State WarningAs a firearm owner, you accept a set of demandingresponsibilities. How seriously you take theseresponsibilities can be the difference between lifeand death.According to state law, California requires that firearmmanufacturers, distributors and retailers includeconspicuous, specific warnings with firearms sold inthat state.There is no excuse for careless or abusive handling ofany firearm. At all times handle this firearm and allother firearms with intense respect for their power andpotential danger.Please read and understand all of the cautions, warnings,notices, proper handling procedures and instructionsoutlined in this owner’s manual before using yournew firearm.WARNING: You Are Responsible ForFirearm SafetyFAILURE TO FOLLOW ANY OF THE FOLLOWINGWARNINGS COULD RESULT IN SERIOUS INJURYOR DEATH. 11ALWAYS KEEP THE MUZZLE OF YOUR FIREARMPOINTED IN A SAFE DIRECTION EVEN THOUGH YOUARE CERTAIN IT IS UNLOADED.Never point any firearm at anything you do notintend to shoot. Be extremely alert and aware ofall persons and property within the range ofyour ammunition.2NEVER RELY TOTALLY ON YOUR FIREARM’SMECHANICAL “SAFETY” DEVICE. LIKE ANYMECHANICAL DEVICE, A “SAFETY” CAN SOMETIMESFAIL; IT CAN BE JARRED OR INADVERTENTLYMANIPULATED INTO AN UNSAFE CONDITION.The word “safety” describes a firearm’s trigger blockmechanism, sear block mechanism, hammer blockmechanism or firing pin block mechanism.

Make certain the firearm does not inadvertentlycontain any ammunition. Remember, merely removingthe magazine does not mean the chamber is unloaded.Always keep the chamber empty and the “safety” inthe on safe position unless shooting is imminent.Mechanical “safeties” are designed to place yourfirearm in a safer status, and no guarantee can be madethat the firearm will not fire even if the “safety” is inthe on safe position. Mechanical “safeties” merely aidsafe gun handling and are no excuse for pointing yourfirearm’s muzzle in an unsafe direction. See “Operationof the ‘Safety’” on pages 12-13 for instructions on theoperation of this firearm’s “safety.”4Remember, safe gun handling does not stop with yourfirearm’s mechanical “safety” devices, it starts there.Always treat this firearm with the respect due aloaded, ready-to-fire firearm.Wear shooting glasses to protect your eyes from flyingparticles. Allow proper distance (eye relief) betweena scope and your eye when firing a scoped pistol, rifleor shotgun. Do not use unorthodox shooting methodsthat could cause the rearward travel of the slide orbolt of a firearm to contact your eyes, face or hands.Always keep a safe distance between the muzzleof your firearm and any persons nearby, as muzzleblast, debris and ejecting cartridges could inflictserious injury.Some firearms do not have a mechanical “safety.”Many target firearms, lever-action firearms and pistolsdo not have manual “safety” mechanisms. Therefore itis critical to read and understand the owner’s manualfor every firearm which explains the safe operation ofthe firearm.While it is a good idea to “test” your firearm’smechanical “safety” periodically for proper function,never test the “safety” while your firearm is loaded orpointed in an unsafe direction.3ALWAYS WEAR EAR AND EYE PROTECTIONWHEN SHOOTING.Unprotected, repeated exposure to gunfire can causehearing damage. Wear hearing protection (shootingearplugs or muffs) to guard against such damage.Always wear eye protection when disassembling andcleaning any firearm to prevent the possibility ofsprings, spring-tensioned parts, solvents or otheragents from contacting your eyes.WHENEVER YOU HANDLE ANY FIREARM, OR HANDIT TO SOMEONE, ALWAYS OPEN THE ACTIONIMMEDIATELY AND VISUALLY CHECK THE FIREARM’SCHAMBER TO MAKE CERTAIN THAT THE FIREARM ISCOMPLETELY UNLOADED.5 2KEEP ALL FIREARMS UNLOADED DURINGTRANSPORT, EVEN WHEN STORED IN A HOLSTER,GUN CASE, SCABBARD OR OTHER CONTAINER.

