State-By-State Warnings Certain states require by law that their own specified warning notices in larger-than-normal type be conspicuously included by the manufacturer, distributor, or retail dealer with firearms sold in that state. Sturm, Ruger sells its products in compliance with applicable laws and regulations. Because our products may be sold in these states, we include the following: California: ! WARNING ! ADVERTENCIA “A los niños los atraen las armas de fuego y las pueden hacer funcionar.
Maine: “ENDANGERING THE WELFARE OF A CHILD IS A CRIME. IF YOU LEAVE A FIREARM AND AMMUNITION WITHIN EASY ACCESS OF A CHILD, YOU MAY BE SUBJECT TO FINE, IMPRISONMENT OR BOTH. KEEP FIREARMS AND AMMUNITION SEPARATE. KEEP FIREARMS AND AMMUNITION LOCKED UP. USE TRIGGER LOCKS.” Maryland: “WARNING: Children can operate firearms which may cause death or serious injury.
New Jersey: “IT IS A CRIMINAL OFFENSE TO LEAVE A LOADED FIREARM WITHIN EASY ACCESS OF A MINOR.” New York City: “THE USE OF A LOCKING DEVICE OR SAFETY LOCK IS ONLY ONE ASPECT OF RESPONSIBLE WEAPONS STORAGE. ALL WEAPONS SHOULD BE STORED UNLOADED AND LOCKED IN A LOCATION THAT IS BOTH SEPARATE FROM THEIR AMMUNITION AND INACCESSIBLE TO CHILDREN AND ANY OTHER UNAUTHORIZED PERSONS.
! WARNING – LOCKING DEVICES 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.
FIREARMS SAFETY-YOUR RESPONSIBILITY SAFETY MUST BE THE FIRST AND CONSTANT CONSIDERATION OF EVERY PERSON WHO HANDLES FIREARMS AND AMMUNITION. This Instruction Manual is designed to assist you in learning how to use and care for your RUGER MODEL 77/22®, MODEL 77/17 & MODEL 77/44TM rifles properly. Only when you are certain you fully understand the Manual and can properly carry out its instructions should you practice loading, etc. with live ammunition.

The receiver on all versions of the Model 77/22®, Model 77/17, and the 77/44TM rifle incorporates integral scope mount bases (see illustration below). The Model 77/22®, Model 77/17, and the 77/44TM rifles come with a set of two Ruger 1” steel scope rings. The R model does not have open sights. The 77/22®RS and 77/44TMRS come with open sights - a gold bead front sight and a folding leaf rear sight which is adjustable for elevation and windage.
“Safe” position, the bolt handle is locked in the closed (full down) position in order to prevent inadvertent lifting of the bolt handle and to ensure that the rifle will be ready to fire when the safety is taken “off”. Practice (with an unloaded rifle) moving the safety selector to the three positions until you know the position of the safety selector for the three modes– “Fire,” “Load-Unload,” and “Safe.
This safety selector is held in each of its positions by a plunger that is under spring tension. Therefore, the gun user should frequently check the position of the safety selector to be certain it has not been inadvertently moved.
The RUGER MODEL 77/44TM is chambered only for the centerfire .44 Magnum cartridge and should not be used with any other .44 caliber ammunition. Most .44 Magnum ammunition factory loaded to U.S. industry specifications is suitable for use. However, “Medium Velocity” non-jacketed ammunition may not give optimum accuracy and is not recommended. WARNING: SOME TYPES OF LONG RIFLE CARTRIDGES HAVE BLUNT-NOSE OR SHARP-SHOULDER BULLETS WHICH CAN INTERFERE WITH SMOOTH AND RELIABLE FEEDING FROM MAGAZINE TO CHAMBER.
AMMUNITION (CARTRIDGES) NOTICE 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.
10. Raise the bolt handle, draw the bolt fully to the rear, then smoothly push the bolt forward so that a cartridge is stripped from the magazine and chambered. (Note: If the cartridge does not readily strip from the magazine, or if the cartridge tends to jam while being chambered, discontinue the loading procedure. Extract and eject the ‘problem’ cartridge and remove the loaded magazine from the rifle.
