Barrel Care and Maintenance — Expert Advice

Shooting Sports Lohman Barrel

Ask 10 shooters about barrel cleaning and you’ll get 10 different opinions. This reflects that fact that different fouling problems demand different solutions. For example, solvents that work well for copper may not be the best for hard carbon (and vice-versa). To come up with the right solution, first you must understand the nature of the fouling in your barrel.

Chip Lohman, former Editor of Shooting Sports USA Magazine, has authored an excellent article on barrel maintenance and cleaning. Chip’s article, Let the BARREL Tell You — Match Barrel Care, can be found in the Shooting Sports USA digital archives. In this article, Chip shares the knowledge of a dozen experts including barrel-makers Frank Green (Bartlein Barrels), John Krieger (Krieger Barrels), and Tim North (Broughton Barrels).

The debate about the proper care of a match barrel is a hot one, spiked with folklore and old wives’ tales, Lohman said. He and his staff set out to set the record straight: “We tried to interject some science into the discussion of cleaning a match barrel,” he explained. In his article, Lohman writes:

Why worry about a little barrel fouling when the throat is subjected to a brutal 5,600° F volcano at 55,000 PSI? To investigate these and other questions about taking care of a match barrel, we spoke with a dozen experts and share their knowledge in this first of a series of articles.

After listening to folks who shoot, build barrels or manufacture cleaning solvents for a living, we concluded that even the experts each have their own unique recommendations on how to care for a match barrel. But they all agree on one thing — the gun will tell you what it likes best. Because the life expectancy of a match barrel is about 1,500 to 2,500 rounds, the objectives of cleaning one should include: preserve accuracy, slow the erosion, and remove fouling — all without damaging the gun. This article doesn’t claim that one cleaning method is better than the next. Rather, we set out to interject a little science into the discussion and to share some lessons learned from experts in the field.

BoreSmith Patents Triangular Patches and Dual-Diameter Brushes

The U.S. Patent Office has awarded BoreSmith utility patents for two unique gun cleaning products. Patents were issued for BoreSmith’s triangular Pyramid Patch™ as well as BoreSmith’s dual-diameter JagBrush™. Both products were designed by Shane Smith, a mathematician/physicist who used his scientific and firearms knowledge to create innovative bore-cleaning products that may well work better than conventional patches and brushes.

BoreSmith’s clever Triangle Patch™ (aka Pyramid Patch) presents more cleaning surface area to the bore wall than does a conventional square or round patch (of equivalent size). At the same time, the unique geometry makes Triangle Patches much less likely to jam in the barrel. This is because the notches in the sides of the triangle allow the patch to sit more uniformly on the jag (without bunching up). The Triangle patch can be used with a standard jag but works best when paired with BoreSmith’s patented dual-diameter JagBrush. Order Triangle Patches HERE.

Rigel BoreSmith Brush Patch Jag Pyramid Triangle patches

Triangle Patch Function and Geometry Explained (See 1:18 time-mark):

NOTE: Despite what you may see in this video, you should insert brushes and patches from the chamber end first, using a well-fitting cleaning rod bore guide. With bolt-action rifles, NEVER insert a cleaning rod (with brush or jag) in through the muzzle. This may damage the delicate crown of your barrel.

Patent Awarded to Dual-Diameter JagBrush
The JagBrush is like a standard bore brush but has two different diameters on the bristle section. Bristles in the front are smaller, while the rear bristles are similar length to a standard bore brush. When a patch is pushed through the bore using a JagBrush, the smaller bristles will grab the patch, leaving the longer bristles exposed and creating a dual-­action wiping + brushing system. JagBrushes are offered in a wide variety of calibers, in both bronze and nylon versions.

Shane Smith, CEO of BoreSmith, was pleased that his designs have been awarded two important patents: “I created these tools to allow the user to get their firearms cleaner, faster, and without causing unnecessary damage in the process. At BoreSmith, we strive to develop and produce superior cleaning tools that help firearm owners protect their investments.” For more info, visit BoreSmith at RigelProducts.com.

Gear Review: Range Box with Gun Cradle from MTM

One of our Forum members asked us the question: “Does anybody make a good range box with cradles for cleaning at the bench?” The answer is yes — the MTM model RBMC Range Box offers slide-in plastic cradles that provide a reasonably sturdy platform for a quick clean when you’re done shooting. The RBMC box also offers plenty of storage for jags, brushes, solvents, ammo boxes and other miscellaneous gear you need for the range.

