RIFLE CLEANING

Remember that after scrubbing
with a strong solvent and a bronze
brush there will be a lot of blue gunk
on the next patch through the bore.
Some of that is from the dissolving
brush, some of it is from the bore.
It can be a lot, so don't be shocked.
Also, don't think you have stumbled
onto the secret to doing this fast. (If
you actually do, please share.) All
that blue gunk is a good thing to get
out of the bore, but don't think it
means you are done.
For most aggressive copper
solvents, it is recommended that
they not be left in the bore for more
than 15 minutes. That doesn't mean
you can stop cleaning after fifteen
minutes, only that you need to keep
removing the old solvent and replacing it with fresh. Keep working with
wet patches and brushes to refresh
the solvent often.
Even after the patches start coming out clean, it's possible to have
copper fouling trapped between layers
of powder or carbon fouling. Just to
be sure, clean all the solvent out of
the gun and switch solvents with the
idea that one might get the fouling
that the other does not.
The best approach is to return to
a general-use solvent such as Hoppe's
No. 9 Benchrest. Make sure to remove
all traces of the first solvent before
switching to another solvent.
If it's really fouled, the old benchrest
shooter's trick of Kroil and J-B Bore
Cleaning Compound can help to loosen
things up. Kroil has excellent penetration qualities, so it will work in under
the fouling. The J-B Bore Cleaning
Compound is slightly abrasive, so it
cleans the crud and copper out, but
it's not abrasive enough to damage
the bore. In fact, with regular use it
helps smooth the bore.
Wet a few patches and saturate
the bore with Kroil, then let it soak
for a while. Wet a tight-fitting patch
with Kroil and then coat it with J-B
compound. Run it through the bore
a bunch of times, at least 20 passes,
and twice that is better. Check the
patch often and add more J-B and
Kroil as needed. If the patch gets
worn, replace it.
