You can visit the U.S. Military Dates of Manufacture page on OldGuns.net. Select whether your firearm is a handgun or a long gun and choose the appropriate link to be directed to the lookup tool. Then, simply search for the date your firearm was created by typing its serial number in the box.

This 12-bore is proofed under the Rules of Proof in force at the London Proof House from 1904 - 1925. 'Smokeless' powders were now widely used to the Britain. So, guns marked with these stamps show 'NITRO PROOF' unless they have been proof tested for black powder only.

All firearm manufacturers use a data stamp on their rifles and ammunition. For rifles the data stamp is often located on the left or right side of the barrel.

NITRO PROOF - the mark was introduced in 1896 and discontinued in 1954. NP with crown over- the Birmingham Nitro Proof mark, introduced in 1896.

A gun dealer can run a serial number search, but may charge a small fee for doing so. The documentation that came with the gun will also have this information. In many cases, this will come from the owner's manual.

Definition of proofmark

: a distinctive symbol stamped into the metal of the barrel or other part of a firearm to indicate that testing of the part bearing the stamp by firing proof loads has been carried out.

A "proof round" is an ammunition assembly designed to be used in proof testing; this can use a fixed cartridge, a semi-fixed cartridge, or separately loaded projectile, charge and primer. A "proof shot" is a special projectile used in a proof round or other projectile weapons, electromagnetic guns for example.

A: Check the barrel of your gun. The gun will be stamped 'steel shot' and have a fleur de lys proof mark. This shows it will handle high performance steel. These cartridges should only be used in shotguns that have passed the special steel shot proof and bear the words “steel shot” and a fleur de lys proof mark.

Barrel stamp – A stamp pressed into the side of the barrel of a firearm that typically states the manufacturer, the gauge or caliber, and the chamber size.

What kind of gun do I have by serial number? ›

You can look up a gun by its serial number using certain resources like the NRA website and the Blue Book of Gun Values. Additionally, many firearms manufacturer websites have databases of their guns, and you can look up the serial numbers of firearms they manufacture.

A headstamp is the markings on the bottom of a cartridge case designed for a firearm. It usually tells who manufactured the case. If it is a civilian case it often also tells the caliber: if it is military, the year of manufacture is often added.

Enfield, Rifle, Carbine. Enfield, Rifle, Carbine. 1. LE. Limited Edition.

No Sights. Rifle, Sight, Supply.

Contact your local police department or sheriff's office to run a gun serial number search if you are looking to purchase a pre-owned gun from a dealer. Police records will indicate whether the gun has been used in a crime or has been reported lost or stolen.

In 1968, the Gun Control Act (GCA) imposed numerous additional requirements in the arena of gun manufacture. As per the GCA, all firearms manufactured or imported into the United States are required to bear a serial number.

Locate the Gun Serial Number

There is no typical serial number. For example, a Browning serial number can range in length from eight to ten characters, a Glock number is only five characters long. Serial numbers can contain both numbers and letters. A serial number is stamped in metal so it doesn't wear easily.

Tracing Process

Firearms tracing begins when ATF or another law enforcement agency discovers a firearm at a crime scene and wants to learn where it came from. NTC receives the trace request and uses the gun's serial number to identify its original manufacture or importer.

At the time of purchase, the code or serial number would be recorded along with the purchaser's information by a licensed dealer. Later, when a bullet or cartridge case is found at a crime scene, the bullet or spent cartridge could be quickly traced back to the purchaser.

What year is Marlin 336? ›

Marlin 336 year of manufacture

It is also valid for determining most other Marlin firearm build dates from 1946 to the present. Starting in 1973, the year of manufacture can be determined by subtracting the first two digits of the serial number from 100: Example: SN 2512345 would have been made in 1975 [100 - 25 = 75].

Proofing is a type of (potentially destructive) testing whereby a firearm is discharged with appropriate dimension ammunition that has been overloaded with powder on purpose. Shooting a round overcharged with powder produces higher than normal pressure inside the barrels and action when the gun is fired.

A centerfire bullet can travel several miles. Small shot can travel 200–350 yards. Larger shot can travel over 600 yards.

Its three major activities are: proof, safety and de-activation. Proof is the process of testing the safety of a gun barrel. It is still done as it has been since the Company was established in 1637: by firing the gun with an over-pressure charge of powder. If the gun survives undamaged, it will be safe to shoot.

Overpressure ammunition, commonly designated as +P or +P+, is small arms ammunition that has been loaded to produce a higher internal pressure when fired than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated by a proof round.

The +P designation for ammunition has absolutely nothing to do with the potential for the ammunition to be more effective at stopping bad guys. The +P designation only means that the ammunition is loaded to a higher pressure.

Proofs allow you to check the layout, color breaks, fold positions and other details so you can make necessary changes before your order goes to press. This is especially important if the job involves typesetting, color separation, or any other layout work done after the job leaves your office.

Current guidance when using standard steel shot is to shoot no tighter than half choke. Using tighter than half choke risks damaging the barrel. It is quite difficult to blow up a barrel, and a blockage in the barrel itself is usually the cause.

With the advent of the 1991-92 season, steel shot will be required for goose and duck hunting throughout the nation. The switch to steel is being made because spent lead pellets accidentally ingested kill millions of waterfowl annually.

Steel shot could damage a shotgun barrel if the right precautions aren't taken. Some shotgun barrels aren't compatible with steel shot. Choke tubes that are too tight can also cause issues with large steel pellets.

What information does the data stamp on the barrel of a shotgun indicate? ›

Breech marks can also show no obvious pattern. They may have a stippled or mottled appearance as seen below. Now back to ejector marks. Ejector marks are sometimes created when cartridges or cartridge cases are ejected from the action of a firearm.

A barrel will produce individual markings in addition to a bullet's land and groove impressions as the bullet passes through, and it is these unique markings that an examiner evaluates to determine whether a given bullet was fired from a particular firearm.

The Easiest Way to Identify a Gun Model Type

Firearms manufacturers, you see, stamp a certain amount of information on the outside of the gun. Long guns tend to have that information stamped directly on the barrel. Pick up a rifle or shotgun and you'll see it, usually where the barrel meets the rest of the gun.

The serial number includes information related to the date and location of the weapon's manufacturing. Additionally, if the weapon is stolen, it can help link the firearm to the original owner when the government places the serial number into a national database.

The bullet is propelled along the barrel of the gun by gases created by burning gunpowder. Shotgun ammunition is sized by gauge, a number that represents how many pellets, each the size of the diameter of the barrel of the weapon, can be made from a pound of lead.

RP stands for Remington-Peters (ammunition headstamp)

The vast majority of ammunition is marked at the time of manufacture for internal (proper safety, quality control and record-keeping) and external requirements (clients' demands based on regional or national requirements).

SP-RP stands for "spire point - recoil proof," and the design of this bullet eliminates the problem of tip deformation during recoil.

Is SKS on ban list? ›

The government conveniently left the SKS off of the banned list because they know a large number of people own them, and they weren't prepared to spend what little political capital they have left with law-abiding gun owners.

A two or three letter code on the left side of the barrel identifies the month and year of manufacture. The first letter identifes the month, the other letter(s) identify the year.

Look up the pistol's full serial number -- including all letters and numbers -- in the back section of the "Standard Catalog of Smith & Wesson" book. These listings inform you of the pistol's date of manufacture, based on the serial number.

You can look up a gun by its serial number using certain resources like the NRA website and the Blue Book of Gun Values. Additionally, many firearms manufacturer websites have databases of their guns, and you can look up the serial numbers of firearms they manufacture.