Among the many range boxes available, the MTM model RBMC Range Box leads the pack in terms of versatility. It is rugged, it has plenty of storage space, plus it doubles as a handy cleaning station. This Editor has used the MTM Range Box to clean rifles and as a “range expedient” rifle holder when adjusting scopes and tensioning action screws. It’s a good product that does the job and stands up to rough handling.

MTM Range Box

Fitted Cleaning Cradles
The key feature setting MTM’s RBMC apart from most range boxes is the rubber-coated cradle system. Wide enough to fit a 3″-wide fore-arm, the cradles slide into vertical slots on either end of the box. This allows your range box to serve as a stable maintenance station. The RBMC is really pretty stable in this role, and the cradles won’t mark your stock. The cradles even feature slots on each side to hold your cleaning rods when not in use. The MTM Range Box is secure enough to stay in place when you’re brushing the barrel. However, if you’re working on a carpeted bench top, you may want to keep one hand on the box when running a cleaning rod through the bore, just to ensure the box doesn’t slide.

MTM Range Box

Versatile Upper Tray with Dividers
The MTM Range Box has two major components — the box base (with cradles), and a large upper tray with hinged top and carry handle. This large upper tray clamps securely to the bottom unit for transport. The top tray has a long section that holds cleaning rod guides, long brushes, grease syringes and the like. There are two, clear-plastic fitted divider trays. These will hold your patches and jags, plus comparators, ring wrenches, and other small tools.

MTM Range BoxWhat Might Be Improved
Though we really like the MTM Range Box, it’s not perfect. First, we wish the box was a bit deeper, to have added carrying capacity. The dimensions of the MTM Range Box are: 25″ long x 11.5″ wide x 8.75″ high. We’d like to see it 12″ high/deep to allow larger solvent bottles to stand upright and to provide more space to carry tools and shooting muffs. However, it is deep enough to hold the large 100-round MTM cartridge boxes that are popular with many shooters (see photo at left).

The cradles are very nicely designed, and will hold your rifle securely without marking the stock. However, we’ve found that sometimes the rear cradle grips the gun so well that the cradle slides out as you lift the gun up. This is not a big deal, but it does demand a little extra attention when you’ve finished cleaning. We really like the twin clear plastic dividers that fit into the large removable top-tray, but we wish the dividers had individual hinged tops. This would keep patches and small parts more secure.

The MTM Range Box costs about $46.00 at most vendors. The MTM Shooting Range Box RBMC-11 (green version) is on sale now for $35.68 at Amazon.com, with FREE shipping. The red RBMC-30 version (shown below) costs slightly more, and may currently be hard to find.

Ultrasonic Case Cleaning — What’s the Optimal Dwell Time?

If you’ve read our feature story on Ultrasonic Cleaning by Jason Baney, you’ve seen the remarkable results that can be achieved with this method. Ultrasonic cleaning has many advantages over traditional tumbling methods of case cleaning. There is no dust or media residue to remove from the brass, and when done right, the cases come out clean and shiney, inside and out, even the primer pockets.

In its Benchtalk Archives, Brownell’s has an excellent article discussing Ultrasonic Case Cleaning. Brownell’s staff compares results, with measured dwell times from 5 to 75 minutes, using both Mpro-7 and HCS 200 cleaning solutions. Tests are performed with once-fired and 5X-fired Tactical 20 (Tac20) cases, as well as once-fired .260 Rem Cases. The article also compares the results from ultrasonic cleaning vs. tumbling in walnut media. Below are Brownell’s results for Tac20 cases with the HCS 200 (non-acidic solution). Go to Brownell’s article for MPro7 results and Rem 260 results.

HCS 200 Cleaning Solution Test
Procedure — Solution was de-gassed for 15 minutes, then 63 Tac20 cases were placed in a single layer, in stainless steel mesh basket. The temperature of the starting solution was 102° F. When the cases were removed the temperature was 110° F.

