4. Inspect the bore from both ends for
leading by looking through bore toward
light. Leading will appear as dull longitu-
dinal streaks and is usually more pre-
dominant near the muzzle and just for-
ward of the chamber.
5. A normal amount of leading can be ex-
pected with today’s high velocity loads
and improved wads but this is not seri-
ous. If or when leading should become
heavy, it can be removed with a brass
bore brush. Make sure a choke tube is
installed. Spray the bore or the bore
brush with a good powder solvent, and
scrub the bore until leading is removed.
To prevent brass bristles from breaking
off, the brush should be pushed com-
pletely through the bore before being
withdrawn.
6. After leading has been removed, the
bore should be wiped dry with a clean
patch, and then a lightly oiled patch run
through it for preservation.
