TO MINIMIZE MALFUNCTIONS (“JAMS”)
Most malfunctions are caused by improper or damaged magazines, incorrect
ammunition, or poor maintenance. RUGER®MODEL 10/22®MAGNUM
& 10/17TMchambers must be scrupulously cleaned at least every 50 shots
(see “Care and Cleaning”, pp. 26 - 27.)
1. If it appears that the gun and magazine are not at fault and that the jam was 
caused by the type of cartridge being used, then try another type.
2. If changing to another type or brand of cartridges does not at once eliminate...

The 22 Long Rifle, 22 Magnum and 17 HMR rimfire
cartridges fire when the firing pin impacts the
relatively soft cartridge case rim, and also can be
“discharged” before it is chambered if its rim
receives a sharp blow. 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.Any jam or feeding problem is a
signal to immediately stop using the gun until it
can be determined...

TO DISASSEMBLE
Make Sure Rifle is Unloaded!
1.With the rifle pointing in a safe direction, remove the magazine, open the bolt
and visually make certain there is not a cartridge in the chamber. Then allow
the bolt to close. The rear sight leaf should be down, and the hammer should
be cocked.
2. Loosen the barrel band screw (B-69) and remove the barrel band (B-68). (Does
not apply to the Sporter Model, Rifle Model, and the 10/17.)
3. Loosen (don’t remove) the take-down screw (B-65).
4. Position the...

REASSEMBLYAgain, Be Sure Rifle is Unloaded!
1. Reassembly of bolt into receiver:
a. To reassemble bolt handle and bolt in the receiver, position the rear end 
(cone pointed) of the recoil spring guide rod in the mating recess near 
the rear right side of the receiver. The recoil spring must be flat against 
the side and “bottom” of the receiver.
b. Maintain the guide rod in its proper position by keeping pressure on the 
bolt handle with the left forefinger and thumb. At the same time, use the 
flat...

After cleaning, always check to be certain that rotor movement and tension are
correct, and that no solvent or debris remain. Do not disassemble the magazine.
Improper reassembly or improper tensioning of the rotor spring can cause a
potentially dangerous malfunction. If you experience a problem with the
magazine, don’t use it. Get a new one.
DAMAGED, NON-STANDARD, OR IMPROPERLY
ASSEMBLED MAGAZINES SHOULD NOT BE USED.
THEY CAN CAUSE THE RIFLE TO MALFUNCTION.

Firing a rifle with oil, grease, or any other material
even partially obstructing the bore may result in
damage to the rifle and serious injury to the
shooter and those nearby. Do not spray or apply
lubricants directly on ammunition. If the powder
of a cartridge is affected by the lubricant, it may
not be ignited, but the primer firing may push the
bullet into the bore where it may be lodged. Firing
a subsequent bullet into the obstructed bore may
damage the rifle and cause serious injury or death
to the...

Never place or store any firearm in
such a manner that it may be
dislodged. Firearms should always be
stored securely and unloaded, away
from children and careless adults. Use
the locking device originally supplied
with this firearm for storage.
The use of a locking device or safety
lock is only one aspect of responsible
firearms storage. For increased safety,
firearms should be stored unloaded
and locked in a location that is both
separate from their ammunition and
inaccessible to children and any...

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. Rusting may occur as a result of the firearm being exposed to
moisture, salt...

ATTACHING SCOPE BASE ADAPTER
To attach Scope Base Adapter to rifle receiver:
1. Retract bolt handle, lock bolt open and push safety to “on” position. Be sure
gun is completely empty.
2. Unscrew the four filler (headless) screws from the receiver. These screws may
be quite tight.
3. Position adapter on receiver and place a base-mounting screw in each hole of
the adapter. Turn each screw until it just catches the threads in the receiver
hole, but don’t tighten the screws at this point.
4. Starting at the...

SIGHT ADJUSTMENT
The folding leaf rear sight is adjustable for elevation. The slide must be moved
one graduation to change the point of impact by approximately one inch at 25
yards. Use a small screwdriver with a blade tip that exactly fits the screw-head.
Loosen the screws only slightly so the slide doesn’t move too freely. Move the
slide in the direction you want the point of impact of the bullet to move. When
the slide is positioned at the desired height, carefully tighten both screws.