Once-Fired Tactical Twenty Cases (HCS 200) — Observations
5 minutes: The exterior of the cases are not significantly brighter/cleaner. The primer pockets and case interiors are still dirty.
10 minutes: Exterior of the cases are brighter. 70% of the cases show some degree of cleaning of the primer pockets. Little difference seen inside the case, but case mouths are cleaner.
15 minutes: Case brightness is about the same. Still only 70% of the primer pockets are clean, but a larger portion of each is cleaner. A Q-tip swabbed inside the cases shows that carbon/powder residues are loosening up.
20 minutes: Case exteriors are brightening up. 80-85% of the primer pockets are about 90% clean. The insides of the cases and case mouths are cleaner.
25 minutes: Cases are brighter/cleaner than even new brass. 80-85% of the cases have almost completely clean primer pockets. The inside of the cases are 80-90% clean.
30 minutes: The insides of the cases and case mouths appear to be completely clean. 87% of the primer pockets are virtually 100% clean. 13% of the cases had stubborn primer pocket residue that could not be completely removed.
60 minutes: Eight cases (13%) were placed in the tank for another 30 minutes to try to remove the remaining residue in their primer pockets. Six out of the eight cases were completely clean.

Five-Times Fired Tac20 Cases — Observations
30 minutes: Based on the above observations, I didn’t begin to observe these 5-time fired cases until after 30 minutes: The exterior cases are bright/clean. Brighter than new cases. The primer pockets on 75% of the cases are 75% clean. The remaining cases had primer pockets that were only 25% clean. The inside of the cases appear to be clean.
65 minutes: 25% of the primer pockets were 95% clean, 25% of the primer pockets were 90% clean, 25% of the primer pockets were 85% clean; and 25% were 80% clean.
75 minutes: 75% of the primer pockets were 90% clean.

How Does Ultrasonic Cleaning Work?
The Brownell’s article explains: “Ultrasonic cleaning uses high-frequency sound waves (generally between 20-80 kHz) to remove a variety of contaminants from objects immersed in a liquid. The result of these high-frequency sound waves is a process called cavitation. These high frequency bursts of ultrasonic energy produce a three-dimensional wave of alternating positive and negative pressure areas as the sound wave passes through the solution. During negative pressure, microscopic cavitation bubbles form and will continue to grown until they reach resonant size. As the positive sound wave passes, the pressure rises rapidly and implodes these tiny bubbles. Before these minuscule bubbles implode they store a tremendous amount of energy. These bubbles can be as hot as 10,000 degrees and have as much as 50,000 lbs per square inch of pressure. This sounds alarming, but you have to remember that these bubbles are microscopic in nature and pose no harm to anything, unless you are a carbon /powder residue deposit on a cartridge case!

When this cavitation bubble implodes near your brass case, it transforms the bubble into a jet about 1/10th of its size. This jet of energy can travel as fast as 400 km/hour. At 43 kHz, as is the frequency for our L & R HCS 200 ultrasonic cleaner, this is happening 43,000 times per second. This micro-burst of extreme energy is responsible for removing contaminants from the surface of your cartridge brass. Ultrasonic cleaning can reach into crevices and inaccessible areas and remove surface debris that can’t be cleaned by any other process.”

New Hot Tub™ Ultra-Sonic Cleaning Machine from Hornady

Hornady has announced new products for 2013. These include a number of new bullets, along with new loaded rifle, pistol, and shotgun ammunition. Perhaps most interesting for precision reloaders is Hornady’s new jumbo Ultrasonic Cleaning machine (MSRP $658.33). Featuring a 9-liter capacity, the new Hornady Hot Tub™ is long enough to accommodate and clean a 16-inch AR-15 upper. Along with its large capacity, the Hot Tub has many advanced features.

Hornady Hot Tub Cleaner

New Large-Size Ultra-Sonic Cleaning Machine — the Hot Tub™
For 2013, Hornady will be offering a new, jumbo-sized ultra-sonic cleaning machine that can handle big parts and accessories. In addition to having four (4) transducers, there is also a heating element that enhances cleaning action. Hornady says that “the microjet action of the Hornady® Hot Tub™ removes carbon residue and other debris from cartridge cases, gun parts and other metal equipment.” We know that ultra-sonic cleaning works well on cartridge cases, provided you have a good machine, a suitable solution, and run the machine for an appropriate time.

Hornady Hot Tub Cleaner

The new Hot Tub is well-equipped out of the box. One 1.7 quart inner tank comes with the unit and can be used in the main tank for cleaning multiple smaller batches or to use separate solutions at the same time. Additional inner tanks can be purchased separately. Hanging cords have been integrated into the design to allow large objects to take full advantage of the ultrasonic energy. Additionally, the Hot Tub® features integrated drain pans in the lids, a small parts basket, a degas function and five (5) temperature settings from 100-140°F.