6DROPPING OR JARRING A LOADED FIREARM CANCAUSE ACCIDENTAL DISCHARGE.This can occur even with the “safety” in the on safeposition. Be extremely careful while hunting or duringany shooting activity to avoid dropping any firearm.7HUNTING FROM ELEVATED SURFACES SUCH ASTREESTANDS IS DANGEROUS.Doing so may increase the risk of mishandling afirearm. The following rules should always be observedby you and those you hunt with. Always make certainthat the stand being used is safe and stable. Alwaysmake certain that your firearm is unloaded when it isbeing taken up and down from the stand. Alwaysmake certain that your firearm is not dropped fromthe stand, or dropped while it is being taken up ordown from the stand. Remember, a loaded firearmmay discharge when dropped, even with the “safety”in the on safe position.89BEWARE OF BARREL OBSTRUCTIONS.Mud, snow and an infinite variety of other objects mayinadvertently lodge in a barrel bore. It only takes asmall obstruction to cause dangerously increasedpressures that can damage your firearm and causeserious injury to yourself and others.BEFORE CHECKING FOR A BARREL OBSTRUCTION,BE CERTAIN YOUR FIREARM IS COMPLETELYUNLOADED, THERE IS NOT A LIVE CARTRIDGE INTHE CHAMBER AND THE “SAFETY” IS IN THEON SAFE POSITION.After assuring yourself that the firearm is completelyunloaded, open the breech or action and look throughthe barrel to be sure it is clear of obstructions. If anobstruction is seen, no matter how small it may be,clean the bore with a cleaning rod and patch asdescribed on pages 27-29 of this owner’s manual.10 BE ALERT TO THE SIGNS OF AMMUNITIONMALFUNCTION. IF YOU DETECT AN OFF SOUNDOR LIGHT RECOIL WHEN A CARTRIDGE IS FIRED,DO NOT LOAD ANOTHER CARTRIDGE INTOTHE CHAMBER.If your firearm fails to fire, keep the muzzle pointed ina safe direction for a minimum of 30 seconds. Rotatethe ejection area of the firearm away from you,carefully open the action and remove the cartridgefrom the chamber. If the primer is indented, thedefective cartridge should be disposed of in a way thatcannot cause harm. If the primer is not indented, yourSTORE YOUR FIREARM AND AMMUNITIONSEPARATELY, WELL BEYOND THE REACHOF CHILDREN.Take prudent safeguards to ensure your firearm doesnot become available to untrained, inexperienced orunwelcome hands. Store all firearms in secure, lockedcases or a gun safe. Keep your firearm unloaded whennot in use. 3

FIGURE 1Model 70 Controlled Round Feed BoltFIGURE 2Precision-MachinedConed BreechLocking LugsEjector SlotClaw ExtractorAnti-Bind Slotdesign also allows the cartridge to be extracted even if it isnot fully chambered.The Model 70 features the highly popular, Pre-’64 typebolt with claw extractor and Controlled Round Feed,proven under actual hunting and shooting conditions.The Model 70 features a precision-machined conedbreech that aligns the cartridge with the chamber withoutdamaging the bullet point. This improves accuracy andensures smooth, snag-free feeding as the cartridge neckand shoulder are guided into position (Figure 2, page 7).General OperationThe Model 70 is a bolt-action rifle that operates by liftingthe bolt handle, drawing the bolt rearward and thensliding the bolt forward and rotating the bolt handledownward until it stops. This process takes a cartridgefrom the magazine and loads it into the chamber for firing.A manual ejector gives more control over cartridgeejection. The Model 70’s Pre-’64 type design uses a bladesystem that allows you to vary the amount of ejectionforce. Pull sharply rearward and the cartridge ejects clearof the rifle. Pull slowly and easily remove the cartridgefrom the action (Figure 3, page 8).The Controlled Round Feed bolt design is a big part ofthe Model 70 legacy. Its massive claw extractor (Figure 1,page 7) secures approximately ¼ of the cartridge base andfully controls the cartridge as it enters the chamber. This 7

For general parts nomenclature, refer to Figure 4 onpage 9. Figure 5 on pages 10 and 11 covers the generalfeatures and benefits of the Model 70 design.A push feed design with a recessed bolt face and plungerstyle ejector merely pushes the cartridge forward until it isseated in the chamber. It then snaps over the rim of thecartridge, ready for extraction.Throughout this owner’s manual the “action” refersto the mechanism of this rifle which loads and securesthe cartridges in the chamber.Operation of left-hand models is identical, except that thebolt handle and ejection port are located on the left sideof the receiver.Serial NumberThe serial number is located on the right side of thereceiver, just forward of the loading/ejection port.Record the serial number at the front of this owner’smanual for future reference.All operations of the Model 70 are illustrated in thisowner’s manual with a right-hand model.Prior to using live ammunition, familiarize yourselfthoroughly with the operating instructions in thisowner’s manual.
