Ruger 77/50 - Manual (Page 29)

Firing a rifle with oil, grease, a bullet, 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 black
powder. If the powder charge is affected by the
lubricant, it may not be ignited, but the energy
from the percussion cap may be sufficient to push
the bullet into the bore where it may become
lodged. Firing the obstructed bore may damage
the rifle and cause serious injury or death to the
shooter and those nearby. In the event of a
misfire, always reseat the bullet fully onto the
powder charge before re-capping. Use lubricants
properly. You are responsible for the proper care
and maintenance of your firearm.

7. Thoroughly scrub bolt component parts in pan, flush with very hot water,
or ammonia-based window cleaner, rinse and then wipe dry. Scrub the
front of the bolt face with a toothbrush to remove all traces of powder and
cap fouling.
8. Soak the breech plug in very hot, soapy water or an ammonia-based
window cleaner. Scrub its threads with a toothbrush. Thoroughly dry the
breech plug, making sure the flash hole through the nipple is clean and
dry.
9. Inspect all parts (including bolt, barrel, receiver, trigger, etc.) to be sure
that these are clean and dry. Pay particular attention to the breech plug
threads inside the barrel.
10. Oil the bore and all parts thoroughly with a good quality gun oil, then re-
assemble. However, avoid lubricating the striker, striker spring, or the
inside of the bolt, to avoid oil spattering when firing or sluggish ignition in
cold weather. Remember to lubricate the breech plug/nipple assembly
threads with a good quality black powder gun grease prior to reassembly
(See page 30).
11. The outside (exposed) metal parts should be wiped down and lightly oiled
to remove fouling and prevent rusting.
NOTE: Several firms offer Black Powder solvents and these may be used in place of
the soap and hot water solution. However, not all smokeless powder solvents will
render the fouling left by Black Powder non-corrosive. Be sure you use a solvent
specifically intended for black powder fouling, hot, soapy water, or an ammonia-
based window cleaner, followed by a good gun oil.
Sometimes, lead build-up can occur in the barrel throat at the muzzle of the barrel,
and in the bore. If ‘leading’ is noted in your rifle, clean it out before it builds up and
interferes with reliable functioning and accuracy. A special ‘lead removing’ cleaning
tool (for bore and chamber) is available from gun stores.
