New Hi-Viz Orange Cleaning Rod Guides from Creedmoor Sports

Creedmoor Sports Cleaning Rod Bore Guide Orange PVC Delrin O-Ring Seal

Here’s a new product we like — Creedmoor’s extra-long, fitted Cleaning Rod Guides (aka Bore Guides) that offer a port for adding solvent. We like the distinctive bright orange color. That helps you quickly identify your rifle on crowded cleaning bench.

Why a Rod Guide Is Needed for Proper Bore Cleaning
A good Cleaning Rod Guide ensures that your brushes and jags are centered in your bore, so you don’t get uneven wear in your throat. Moreover the guides protect the action raceways, blocking liquids and debris from entering the trigger group. The port helps you add solvent without making a mess or spilling on a fine stock finish.

The orange Creedmoor Cleaning Rod Guides have some nice features. They are long enough so that you can avoid removing larger optics and include a port to apply solvent. The O-ring at the front provides an additional seal for the chamber. These Rod Guides are designed for specific action types and chamberings for proper alignment. Creedmoor’s Bore guides cost $24.95. That’s quite a bit less than some other vendors’ fitted cleaning rod guides. Current offering are:

Rem 700: .222, .243, 6.5 Creedmoor, .280, .300, .308
Tubb Rifle: 6.5 Creedmoor
Ruger Precision Rifle: 6.5 Creedmoor
AR Platform: AR-10, AR-15

TIP: When using any cleaning rod guide, you should cover the rear of the stock with a towel to prevent any solvent from touching the stock. Solvents can harm find wood, painted, and hydro-dipped finishes.

Your Worst Nightmare: Catastrophic .338 Lapua Magnum Kaboom

Kaboom Manatee Savage .338 LM, Lapua Magnum, catastrophic, explosion, cleaning rod, obstruction
Click to zoom image

We first ran this story a couple years back. We’re republishing it today as a reminder to our readers that safety should be their paramount concern at the range. Avoid distractions and always check your barrel for obstructions before you chamber a round or pull the trigger. A moment of inattention can result in a catastrophic kaboom …

Discharging a .338 Lapua Magnum round with a cleaning rod in the barrel — that’s a recipe for disaster. What happens when a fired .338 caliber bullet and a cleaning rod try to occupy the same place at the same time? Well you get a catastrophic kaboom, with metal pieces flying all over the place, and a shooter very lucky to escape without serious injury. This incident occurred recently in Manatee, Florida, as reported by Sniper’s Hide member Queequeg. We thank SnipersHide.com for granting permission to publish these revealing images in the Daily Bulletin. CLICK HERE for more Kaboom info on the ‘Hide.

This story should serve as a chilling reminder to follow proper safety practices whenever you are at the range. Always check to make sure there is no obstruction in the bore BEFORE loading a live round.

.338 Lapua Magnum + Cleaning Rod + Inattention = Kaboom!

Kaboom at Manatee!
Sniper’s Hide member Queequeg recently published shocking photos of a catastrophic kaboom involving a .338 Lapua Magnum (Savage action). The action was blown off the rifle, shrapnel went through the roof, and the barrel split at the tenon before taking an excursion downrange. The action did crack in the front but the lugs remained engaged so the bolt did not slam to the rear (luckily for the shooter).

Here’s the report: “This happened [January 20, 2014] at the Manatee Gun and Archery Club. Al, Ren and myself were there with a couple other folks. Ren was at bench 12, I was at 13. The fellow at 11 was running a Savage .338 Lapua. He had a very bad day! He damn sure could have killed himself and quite likely Ren as well.”

Kaboom Manatee Savage .338 LM, Lapua Magnum, catastrophic, explosion, cleaning rod, obstruction

Queeqeg added: “After the boom, I heard Ren ask ‘Are you alright’ and then turned to look in time to see the fellow reacting in total shock — literally stunned. Ren and I went over to him and could not see any major injuries. Ren was uninjured as well but had a lot of fiberglass splinters on him. The barrel nut is what I presume punched the two holes in the roof. The shooter is a regular there[.] He had been having a problem with sticky cases though he said he was certain the loads were mild. That’s why he was content to knock the sticky ones out with the rod. He simply forgot to remove the rod after knocking out the last stuck case. You can see what happened next.”

The Important Lesson Here
What did the .338 LM shooter do wrong here? You will say — “Well that’s obvious, he left a cleaning rod in the barrel and then shot a round.” Yes, that was a potentially fatal error. But that was his second mistake — one that occurred only because he made a more fundamental judgment error first.

The FIRST mistake was not acknowledging the problem with his ammo. Had he heeded the warning signs, he would still have a rifle (and an unsoiled pair of trousers). When he first observed that he was having problems with extracting cases, a warning light should have gone off in his head. Presuming his extractor was not broken (and that the chamber was cut properly) he should have been able to extract his brass if he was running safe loads. The lesson here we all need to learn is that if you observe a serious ammo-related issue, it is time to stop shooting. Don’t try to invent work-arounds just to extend your range session, when there are clear signs that something is wrong, very wrong.

New Bore Guide Products from 21st Century Shooting

Chamber-specific bore guide off barrel solvent chamber seal 21st Century Shooting John Perkins

It’s important to use a good-fitting bore-guide whenever you clean your barrel. A good bore-guide will keep solvents out of your action and help your cleaning rods run straight and true.

Not all bore guides are created equal. Some offer a sloppy fit and/or fail to seal your chamber effectively. 21st Century Shooting has changed all that with a new generation of chamber-specific Bore Guides. These have a close fit (with O-rings) to seal your chamber completely. The design is intelligent — these bore guides are long enough to extend well past the end of your scope, while the minimal rod diameter provides sufficient clearance for most combs. Priced at $49.99, these high-tech guide rods are custom crafted to fit many popular chamberings: 220 Swift, 223 Rem, 22-250, 6PPC, 6mmBR, 6 Dasher, 6×47, 6-284, 6mm Shehane, 243 WSM, 6.5×47 Lapua, 6.5-284, 6.5 Shehane, 6.5 WSM, 25-06, 270 WSM, .284 Win, 7mm Shehane, 7mm WSM, 30 BR, 308 Win, 30-06, 300 WSM.

Email John [at] 21stcenturyshooting.com to ask about your application. These chamber-specific guide rods are designed fit actions with BAT bolts or Rem 700-style bolts (Borden, Kelblys, Ruger, Savage).


In addition to the new chamber-specific Guide Rods, 21st Century just released a clever new product for shooters who regularly swap barrels (or who need to clean dismounted barrels). If you have a switch-barrel rig, check out 21st Century’s new Barrel Off Bore Guides. Like the full-length 21st Century bore guides, these are manufactured specifically for your chamber, for a perfect fit. These chamber-specific “Barrel Off” bore guides cost $19.99.

Mystery of the Vibrating Cleaning Rod…

Sierra Bullets Product Development Manager Mark Walker recently acquired a barrel with canted lands. It turns out he needed to modify his bore-cleaning methods. His brushes and patches were not following the rifling… and he was well on his way to ruining his barrel before he figured out the solution. Read about Mark’s interesting (and puzzling) experience. This article first appeared in the Sierra Bullets Blog.

Lessons Learned (The Canted Land Mystery)
by Mark Walker
Sometimes when you have done something so often, you take for granted that it will work for all equipment. In this case, I had used my cleaning process and equipment for years with no problems however a new barrel on a rifle caused me to rethink how I clean.

Last year, the barrel on my mid-range benchrest rifle decided to give up the ghost. After doing some research and asking fellow shooters, I decided to purchase a barrel that had rifling with “canted” lands. The barrel arrived and after looking it over, everything looked great.

Threading and chambering went very well with the barrel indicating in very straight and cutting very smoothly. After torqueing the barrel to the action, I went about loading some ammunition to break the barrel in with. At the range, the barrel shot as good as any I have ever had. Even with loads that were thrown together with no tuning whatsoever.

During the break in, I would clean the barrel after every five shots or so just because that’s what everyone says to do. The barrel cleaned up extremely well, however I noticed that the first patches down a dirty barrel would cause the cleaning rod to vibrate as I pushed them down the tube. That was something that I had never experienced before so I was a little concerned….

After looking at the barrel with a bore scope, everything looked clean and no indication of what might have caused the vibration in the rod. I did notice some surface marks in the bore that traveled perpendicular with the bore. Usually when a barrel is lapped, all marks follow the rifling twist so these marks parallel to the bore where another phenomenon that I had never seen before. The mystery was getting deeper.