STOKBOOT Shields Stock from Solvents and Scratches

Benchrest shooter Bill Gammon offers a nice product that helps prevent solvents and oils from marring the finish of a fine wood stock, or a painted fiberglass stock. The STOKBOOT also prevents solvents from softening the bedding, while guarding against nicks and scratches. Gammon’s STOKBOOT fits over the rifle stock during cleaning of the barrel. The quilt on the outside soaks up the solvent before it reaches the stock and holds it until it evaporates. A twin layer of vinyl on the inside stops any solvents from getting through, but Gammon cautions that you should not leave the STOKBOOT on overnight, because solvents could soak through. The basic colors are Red, Wine, Black, Blue, and Green. Typical retail price is about $17.00.

Gammon Stokboot

Gammon explains how he came up with the STOKBOOT: “My wife Barbara and I started this business in 1992 as a means to support a very expensive sport, namely Bench Rest. My wife had been in the sewing business for many years. Her experience included sewing, layout, cutting, and management, so it was only logical that the next step was opening our own business. I had complained about having to use a rag over my stock to prevent solvents that I was using from ruining the paint job on the stock, and also seeping into the bedding area and softening up the bedding. So between her expertise in the sewing world and my practical knowledge, we came up with our first STOKBOOT.”

Gammon Stokboot

Gammon sells wholesale only. His STOKBOOTs are available through popular retail vendors including: Accuracy Arms, Borden Rifles, Bruno Shooters Supply, Russ Haydon’s Shooters’ Supply, Sinclair International. European dealers are: Reloading Solutions (UK), and Heinz Henke (Germany).

T.K. Nollan’s Barrel Saver Cleaning Rod Guide

Smart shooters know the importance of using a quality cleaning rod bore guide when cleaning barrels. The rod guide helps center the rod in the bore, preventing uneven wear on the rifling. Good bore guides also seal off the chamber to prevent solvents and gunk from flowing back into the bolt raceway and trigger housing. While most bore guides are “better than nothing”, the best designs are custom-sized to the chamber and also have a very tight clearance around the rod shaft. This prevents the rod from bowing and from dragging on the critical throat area of your rifle. We use Lucas Rod Guides for many of our rifles. The Lucas two-part design, with a caliber-specific insert, provides a tight fit for the rod.

T.K. Nollan’s Barrel Saver System
While many readers may have seen or used Lucas Rod Guides, T.K. Nollan makes another very high-quality cleaning rod guide that is favored by top benchrest shooters such as Tony Boyer, Dwight Scott, and Dick Wright. If, like many short-range Benchresters, you do a lot of barrel brushing, it may be worth investing in the $135.00 Barrel Saver.

T.K. Nollan Barrel Saver

T.K. Nollan’s patent-pending Barrel Saver is a precision-machined system designed to provide maximum protection during barrel cleaning. The Barrel Saver features a double O-ring “fail-safe” seal, and a stainless steel outer tube with straightness held to within .001″. To help ensure optimal alignment, a bushing, custom-sized for your action, precisely centers the outer tube in your action. Models are offered for Hall, Stolle, Grizzly, Farley, Remington, RFD, Nesika Bay, Borden, BAT, Viper and similar 2-lug actions.

Each Nollan Barrel Saver comes with two (2) metal guide tubes, one for brushes and the other for jags. As you can see in the slide show below, these brush/jag tubes run INSIDE the larger diameter guide which slides into the action and chamber. This “tube-within-tube” design, combined with the 0-ring for the chamber, ensures that the cleaning rod stays precisely centered, even if you brush fairly aggressively. While we strongly advocate bore-brushing only in the outward direction, we know some shooters prefer to brush back and forth. If you are a “back and forth” cleaner, you NEED a product like the T.K. Nollan Barrel Saver.

T.K. Nollan Barrel Savers start at $135.00 plus $9.00 shipping for PPC-type chamberings. Custom sizes cost $150.00 plus $9.00 shipping. Each Barrel Saver kit comes complete with two Rod Guide Tubes and spare O-rings. For more info, visit the Barrel Saver website, or contact T.K. Nollan at this address:
