NOTE: The following warning applies to RUGER®MODEL 10/22

MAGNUM rifles only

WARNING – LOCKING DEVICES

DO NOT INSTALL

INSIDE TRIGGER GUARD

This firearm was originally sold with a key-operated locking device. While it can help provide secure storage for your unloaded firearm, any locking device can fail. All guns are designed to fire if they are loaded and the trigger is pulled. Therefore, never install the

locking device inside the trigger guard or in any way that it can possibly pull the trigger! Do not

leave the keys in the lock.

The ultimate responsibility for secure storage of any firearm must depend upon its owner and his or her individual circumstances. Guns should be securely stored unloaded, in a secure location, separate from their ammunition.

See “Storage Warning”, page 22.

GENERAL INFORMATION

AND MECHANICAL CHARACTERISTICS

The RUGER®MODEL 10/22®MAGNUM differs from the RUGER MODEL 10/22®CARBINE in caliber .22 long rifle in the following partic-

ulars:

●

Ammunition - It is chambered for the larger and more powerful .22

Winchester Magnum Rimfire (.22 WMR) cartridge only;

●

Magazine - It uses a larger 9-shot magazine, first introduced in the

Ruger 77/22 magnum rifle, to handle this longer cartridge;

●

Receiver - It uses a special longer chrome-molybdenum steel

receiver, which also incorporates -

●

Integral Scope - Unlike the screw-on aluminum “tip-off” scope mount Mount Bases base furnished with standard Ruger 10/22 rifles, the

Ruger 10/22 Magnum features steel scope bases integral to the receiver, which accept the patented Ruger scope rings (furnished at no extra charge).

●

Bolt - The Ruger 10/22 Magnum bolt is manufactured from

a dense tungsten alloy, in order to give the bolt adequate mass required to function correctly with the more powerful .22 Winchester Magnum Rimfire cartridge.

The RUGER

MODEL 10/22®MAGNUM is an autoloading rifle cham-

bered for the .22 Winchester Magnum Rimfire cartridge. It is recoil (“blowback”) operated and uses a 9-shot rotary magazine. Retracting the bolt handle cocks the internal hammer and compresses the recoil spring. When the bolt is manually released, it moves forward (driven by the recoil spring), strips a cartridge from the magazine, if a loaded magazine is in place, and chambers the cartridge. The bolt is held against the chambered cartridge by the recoil spring.

When the trigger is pulled, the hammer is released and strikes the firing pin. The firing pin indents the cartridge case rim and ignites the priming compound inside the rim. This ignites the powder in the cartridge case and a great volume of gas is instantly generated, which acts on the interior of the cartridge case in all directions.

Because the bullet offers the least resistance, it moves out of the cartridge case and exits the muzzle. The bolt then moves rearward automatically, extracting and ejecting the fired cartridge case, and at the same time cocking the hammer and compressing the recoil spring, etc., as described above. Once the trigger is released, the rifle is ready to fire again.

Each time the trigger is pulled and released, the same cycle is repeated until there are no more cartridges in the magazine or in the chamber.

The rifle will fire if there is a cartridge in the chamber and the trigger is pulled, whether or not there is a magazine in place! Removing the magazine does not unload the rifle. Never assume the rifle is unloaded. Visually inspect the chamber and the magazine each time the rifle is handled to be certain there are no cartridges in either.

All models include the following features with which the gun user should be thoroughly familiar.

OPERATION OF SAFETY

The RUGER®MODEL 10/22®MAGNUM has a cross-button safety which is located in the forward portion of the trigger guard (Figure 1). The safety can be operated only when the hammer is cocked.

The safety is “on” when it protrudes fully from the right side (the bolt handle side) of the trigger guard assembly, as shown in Figure 1. In this position the sear is blocked, and the gun cannot be fired from a normal pull on the trigger.

The safety should always be in the “on” (safe) position except when the shooter is actually firing the gun. The safety should be moved to the “on” position whenever the shooter ceases firing, even temporarily.

The safety is “off” (fire) when it protrudes from the left side of the trigger guard

SAFETY IN “ON” (SAFE) POSITION

assembly, as shown in Figure 2. When the safety is off, the red band shows on the safety button, but do not totally rely on the appearance of the red band to indicate that the safety is off. In poor light or if dirt is present, the red band may not be visible. If the safety is “off” and the trigger is pulled, the rifle will fire.

Figure 2. The underside of the trigger guard section of the rifle. In this illustration the safety is shown in the “off” (fire) position. The position of the safety and red band indicate the safety is “off.” It should be in this position only when you are actually firing at a target.

The safety is held in its “on” or “off” position by a plunger that is under spring tension. When the safety is moved to either the “on” or “off” position, a distinct “click” should be heard. Frequently check the position of the safety to be certain the safety has not been inadvertently moved. If the safety seems to move too easily, or if the click is not heard when the safety is moved, stop using the rifle and return it to the Newport Product Service Department for repair (see p. 24).

WARNING – MANUAL SAFETY

Keep the safety on unless actually firing. Always move the safety fully to its intended position and check it. The safety is not “ON” unless it is completely “ON”. Never depend on a safety mechanism or any other mechanical device to justify careless handling or permitting the rifle to point in an unsafe direction. The only “safe” rifle is one in which the bolt is open, the chamber is empty, and there is no magazine in the gun.

KNOW HOW TO USE THE SAFETY

THE BOLT LOCK

The bolt lock is located in the forward section of the trigger guard (see Figure 1, p. 6). The bolt lock is the manually operated means of retaining the bolt in the rearward (open) position. When the bolt is locked open, the rifle is in an inoperative safe condition for inspection of the chamber, cleaning, etc.

To lock the bolt open: Retract the bolt handle to its extreme rearward position and, while holding it there, press in on the lower pressure on the bolt handle and it will move forward a fraction of an inch, and then be locked in its open position.

Press Back to Lock Bolt Open Press Up to Close Bolt

To release the bolt: Retract the bolt handle to its extreme rearward position and then press in on the upper move fully forward.

NOTE: Simply retracting the bolt will not disengage the lock. The bolt lock must be deliberately pressed up while the bolt is held fully to the rear. Only then will the bolt close when released. This is designed to prevent accidental release of the bolt from its open position.

AMMUNITION

.22 WMR

.22

Long Rifle

.22 Long

.22 Short

The RUGER®MODEL 10/22®MAGNUM is chambered for, and designed to properly function with, only the .22 Winchester Magnum Rimfire cartridge, both jacketed and hollow point, manufactured to U.S. industry standards. Do not use any other .22 caliber ammunition in this rifle as burst cases and the release of hot powder gas can result. See “.22 Magnum Ammunition Warning”, below.

USE ONLY FACTORY AMMUNITION LOADED

TO U.S. INDUSTRY STANDARDS

However, your choice of ammunition may affect the functioning of this firearm. Ammunition manufacturers use different powders, bullets and case specifications. If you find that you are experiencing feeding and extraction problems, switching to another type or brand of .22WMR ammunition may improve the situation.

WARNING –.22 MAGNUM AMMUNITION

Use only standard Winchester Magnum Rimfire (.22WMR) ammunition loaded to U.S. Industry specifications. Do not

fire .22 short, long, or long rifle cartridges in this rifle or load them into the magazine - they are of smaller case diameter and otherwise vary in size from the larger .22WMR cartridge. They can split or burst when fired in the larger magnum chamber, releasing hot powder gasses and particle fragments out of the action at high speed, possibly resulting in injury to the shooter or bystanders.

WE SPECIFICALLY DISCLAIM RESPONSIBILITY FOR ANY DAMAGE

OR INJURY WHATSOEVER OCCURRING IN CONNECTION WITH, OR

AS A RESULT OF, THE USE IN ANY RUGER FIREARMS OF FAULTY,

OR NON-STANDARD, OR “REMANUFACTURED” OR HAND-LOADED

(RELOADED) AMMUNITION, OR OF CARTRIDGES OTHER THAN THOSE FOR

WHICH THE FIREARM WAS ORIGINALLY CHAMBERED.

WARNING – AMMUNITION

Death, serious injury, and damage can result from the use of wrong ammunition, bore obstructions, powder overloads, or incorrect cartridge components. .22 cases are very thin and sometimes split when fired. Always wear shooting glasses and hearing protectors.

MAGAZINE

The 9-shot .22WMR magazine for the Ruger Model 10/22 Magnum is longer than the 10-shot .22 long rifle magazine for standard Ruger 10/22 carbines. Do not attempt to use standard 10/22 magazines in the 10/22 Magnum rifle or load .22 short, long, or long rifle ammunition into the .22 magnum magazine. They will not function correctly and are unsafe to use in .22 Magnum rifles (see “.22 Magnum Ammunition Warning”, p. 9).

.22 LONG RIFLE, .22 SHOT, OR ANY OTHER TYPE OF .22

CALIBER CARTRIDGE (OTHER THAN THE .22 WMR) INTO THE MAGAZINE OF THE 10/22® MAGNUM RIFLE. THE USE OF OTHER THAN .22 MAGNUM CARTRIDGES IN THE MAGAZINE CAN CAUSE POTENTIALLY DANGEROUS JAMS AND MALFUNCTIONS RESULTING IN DAMAGE TO THE FIREARM AND INJURY TO THE SHOOTER AND OTHER PERSONS. TAKE CARE TO USE THE CORRECT CARTRIDGES.

LOADING THE MAGAZINE

Use only clean .22 Winchester Magnum Rimfire (.22WMR) ammunition manufactured to U.S. Industry specifications, in good condition. (See Notice and Warnings in other sections of this manaual pertaining to ammunition).

To load the magazine, press the rim of the cartridge against the magazine rotor at the widest section of the magazine throat until the cartridge enters far enough to be pushed to the rear end of the magazine. Each succeeding cartridge is pressed against the body of the top cartridge and slid to the rear of the magazine until a maximum of nine (9) cartridges are in the magazine.

NOTE: The 9-shot Ruger 77/22 Magnum magazine is the same as, and is interchangeable with, the 9-shot Ruger 10/22 Magnum magazine.

WARNING: SOME TYPES OF .22 MAGNUM CARTRIDGES HAVE

BLUNT-NOSE OR SHARP-SHOULDER BULLETS WHICH CAN

INTERFERE WITH SMOOTH AND RELIABLE FEEDING FROM MAGAZINE TO CHAMBER. SUCH CARTRIDGES SHOULD NOT BE USED BECAUSE THEY MAY DISCHARGE BEFORE BEING FULLY CHAMBERED AND THEREBY POSSIBLY INJURE THE SHOOTER AND THOSE NEARBY. THE SHOOTER MUST BE ALERT TO THIS POTENTIALLY DANGEROUS SITUATION AND SHOULD AT ONCE DISCONTINUE THE USE OF ANY CARTRIDGE WHICH APPEARS TO BE THE CAUSE OF FEEDING PROBLEMS OR JAMMING. KEEP THE CHAMBER AND MAGAZINE CLEAN (SEE “CARE AND CLEANING”, P. 21).