After another range session where the barrel shot lights out, I brought it home to clean it as before. The first patches down the barrel again caused the strange vibration in the rod. After stopping and thinking about the vibration and the strange marks in the bore, I checked the bearings in cleaning rod handle to make sure it was spinning freely and everything seemed to be in working order. I then decided to mark the cleaning rod to make sure it was actually turning when it went down the barrel. Bingo — this revealed the problem.

When the first patch went down the barrel and the rod didn’t even attempt to turn, the light bulb went on. The patches and even the bronze brushes were simply skipping over the tops of the rifling and not following the rifling at all. I tried tighter patches and larger brushes, but the only thing that seemed to fix the problem was pushing them down the bore as slowly as possible while watching the mark on the rod to make sure it was turning. Had I continued to clean as I normally do, I surely would have ruined the barrel!

Once I figured out the problem, the barrel shot great and my cleaning process worked just like every other barrel I have ever owned except for having to go slow with the rod. This just goes to show that even though you may have done something a thousand times before, you should always be aware of what your equipment is telling you.

Dewey Mfg. Offers Aluminum Jags

Aluminum jag Dewey

Conventional brass jags work great — except for one thing. They can react to solvents, leaving a blue “false positive” on patches. In recent years, jag-makers have experimented with many different materials in an effort to cure the solvent-reaction problem. Today we have polymer jags, nickel-plated jags, and stainless steel jags. And the latest innovation is the aluminum jag from Dewey.

Aluminum jag DeweyJ. Dewey Mfg. is now producing a series of “Copper Eliminator” jags and brush adapters made from aircraft-grade aluminum with the same hardness as brass. Dewey claims that its new aluminum jags will not become embedded with grit or particles that could harm your bore. At the same time, Dewey’s aluminum jags will not react to ammoniated bore solvents that can turn patches blue green when used with brass jags. Dewey aluminum jags are offered with either male OR female 8/32 threads. The $4.95 aluminum jags and $3.50 brush adapters are offered in a wide variety of calibers. You can order from Dewey Mfg. or Sinclair Int’l.

$10 Rack System Holds Six Cleaning Rods Securely

Fishing Rod Rack Cleaning RodsForum member Nodak7mm has discovered an ideal way to store your rifle cleaning rods in your garage or loading room. Using inexpensive Berkley Fishing Rod Racks, Nodak7mm has secured a half-dozen Dewey rods on the back of a door. You could also mount the racks along a wall or on the side of a storage cabinet. This installation takes up minimal space and the Berkley Racks cost just $9.96 per set at Walmart. If you prefer wood, Wally World also sells a nice lacquered pine 6-rod wall rack for $17.54.

Nodak7mm explains: “I was moving some fishing poles around and ended up with an extra pair of Fishing Rod wall racks. I said to myself, ‘I bet this would hold my Dewey cleaning rods’. I mounted the pair on the inside of a closet door in my man cave and put my cleaning rods in it. It works like a charm and is far cheaper than a specially-made rack that only lets the rods hang. One can even slam the door with the rods mounted and they stay put. This rod rack set is found at almost any decent fishing tackle store, is made by a nationally recognized name and does a great job of holding the cleaning rods securely and safely. Best thing about them is the pair only costs $10 or less.”

Dewey Offers Aluminum Jags and Aluminum-Tipped Rods

For decades shooters have used brass jags attached to brass-tipped cleaning rods. These work effectively. But there is one problem. Many bore solvents will react with the brass metal to give “false positives”. You can get bluish-green patches even when there is no copper fouling in your bore.

To solve this problem DeweyRods.com offers a full line of aluminum jags, aluminum brush adapters, and nylon-coated cleaning rods with aluminum tips. Dewey explains: “Ammonia-based solvents attack copper & brass but also leave your patches a blue-green color so you are never sure if your bore is truly clean of copper. Our aircraft-grade aluminum has the same hardness of brass, it will not embed impurities or harm your bore, and ammonia will not attack it.” As shown below, along with caliber-specific aluminum jags (center), Dewey now offers aluminum thread adaptors (left) and aluminum-shaft brushes (right).

Dewey Aluminum Jags

New Dewey ‘Copper Eliminator’ Cleaning Rods
These new rods have the same nylon coating and handle assembly as Dewey’s standard coated rods, but they feature a chemical-resistant, 8/32 female-threaded, aluminum ferrule. No brush adapters are required. Each rod is supplied with a male-threaded aluminum jag. Dewey charges $39.95 for these rods, but you may find them slightly cheaper at other vendors.

Dewey Copper Eliminator Cleaning Rod

Copper Eliminator Rods are currently offered in two diameters (.22-.26 Cal, or .27+ Cal), and three lengths: 36″, 40″, 44″. Listed rod lengths do NOT include handle assembly. One last note: Dewey cautions users to avoid TM Solution, because this solvent may harm Dewey’s nylon rod-coatings.

RVB Precision Cleaning Rod Bore Guide for 17 HMR Rifles

When Hornady (and CCI) developed the 17 HMR cartridge, they really hit a homerun. And the rifle manufacturers quickly marketed some nice rifles to chamber this 17-cal rimfire round. But unlike .22 LR rifles which, typically, require very little cleaning, 17 HMRs demand frequent bore cleaning to maintain good accuracy. That’s because 17 HMRs shoot copper-jacketed bullets at 2550 fps velocities.

17-Cal Bore Guides — The Challenge
The problem is, it’s hard to find a well-designed, quality bore guide for 17-caliber rimfire rifles. With many 17 HMR (and 17 Mach 2) rifles, you encounter mechanical interference when you try to use a standard bore guide to protect the delicate chamber edge and the bottle neck area of the chamber. A fixed ejector is in the way. On many 17 HMR rifles, this little “shark fin” ejector is right in line with the chamber and is fixed — it doesn’t retract. Therefore the kind of bore guide you might use for centerfire rifles won’t work in 17 HMRs — it will hang up on the ejector.

Polymer bore guides exist for this type of action, but they are typically open-bottom designs that do not enter and seal the chamber. These open-bottom designs don’t protect the delicate chamber edge or the bottleneck area of the chamber, and they also allow some seepage of solvents out of the chamber. That’s why Roy Bertalotto created his RVB Precision Bore Guide for 17 HMR rifles. The 7075 aluminum tube on his Bore Guide is thin enough to pass by the ejector, yet it is extremely rigid. (Photos below.)

Roy explains: “My bore guide is made of 7075 anodized aluminum tubing, which is totally unaffected by any type of cleaning solution. One end is swagged down to fit completely into the chamber of a 17 HMR rifle. This guides your cleaning rod perfectly to the bore without touching the chamber walls or front edge of the chamber. The tight fit of the bore guide in the chamber also stops cleaning solvents from getting into the action, magazine, and trigger housing.” (Editor: Solvent seepage can do damage. We had a 17 Mach 2 rifle that rusted internally because solvents leaked past an open-bottom bore guide.)

Using the RVB 17 HMR Guide – Once the bore guide is in place, slide the supplied aluminum bushing over the tube, and gently push the bushing into the rear of the action. This centers the guide rod in the action to keep the guide rod tube aligned. Once the guide rod and bushing are in place, you can use a 17-caliber cleaning rod* with patches and/or brushes to clean the barrel. Use the rod normally, but make sure your patches are quite small and don’t apply too much pressure as these small-diameter rods can kink if you try to force over-size patches down the bore.

The RVB Precision 17 HMR Bore Guide costs $19.95 plus $5.00 shipping. To order, email Roy Bertalotto via rvb100 [at] comcast.net. Roy will then send you shipping/payment details.

* NOTE: You really do need a dedicated .17-cal cleaning rod for this job. Most other rods are too fat to pass through the barrel. Dewey Mfg. makes a decent 17-caliber cleaning rod that is reasonably stiff and doesn’t kink too readily. It is available sizes from 7″ to 36″, either bare stainless or with a nylon coating. We prefer the nylon-coated version, in either 26″ or 36″ lengths, depending on barrel length.

Dewey 17 cal caliber bore guide

If you have a high comb on your rifle, you may need extra length to avoid interference with the rod handle. Use this formula to determine correct rod length: Length of barrel + action or breech rod guide length + 2-3″ clearance + high comb if applicable = total rod length needed.

There are other quality 17-cal cleaning rods, but we’ve used the Dewey and it functioned well. The nylon coating cleaned easily and was gentle on the throat and crown. You should clean the coating before and after each use to ensure it does not embed grit or other contaminants.
