f. Replace the breech block retaining pin. Flats on the breech block retain-
ing 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. If the breech block does
not rotate freely about 1/16” in both directions, then reinsert the pin or nail
in the cocking piece hole and check to be certain that the breech block retain-
ing pin is fully seated. Only when the bolt is correctly assembled should it be
inserted into the receiver.
i. Insert the bolt into the receiver.
REGARDING ACCURACY: The accuracy of any rifle can vary depending upon the
make and type of cartridges used in it. Such being the case, if your RUGER
MODEL 77/22
®
, MODEL 77/17, or MODEL 77/44
TM
rifle does not per-
form to expectations, it is advisable to try several brands and types of cartridges to
determine which one delivers the best accuracy, before proceeding further. If your
rifle is not as “accurate” as you believe it should be, before concluding that some
serious fault exists, run the following checks:
1. Be certain the front mounting screw and the rear mounting screw are snugly
tightened.
2. Be certain the bore is clean and free from accumulated fouling (deposited by
powder and lead bullets). See the “Care and Cleaning” section of this Manual,
pp. 25 - 26.
3. Check the sights, or scope mounting system, for tightness, setting and align-
ment.
4. Be certain the two barrel retainer screws are fully tightened.
If everything is tight, the bore is clean, the sights are properly aligned and secure
but the accuracy problem persists, DO NOT alter the stock bedding in any way.
Do not scrape away wood, and do not bed with “glass,” plastic, epoxy, etc. Once a
rifle stock has been altered, it cannot be reworked by our Product Service
Department. If you still have an accuracy problem, write a brief letter to our
Product Service Department, 411 Sunapee Street, Newport, New Hampshire 03773
and describe the nature of the problem based on the use of factory-loaded car-
tridges – not reloads. You will receive a prompt response from us and if indicated,
detailed instructions with regard to the return of the rifle.
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. At the time
of manufacture, proper rotor tension is set by rotating the magazine cap nut until
the r
otor stops turning. Then the nut is turned an additional 1 1/4 turns beyond
the ‘stop’ position.
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 car-
tridge should instantly and fully move into 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).
