3 WARNING! “Children are attracted to and can operate firearms that can cause severe injuries or death. Prevent child access by always keeping guns locked away and unloaded when not in use. If you keep a loaded firearm where a child obtains and improperly uses it, you can be fined or sent to prison.” ADVERTENCIA! 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: “A los niños los atraen las armas de fuego y las pueden hacer fun- cionar. Ellos pueden causarses lesions graves y la muerte. Evite que los niños tengan accesso a las armas de fuego guardándolas siempre con llave y descargadas cuando no las esté utilizando. Si usted tiene un arma de fuego car- gada en un lugar en que un niño tiene acceso a ella y la usa inde- bidamente, le pueden dar una multa o enviarlo a la carcel.” Connecticut: “UNLAWFUL STORAGE OF A LOADED FIREARM MAY RESULT IN IMPRISONMENT OR FINE.” Florida: “IT IS UNLAWFUL, AND PUNISHABLE BY IMPRISON- MENT AND FINE, FOR ANY ADULT TO STORE OR LEAVE A FIREARM IN ANY PLACE WITHIN THE REACH OR EASY ACCESS OF A MINOR UNDER 18 YEARS OF AGE OR TO KNOWINGLY SELL OR OTHER- WISE TRANSFER OWNERSHIP OR POSSESSION OF A FIREARM TO A MINOR OR A PERSON OF UNSOUND MIND.”
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. It is a cr imeto store or leave a loaded firearm in any location where an individual knew or should have known that an unsupervised minor would gain access to the firearm. Store your firearm responsibly!” Massachusetts: “WARNING FROM THE MASSACHUSETTS ATTORNEY GENERAL: This handgun is not equipped with a device that fully blocks use by unauthorized users. More than 200,000 firearms like this one are stolen from their owners every year in the United States. In addition, there are more than a thou- sand suicides each year by younger children and teenagers who get access to firearms. Hundreds more die from acciden- tal discharge. It is likely that many more children sustain seri- ous wounds, or inflict such wounds accidentally on others. In order to limit the chance of such misuse, it is imperative that you keep this weapon locked in a secure place and take other steps necessary to limit the possibility of theft or accident. Failure to take reasonable preventive steps may result in inno- cent lives being lost, and in some circumstances may result in your liability for these deaths.” “IT IS UNLAWFUL TO STORE OR KEEP A FIREARM, RIFLE, SHOTGUN OR MACHINE GUN IN ANY PLACE UNLESS THAT WEAPON IS EQUIPPED WITH A TAM- PER-RESISTANT SAFETY DEVICE OR IS STORED OR KEPT IN A SECURELY LOCKED CONTAINER.” 4
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 STOR- AGE. 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 PER- SONS.” North Carolina: “IT IS UNLAWFUL TO STORE OR LEAVE A FIREARM THAT CAN BE DISCHARGED IN A MANNER THAT A REASONABLE PERSON SHOULD KNOW IS ACCESSIBLE TO A MINOR.” Texas: “IT IS UNLAWFUL TO STORE, TRANSPORT, OR ABAN- DON AN UNSECURED FIREARM IN A PLACE WHERE CHILDREN ARE LIKELY TO BE AND CAN OBTAIN ACCESS TO THE FIREARM.” Wisconsin: “IF YOU LEAVE A LOADED FIREARM WITHIN THE REACH OR EASY ACCESS OF A CHILD YOU MAY BE FINED OR IMPRISONED OR BOTH IF THE CHILD IMPROPERLY DISCHARGES, POSSESSES, OR EXHIBITS THE FIREARM.” ***************** ***** Please check with your licensed retailer or state police for addi- tional warnings which may be required by local law or regula- tion. Such regulations change constantly, and local authorities are in the best position to advise you on such legal matters. 5
6 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 27. NEVER INSTALL LOCKING DEVICE INSIDE TRIGGER GUARD !WARNING – LOCKING DEVICES DO NOT INSTALL INSIDE TRIGGER GUARD INSTALL LOCK AS SHOWN HERE

NOMENCLATURE OPERATION OF SAFETY The RUGER MODEL 77/22® ,MODEL 77/17 &MODEL 77/44TM rifles have a three position safety. The safety selector is located at the right of the bolt sleeve. The safety selector can be moved from the “Fire” position to its two other posi- tions (“Load-Unload” and “Safe”) only when the firing pin is cocked. Fully raising the bolt handle cocks the firing pin. The bolt handle can be raised and lowered only when the safety selector is in either the “Fire” or the “Load-Unload” position. When the safety selector is in the Figure 1.Components frequently referred to are identified. In this illustration the cocking piece is shown cocked (protruding from the rear of the bolt sleeve) revealing the disassembly hole in the lower portion of the cocked piece. The bolt stop (on the left side of the receiver) permits the bolt to be with- drawn simply by pressing down lightly with the thumbnail. The safety selector (show in the “Fire” posi- tion) should be in the “Load-Unload” position when the bolt is being removed or being installed.