WARNING: REMEMBER THAT EACH TIME A CARTRIDGE IS FIRED AND A NEW ONE IS CHAMBERED. THE SAFETY SELECTOR IS IN THE “FIRE” POSITION. THEREFORE, IF THE RIFLE IS NOT GOING TO BE DISCHARGED IMMEDIATELY AFTER THE CARTRIDGE IS CHAMBERED, MOVE THE SAFETY SELECTOR FULLY BACK TO THE “SAFE” POSITION. ! 14. To Single Load: The rifle can be used as a single shot rifle in the absence of a magazine or for safety or training purposes. To do so, follow steps 1 - 3, p. 13.
! WARNING – HANDLING Never carry the rifle loaded with the safety selector in the “FIRE” position. If dropped or struck with the safety off, the rifle may fire. Such a discharge can occur with or without the trigger being directly struck or touched. Never rest a loaded rifle against any object (wall, fence, vehicle, tree, etc.) because there is always the possibility that the rifle will be jarred or slide from its position and fall with sufficient force to discharge. Keep safety on unless actually firing.
8. If the rifle is not cocked, as when a fired cartridge case is in the chamber or in the event of a misfire, carefully raise the bolt handle fully upward to cock it. (Do not retract the bolt at this point). Now, put the safety in the “LoadUnload” position, and repeat steps 3 - 6, p. 16.
TO EXTRACT AND EJECT A CHAMBERED CARTRIDGE When the bolt is operated by hand, there can be a failure to extract the cartridge from the chamber, or a failure to eject the cartridge clear of the rifle. These failures usually are the result of the bolt not being pulled rearward vigorously, coupled with an accumulation of bullet lubricant in the chamber. From the foregoing it is clear that the gun user must: 1. Always visually check the chamber after opening the bolt to eject a chambered cartridge.
! WARNING – MALFUNCTIONS ➞ If a cartridge hangs up, jams, or binds when being chambered or when being fed from the magazine into the chamber, do not attempt to force it into the chamber by pushing or striking the bolt handle. Most failures of a cartridge to feed or to chamber are caused by improper loading of the magazine or ammunition that is incorrect or defective.
To minimize the possibility of such occurrences the gun user should: –Use ammunition of the correct caliber and type which is loaded to U.S. Industry Specifications. Do not use cartridges that are deformed, or cartridges that have been reloaded. –Clean and lubricate the gun in accordance with the instructions in this manual. –Learn to correctly operate the bolt and how to properly load and empty the chamber and magazine.
WARNING: If a spring or plunger become lost do not use a substitute. Springs of correct tension are vital to the safe and reliable performance of firearms. Before starting disassembly, remove the sling, scope and rings and place the rear sight blade in its down flat position. DISASSEMBLY (Rifle Must Be Unloaded Prior To Disassembly) 1. Keep the rifle pointed in a safe direction! Put the safety in the “load-unload” position, then, remove the magazine. 2.
! CAUTION: The bolt sleeve assembly is intended to be a permanent assembly and should not be disassembled. The parts are under great spring pressure and if disassembled could fly apart with sufficient force to cause serious injury. Also, special tools are required to correctly reassemble this part. 5. To remove the stock: (Be certain the bolt and magazine have been removed from the rifle.) NOTE: On the K77/22RP & RSP models, disregard step “b” and magazine well liner in step “c”, below. a.
REASSEMBLY (Again, Be Sure Rifle Is Unloaded) 1. To replace the bolt stop: a. Replace the bolt stop plunger and bolt stop plunger spring. (Be certain that the step flats on the plunger match the flats on the mating surface of the bolt stop.) b. Depress the bolt stop plunger and replace the bolt stop on the pivot. 2. To replace the safety assembly: a. Place the safety selector detent and safety selector detent spring into the hole in the receiver. b.
f. Replace the breech block retaining pin. Flats on the breech block retaining pin must align with the slot in the breech block when the retaining pin is installed. g. Rotate the bolt sleeve assembly in counter-clockwise position until the cocking piece engages small notch in the bolt. h. Remove the pin or nail from the cocking piece.
Exploded view of the 77/22® Long Rifle magazine components. This illustration is included to show the relationship and names of the magazine components. The 77/22® Magnum, .17 HMR, 77/22® Hornet, and 77/44TM magazines are similar. As noted in the text above, the magazine should not be disassembled. Magazine Components (.22LR Shown) When cleaning is necessary, use a solvent that will not rust the metal components or adversely affect the plastic magazine box.
