4. Replace the assembled barreled action into the stock, making sure that it is
fully seated to the rear of the Stock. With a screwdriver, snug down the Front
Mounting Screw, but do not tighten completely at this point.
5. Make sure the Hammer (CS01700) is cocked and the Safety is “ON” (safe). To
reinstall the Trigger Housing, make sure the assembly lugs on the Trigger
Housing engage the assembly notches in the Receiver. Pivot the Trigger
Housing into the stock, and then install the Trigger Housing Screw.
6. Now securely tighten both the Front Mounting Screw and the Trigger Housing
Screw.
7. Replace the Handguard atop the Barrel.
8. Replace the Barrel Band and tighten its screw securely.
9. Cycle the Slide Handle and Safety a few times to be certain the components
are correctly assembled. Put the Safety back “ON” (safe) and keep it there.
MAGAZINE INSPECTION AND CARE
Check the magazine frequently. The rotor must move freely and have adequate
tension so that each cartridge is quickly raised to the feeding position. The .44
magnum magazine is automatically tensioned (rotor wound 1 1/2 turns) if
properly assembled.
To test the rotor tension, load one cartridge into the magazine and then firmly
press against the side of the cartridge case. Remove your finger quickly. The
cartridge should instantly and fully move in to the feeding position. If it does
not, the magazine should be cleaned. If cleaning does not restore proper rotor
tension, do not use the magazine.(NOTE: After testing, remove the test
cartridge).
When cleaning is necessary, use a solvent that will not rust the metal
components or adversely affect the plastic magazine box. After the magazine has
been soaked in solvent to loosen foreign matter, be certain to shake it vigorously
(with the loading opening away from you) to remove solvent or residue from
within the magazine.
After cleaning, always check to be certain that rotor movement and tension are
correct, and that no solvent or residue remains. 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.

CARE AND CLEANING
Make Sure Gun is Unloaded!
Before cleaning, be certain the rifle and its magazine contain no cartridges.
At regular intervals, or whenever the rifle has been exposed to sand, dust,
extreme humidity, condensation, immersion in water, or other adverse
conditions, disassemble, clean and oil it. Proper periodic maintenance is
essential to the reliable functioning of any firearm.
To clean the rifle, proceed as follows:
1. Disassemble (field-strip) the rifle to the extent described on pages  18 - 21.
2. Using a cleaning rod, run a solvent-wetted patch through the bore several
times. Then attach a solvent-wetted bristle brush to the rod and run it back
and forth the full length of the bore as many times as necessary to remove
grease and dirt from the bore and chamber. Clean bore with dry patches and
examine. Bore fouling can contribute to reduced accuracy, and grease
accumulation in the chamber can interfere with proper feeding of cartridges
from the magazine.
3. Using powder solvent on a clean patch or bristle brush, remove powder
residue from all components of the mechanism. After cleaning, run a dry
patch through the bore, then follow with a patch that is very lightly oiled.
Wipe all surfaces clean with cloth, then wipe all surfaces with a patch or cloth
that has been very lightly oiled.
DAMAGED, NON-STANDARD, OR IMPROPERLY
ASSEMBLED MAGAZINES SHOULD NOT BE USED.
THEY CAN CAUSE THE RIFLE TO MALFUNCTION.

the text above, the
magazine should not be
disassembled.  
						