10 “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.” WARNING: When manipulating the safety selector, DO NOT HAVE ANY FINGER INSIDE THE TRIGGER GUARD! When the safety selector is in the “Fire” position and the trigger is pulled, the rifle will fire. The safety selector should always be in the “Safe” position except when the gun user is actually firing or unloading the rifle. The safety selector should unfailing- ly be moved to the “Safe” position when the gun user ceases firing. SAFETY POSITIONS Figure 2.Safety selector in “FIRE”(full forward) position. The safety selector should be moved to this position only when the gun user is actually firing the rifle.When the safety is in the fire position, it is referred to as being “off.” (When the safety is in the “SAFE” position, it is referred to as being “on.”)Figure 3.Safety selector in “LOAD-UNLOAD” (middle) posi- tion. The safety selector should be in this position when the bolt is being cycled to load a cartridge, or to unload a live round. As soon as a cartridge is chambered, the safe- ty selector should be moved to the “SAFE” position unless the rifle is to be fired immediately.Figure 4.Safety selector in “SAFE”(full rearward) position. The safety selector is fully nested in the groove in the cocking piece. When the safety selector is in this position, the bolt handle cannot be raised. The curved arrow on the bolt sleeve indicates the direction and motion of the safety selector to bring it to the “SAFE” position. Keep the safety in this position except when actually loading, unloading, or firing. !WARNING – MANUAL SAFETY Keep the safety on unless actually firing. Always move the safety fully to its intended position and check it. The safety has three positions –“SAFE,” “LOAD-UNLOAD,” and “FIRE.” 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 and the chamber and magazine are empty. KNOW HOW TO USE THE SAFETY 3 2 1 SAFELOAD- UNLOADFIRE
11 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. If the safety does not function properly, or if the selector seems to move too easily, or if the safety selector does not seem firmly positioned in any of its three positions, the rifle should be discontinued from use and returned to the Newport Product Service Department for repair (see p. 30). AMMUNITION RUGER MODEL 77/22® rifles are chambered for many of the most popular factory-loaded cartridges manufactured in accordance with U.S. industry prac- tice. The particular caliber for each rifle is rollmarked on the barrel. Use car- tridges only of the designated caliber that is marked on the barrel. Please see AMMUNITION WARNING, p. 12 and LOADING WARNING on p. 15. The RUGER MODEL 77/22 ® is chambered for, and designed to properly function as a repeating rifle with the .22 caliber Long Rifle rimfire cartridge, standard, high velocity or hyper-velocity, manufactured to industry standards. The .22 Short, .22 Long and .22 SHOT cartridges can be fired in the model 77/22 ®rifle, but such cartridges must be introduced by hand directly into the chamber. It should be noted that extensive use of the .22 Short cartridge can cause a ‘ring’ to be cut in the chamber which may interfere with the extraction of Long Rifle cartridges. The RUGER MODEL 77/17is chambered for the .17 HMR Hornady Magnum Rimfire cartridge only. Do not use any other rimfire ammunition in this rifle! The RUGER MODEL 77/22 ® MAGNUMis chambered for the .22 Winchester Magnum Rimfire cartridge only, both jacketed and hollow point. Do not use any other .22 caliber or any other rimfire ammunition in this rifle, as burst cases and the release of hot powder gases can result. The RUGER MODEL 77/22 ® HORNET is chambered onlyfor the center- fire .22 Hornet cartridge. Do not attempt to use any .22 rimfire (short, long, long rifle, or magnum) ammunition nor anyother centerfire .22 ammunition (.222, .223, etc.) in this model. WARNING:DO NOT ATTEMPT TO LOAD .22 SHORT, .22 LONG, .22 SHOT OR ANY OTHER TYPE OF .22 CALIBER CARTRIDGE (OTHER THAN THE .22 LONG RIFLE) INTO THE MAGAZINE OF THE 77/22 ® RIFLE. THE USE OF OTHER CARTRIDGES IN THE MAGA- ZINE 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. DO NOT ATTEMPT TO LOAD ANY .22 RIMFIRE AMMUNITION INTO THE .22 HORNET MAGAZINE. DO NOT FIRE .17 HMR CARTRIDGES IN .22 MAG- NUM RIFLES! !
