Winchester Repeating Arms 63 (Historic Manual) - Manual (Page 17)

Take down your Model 63 into the barrel/receiver
half and the buttstock half as explained previously.
Take extra care to protect the rifling at the muzzle
of your rifle from damage (which can affect accura-
cy). A muzzle protector (available at most good gun
shops) is always a good idea.
1. Use a cleaning rod with a tip and patch suitable
for the size of your Model 63’s .22 caliber bore.
Make sure the patch is large enough for a snug fit in
the bore. Insert the rod and patch into the barrel at
the muzzle end and run it back and forth several
times. Although it is possible to remove the bolt
from the Model 63, it requires special tools and some
expertise — and is therefore, not recommended.
2. Push the operating sleeve fully in and lock it (and
the action) rearward to inspect the chamber and
bore for brass, copper, lead and powder fouling. A
normal amount of powder residue can be expected
and is not serious. It can usually be removed by
repeating step one, using a patch saturated with sol-
vent. If or when fouling should become heavy, it can
be removed with a brass bore brush. Dip or spray the
brush with solvent and scrub the chamber and bore
until the fouling is removed. To prevent brass bris-
tles from breaking off, the brush should be pushed
completely through the bore before being with-
drawn. Because you are cleaning the barrel with the
breech bolt in place it is helpful to use a brush that
has a shorter overall length so it is possible to push it
past the chamber. Keep the operating sleeve (and
bolt) locked rearward during the cleaning procedure.

S UGGESTIONS
Your Model 63 will function better and more reli-
ably over a longer period of time if it is properly
maintained and kept clean.
BEFORE PERFORMING ANY CLEANING
PROCEDURES, ALWAYS MAKE CERTAIN
THERE ARE NO CARTRIDGES IN THE
CHAMBER, MAGAZINE OR ACTION/FEED
AREAS.
You should clean your Model 63 after every day of
shooting and more often if it becomes excessively
dirty.
A minimum cleaning includes wiping down the
action and oiling key parts. Most regular mainte-
nance will also include cleaning the barrel. If you
encounter a function problem be sure to give your
gun a thorough cleaning to see if it solves the prob-
lem before seeking the services of one of our
Authorized Repair Centers, our service facility or a
competent gunsmith. To clean your firearm, adhere
to the following general guidelines.
C LEANING P ROCEDURES —
BE CERTAIN YOUR GUN’S CHAMBER
AND MAGAZINE ARE UNLOADED.
ALWAYS WEAR PROTECTIVE SAFETY
GLASSES DURING ALL CLEANING PRO-
CEDURES. KEEP AMMUNITION AWAY
FROM THE CLEANING AREA. DO NOT
TEST THE FUNCTION OF YOUR FIREARM
WITH LIVE AMMUNITION.