							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 shooter and those nearby. Use
lubricants properly. You are responsible for the
proper care and maintenance of your firearms.
IMPROPER LUBRICATION
DESTROYS GUNS
24
WARNING – LUBRICATION
4. NOTE: Only a light application of oil is needed to provide adequate lubrication
of moving parts and to prevent rust. Excess accumulations of oil tend to
attract particles of dust and dirt and may congeal in cold weather which can
interfere with the safe and reliable functioning of the rifle.
STORAGE
GUNS SHOULD NOT BE STORED LOADED!
USE THE LOCKING DEVICE SUPPLIED WITH THE RIFLE FOR STORAGE.
(SEEPAGE3)
Do notstore the rifle in a leather case or scabbard. Leather attracts moisture,
even though it may appear to be dry.
TO RENDER THE RIFLE INOPERATIVE FOR SAFE STORAGE
With the muzzle pointed in a safe direction, remove the magazine, open the
bolt, and check the chamber to be sur
e the rifle is completely unloaded!Remove
the trigger housing screw and pivot the trigger housing forward and out of the
stock. The trigger housing assembly contains most of the firing mechanism.
Store the rifle and the trigger housing assembly in different locations. When
disassembled in this manner, the rifle is inoperable. It is impossible to fire the
rifle until the trigger housing assembly has been correctly replaced into the rifle.
To reassemble the rifle for firing, reinstall the trigger housing and replace the
trigger housing screw to secure the trigger housing to the receiver. Check to be
sure the bolt, trigger, and safety mechanisms can be operated fully and freely.
The rifle is now reassembled and can be loaded and fired normally. 
						

							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 other
unauthorized person.
STORE SECURELY & UNLOADED
WARNING – STORAGE
While the rifle is less likely to be used by unauthorized persons when
disassembled in the above manner, it is always safest to store a firearm with
the supplied locking device correctly installed, or to store the firearm in a gun
safe or other secure location, away from children and unauthorized adults.
Guns should always be stored securely, unloaded
and separate from their
ammunition.
25 
						

							SIGHT ADJUSTMENT
Shooting to determine the setting of the elevation slide (aperture) should be
done from a bench rest and over a measured distance.
Since the impact point and accuracy of different .44 magnum ammunition can
vary considerably (a 180 grain bullet load may impact the target 15” higher than
a 300 grain bullet load at 50 yards), to accomodate the majority of ammunition
the open sights are factory zeroed at 50 yards with standard U.S. factory-loaded
240 grain jacketed bullet ammunition.
26
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. Disassemble one ring and reassemble over the scope body between the turret
and the eyepiece. Remember - the lug on the base should be on the front side
of the scope.
2. Install the four top screws. Do not tighten.
3. Disassemble the other ring and install it on the forward section of the scope
tube with the lug forwardly also. Install the four top screws. Again, do not
tighten.
4. Assemble the rings to the receiver with the lugs engaging the recesses in the
top surface of the receiver. Tighten the clamp nuts so that the rings are locked
to the semicircular cuts on the sides of the receiver.
5. Rotate the scope until cross-hairs are aligned properly and slide scope to
desired eye relief. then tighten the eight top screws each a bit at a time to grip
the scope body.
6. Sight in according to the directions with your scope.
7. If ejected cases strike the scope, try using higher scope rings or different
ammunition. If this condition persists, you should use the supplied Ruger
Scope Shield (part no. SP17339).
SUGGESTED SIGHT
PICTURE
The front sight is aligned in the
center of the rear sight aperture
(“peep”) and the target (bullseye) is
positioned to appear as if it is
sitting on top of the front sight. 
						

							27
The rear sight is adjustable for both windage and elevation. Lateral (windage)
adjustment is made by loosening the Rear Sight Windage Lock Screw (with the
hex-head wrench provided with the rifle) until the sight base requires finger
pressure to be moved. (See illustration below). Move the sight in the direction
you wish to move the point of impact. Before moving the sight, pencil mark an
index line on the sight base and on the receiver so that the amount of sight
movement can be detected. After desired positioning of the sight base has been
achieved, tighten the lock screw firmly.
WINDAGE ADJUSTMENT:Loosen windage lock screw. To move the bullet
impact point to the left
, move the rear sight base to the left. To move the
bullet impact point to the right
, move the rear sight base to the right. Be sure
to carefully retighten lock screw after adjustment.
ELEVATION ADJUSTMENT:To move the bullet impact point upor down, move
the elevation slide (the “peep”) by loosening both
elevation lock screws (using a
small screwdriver with a blade tip that exactlyfits the screw-heads) 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, be sur
e to carefully retighten both screws.
