If your initial thought was that moly-coated bullets and barrel
treatments were simply a fad to go by the wayside, think again. Today, most
commercial and specialty bullet manufacturers are offering moly-coated
projectiles, and sales are sky-rocketing.
With moly-coated bullets and
barrels your customers may experience longer periods of accuracy between
cleanings. But like in all other cases, cleaning is a necessity.
is here to stay until technology replaces it with something better for those
who shoot a lot. And, your customers are going to want to know about it. In
this Cleaning Clinic, we'll take a closer look at preparing a barrel for use
with moly and address routine bore maintenance for moly-treated
barrels. Pre-Moly Barrel Preparation: Getting Down To Bare
Assuming most first-timers will be using moly in a seasoned
barrel, let's go from there. Make it clear to your customer that nothing is
gained by spreading moly over a contaminated bore surface. Stress the
importance of starting out with a clean bore. Nobody enjoys it, but a
good-old-fashioned, elbow grease cleaning removes all traces of lead and copper
jacket fouling and sets the framework for superior results with moly
Tackle this job by selecting a standard, bronze bore brush
one caliber oversize, or use our new
or Heavy Weight
bore brushes in the correct size to match your caliber. The Double-Tuff and
Heavy Weight fit tightly and provide a superior scrubbing action. Be prepared
to push a little harder than with conventional brushes – the heavy gauge
bristles don't flex much and retain their diameter, so you'll see fantastic
results and in less time.
Start by using your primary cleaner and
scrubbing out the powder fouling. Next, drench your nylon brush with a proven
copper solvent such as Sweet's 7.62

go with J-B®
Non-Embedding Bore Cleaning Compound
worked into a bore mop or a patch
wrapped around your bore brush (nylon or bronze). Again, to ensure a good, snug
fit, go oversize one caliber if you decide to use a mop. These cleaning methods
will remove the toughest fouling, even the built-up crud that hides in the
tooling marks and heat stress cracks caused by shooting.
customers to follow the manufacturer's recommendations closely, especially when
using ammonia-based cleaners that can harm the bore when left there too long.
If you’re using an ammonia-based cleaner, stick with the nylon brushes.
When you’re comfortable that the bore is free of lead, powder and copper,
give it the once-over with your favorite copper solvent to ensure those
blue-green patches are a thing of the past. How To Treat Your
Barrel With Moly Bore Paste
Wrap a cleaning patch around a
brush one bore size smaller than your barrel. Rub a liberal amount of Brownells
Moly Bore Treatment Paste into the patch. Warming the barrel with a hot air gun
or hair dryer can improve the effectiveness of the treatment.
bore with Brownells Moly Bore Treatment Paste until you feel a slight "drag" to
your cleaning rod (usually about twelve to fifteen passes through the bore.)
Run a dry patch ten to twelve passes through the bore to both remove any excess
Moly Bore Treatment Paste, and burnish in the Moly Bore Treatment Paste.
Routine Cleaning When Using Moly
moly-treated barrel requires no voodoo magic. Claims, that removing too much
moly during a cleaning session will drastically degrade accuracy, are
essentially unfounded. How often to clean is largely dependent on barrel
quality, caliber, powder choice, number of rounds fired, etc. However, when to
clean is less subjective. Teach your customers to learn and judge the shooting
characteristics of their rifles. With moly, the time to clean is when the level
of bore fouling becomes detrimental to accuracy. It's just that simple.
Lets face it, less efficient, overbore cartridges such as the .17 Remington and
6mm-284 can leave behind enough fouling in 20 rounds to cause a noticeable
drop-off in accuracy. Use of moly should extend shot strings at least twofold,
but the need for a thorough cleaning is inevitable. Cleaning should be
aggressive enough to remove all existing moly residue in the bore and provide a
"fresh" bore surface to build on – no moly, no copper.
combination among many moly shooters is
Non-Embedding Bore Cleaning Compound. Nothing seems to get under and loosen
moly quite like Kroil. It penetrates deep to loosen and lift it from the bore
surface. J-B gently removes the remaining moly and attacks caked-on copper
build-up. For routine cleaning of moly-treated barrels, pass a couple patches
of Kroil through the bore followed by several dry patches. Resume with a couple
patches soaked with your favorite copper solvent. Let soak for approximately
ten minutes and proceed with two or three dry patches. Short stoke J-B about
ten times through the bore, followed by two patches of Kroil. Finish by pushing
dry patches through the bore until they appear clean and dry.
rifle will be put in storage for an extended period, run a patch of gun oil
through the bore to prevent rust and corrosion. Before shooting, dry the bore
completely and treat a couple of oversize patches or a bore mop with
Brownells Moly Bore Treatment
. Run it down the bore to burnish the moly into the surface metal.
This should reduce the number of fouling shots to regain optimal barrel
accuracy (1 or 2 shots) and helps prevent corrosion.