Insert rod from the chamber end of the barrel and push firmly so the patch or brush emerges from the muzzle. Don’t reverse the rod when a brush or patch is being used – it may bind. Don’t use patches or brushes dripping with solvent or oil. Use rod and brushes with care so as not to damage gun. 1. Disassemble (field-strip) the rifle to the extent described on pages 21 - 22. 2. Push-pull a solvent-wetted patch through the bore several times.
STORAGE GUNS SHOULD NOT BE STORED LOADED! USE THE LOCKING DEVICE SUPPLIED WITH THE RIFLE FOR STORAGE. (SEE PAGE 6) Do not store the rifle in a leather case or scabbard. Leather attracts moisture, even though the case may appear to be perfectly dry.
MAINTENANCE OF STAINLESS STEEL RIFLES Firearms and components made of stainless steel are relatively more resistant to corrosion than those of blued steel. However, in the interest of proper operation and long life of a stainless steel firearm, inspect it frequently and clean, lubricate and apply an appropriate rust preventative. Sometimes discoloration occurs from perspiration or from contact with some types of gun cases.
ATTACHING RUGER SCOPE RINGS Each Ruger telescope ring is a mated assembly of a top and a base. Do not mix the parts of the two ring assemblies as they are not interchangeable. On the underside of each mounting ring assembly there is an integral lug, located off center with respect to the front and back sides of the mount. The lug is nearer to the front surface. By reference to the lug, the mounting ring can be correctly assembled with the front of the ring toward the muzzle of the rifle. 1.

THE BASIC RULES OF SAFE FIREARMS HANDLING We believe that Americans have a right to purchase and use firearms for lawful purposes. The private ownership of firearms in America is traditional, but that ownership imposes the responsibility on the gun owner to use his firearms in a way which will ensure his own safety and that of others. When firearms are used in a safe and responsible manner, they are a great source of pleasure and satisfaction, and represent a fundamental part of our personal liberty.
A safe direction must take into account the fact that a bullet may penetrate a wall, ceiling, floor, window, etc., and strike a person or damage property. Make it a habit to know exactly where the muzzle of your gun is pointing whenever you handle it, and be sure that you are always in control of the direction in which the muzzle is pointing, even if you fall or stumble. Keep your finger off the trigger until you are ready to shoot. 3. FIREARMS SHOULD BE UNLOADED WHEN NOT IN USE.
5. BE SURE OF YOUR TARGET BEFORE YOU SHOOT. Don’t shoot unless you know exactly where your bullet is going to strike. Be sure of the bullet stop behind your target, even when dry-firing with an unloaded gun. If you are in the field hunting, do not fire at a movement or noise. Take the time to be absolutely certain of your target before you pull the trigger. 6. WEAR SHOOTING GLASSES AND HEARING PROTECTORS WHEN YOU SHOOT.
8. DON’T SHOOT AT A HARD SURFACE, OR AT WATER. Bullets can glance off many surfaces like rocks or the surface of water and travel in unpredictable directions with considerable velocity. 9. NEVER TRANSPORT A LOADED FIREARM. Firearms should always be unloaded before being placed in a vehicle. A suitable carrying case or scabbard should be used to carry an unloaded firearm to and from the shooting area. 10. AVOID ALCOHOLIC BEVERAGES WHEN SHOOTING. Don’t drink until the day’s shooting is over.
A BRIEF ACCOUNT OF AN EXTRAORDINARY ACHIEVEMENT: RUGER FIREARMS One of the few American firearms manufacturers whose management has remained unchanged since starting in business, Sturm, Ruger & Company, Inc., had its beginning in a small machine shop occupying a rented frame building in Southport, Connecticut. In January, 1949, with an initial investment of only $50,000 and an idea, William B. Ruger and Alexander M. Sturm started production of a .
WHY NO WARRANTY CARD HAS BEEN PACKED WITH THIS NEW RUGER FIREARM The Magnuson-Moss Act (Public Law 93-637) does not require any seller or manufacturer of a consumer product to give a written warranty. It does provide that if a written warranty is given, it must be designated as “limited” or as “full” and sets minimum standards for a “full” warranty. Sturm, Ruger & Company, Inc.
