinforce it against close-range expansion.
However, it was not until the 1950’s that a truly multiple-range bullet design was developed to the point of commercial success and acceptance. The brainchild of John Nosler, it is called the “Nosier Partition Bullet” and in original form contained a completely solid partition located midway in the bullet jacket. This was accomplished by actually machining the jacket from solid copper rod, a most uneconomical method of manufacture. The forward portion of the jacket was relatively thin and filled with a soft lead core; the rear quite thick and with a hard core. In this form, the front portion would expand at any reasonable velocity, while the rear portion then assumed the characteristics of a full-jacketed wadcutter and remained intact under even the most severe impacts to insure deep penetration. Nosier Partition Bullets are currently made from lengths of copper tubing which are impact extruded to form the partition. As a practical manufacturing matter, the partition cannot be made completely solid without significantly increasing production costs. It provides all-range performance at a level of consistency and reliability that cannot be obtained with conventional design. Granted, in spite of advanced production techniques and shortcuts, the partition bullet still costs nearly twice as much to make as the conventional type.  In the last ten years a lot of hunters who feel they need better have chosen Barnes or Nosler type bullets which are a superb bullet but due to the high expense they are never likely to ever displace what are called the “open-cup” designs. Shooters who feel that their type of hunting and game justifies the increased cost of Barnes or Nosier bullets are quite willingly pay it.
