Your Model 70 will function better and more reliably

over a longer period of time if it is properly maintained

and kept clean. Clean your firearm after every day of

shooting, and more often if it becomes excessively dirty.

A minimum cleaning includes wiping down the firearm

and oiling key parts. Regular maintenance will also

include cleaning the barrel.
If you encounter a function problem be sure to give your

firearm a thorough cleaning to see if it solves the problem

before seeking the services of a Winchester Authorized

Repair Center or our Service Center in Arnold, Missouri

or a qualified gunsmith.
1. Remove the bolt as explained previously.
2. Inspect the chamber and bore for powder fouling.

A normal amount of powder residue can be expected

and is not serious. It can usually be removed with

a patch saturated with nitro solvent.

Use a cleaning rod with a tip and patch large enough

for a snug fit in the bore. Insert the rod and patch into

the barrel at the breech end and run it back and forth

several times. Care should be exercised to ensure that

the cleaning rod does not strike the crown of the

muzzle, as damage to this area can affect the accuracy

of your rifle.

If, or when, fouling should become heavy, it can be

removed with a brass bore brush. Dip or spray the

brush with nitro solvent and scrub the chamber and

bore until the fouling is removed. To prevent brass

bristles from breaking off, the brush should be pushed

completely through the barrel before being withdrawn.

To maintain the utmost accuracy of your rifle it is

recommended you clean the bore with a copper

solvent. Modern bullet jackets are made mainly of

copper. Residues from copper bullet jackets stick to

the barrel and require more frequent cleaning.

Magnum calibers will require more frequent

inspection and cleaning. Swab the bore of your rifle

with a good copper solvent using the manufacturer’s

recommended procedure.

3. After all fouling has been removed, the chamber and

bore should be wiped dry. When the bore is dry, pass a

slightly oiled patch through it for preservation. A fine,

light gun oil is recommended.

4. Inspect the barrel and chamber to be certain no

patches have inadvertently been left in them. Remove

any that remain.

5. Use a small brush or rag to remove dirt or other

foreign matter from inside the receiver and other parts

of the action. Lightly lubricate all moving parts with a

high-quality, light gun oil. Use oil sparingly, a very

light film is sufficient. A fine, light gun oil is ideally

suited for this purpose.

NOTICE! do not Pour large quantities oF oil into
the receiver or other Parts. it can drain into
the wood and soFten it, causing PerManent
daMage and loosening oF the stocK.

8. Tighten the screws snugly, but do not overtighten.
9. Mount your scope rings and scope as outlined in the

instructions supplied with your scope rings and/or

scope. Always make sure you have the proper eye relief.

Always make sure that the saddle crossbolts and cap

bolts are fully tightened before using your firearm.

Be especially careful when cleaning firearms with

camouflage, Dura-Touch

®

Armor Coating and other

special finishes. Always prevent these surfaces from

coming in contact with cleaning solvents, barrel scrubbers

and other strong chemicals. It is preferable to clean these

surfaces with a light gun oil containing no solvents or

with a damp cloth and mild dish soap (be sure to keep

water out of the action). When cleaning your firearm’s

bore and action, protect the external finishes from any

contact with chemicals used. Also, avoid any contact between

external finishes and other strong chemicals like those found

in DEET-containing insect repellents, sunscreens, etc.

Damage to camouflage, Dura-Touch and other finishes caused

by chemicals is irreversible and not repairable.
