New WiFi and Rigid Teslong Borescopes Reviewed

Teslong Borescopes Update — WiFi and Rigid Rod Versions
Product Report by F-Class John
Not more than a few months after the Teslong corded borescope hit the market to massive applause they’ve released a cordless WiFi-enabled corded version as well as a rigid rod model — two new models with important new features/functionality. When I originally reviewed the Teslong borescope I was blown away with the value, clarity, and ease of use. SEE Review HERE. That original Teslong really was a game changer in the borescope market. The large number of forum threads springing up since the Teslong release shows that that digital borescopes have finally found a large and enthusiastic customer base.

IMPORTANT: Guys — Watch the Videos!!! John does a great job showing the set-up and use of these Borescopes. You really need to WATCH THE VIDEOS! They show much more than we can illustrate with still images.

NOTE: The WiFi Teslong Borescope can also be ordered for $74.99 from the Teslong Webstore.

WiFi Teslong Works with SmartPhones and Tablets

Despite all the love people have shown for the original, plug-in Teslong borescope, one common complaint was that it could not be used with smartphones or small tablets. With that in mind, Teslong surprised the market with the release of a cordless WiFi version that works with just about any device that has a WiFi connection. The new WiFi unit, which is in very high demand, costs around $75, just $25 more than the original plug-in version. NOTE –YES this WiFi unit DOES work with both iOS (Apple) and Android smartphones and tablets. However, you may wish to try a couple different Apps.

To use the WiFi Teslong, simply download Teslong’s viewer App, turn the unit on and connect to the Teslong WiFi in your device settings. While it does take a couple steps to connect each time, you are rewarded with a cordless version that can be used at home or the range equally well. Watch the video and you can see how the Wifi unit is set up and how it is used to inspect both a barrel and a sizing die. Do watch the video — it explains all. Along with live video feed, the WiFi control handle has a button to record still images.

Important — some guys had initial problems getting the WiFi image to display on their smartphones but that was normally just a software configuration issue. If you are patient, and follow the instructions, you should be fine. Some older guys had to enlist the aid of a 10-year-old grandkid. Note, as of 1/29/2020, the WiFi Version is temporarily out of stock on Amazon, but it can be ordered for $74.99 from the Teslong Webstore.

New Teslong Rigid Rod Borescope

Along with the WiFi version, Teslong has also released a borescope with the lens mounted on the end of a rigid metal shaft — a configuration similar to classic optical borescopes such as the Hawkeye. This new “shafty” Teslong has the same electro-optical sensors, connectors, and adjustable light as the original Teslong. However, this new rigid rig now uses a solid rod instead of a flexible cable. Having a solid rod makes using the unit much easier since you’re not fighting the cable. The rod also makes rotating the unit inside the bore more intuitive as it lacks the cable spring back of the flexible version.

Located on the borescope is an inch scale allowing the user to easily to measure how far into the bore they’ve gone for easy identification of any issues later. The whole unit comes in a nice heavy-duty cardboard tube that makes it easy to store and I can see it lasting as long as the unit itself.

Why choose the rigid Teslong? Importantly, the lack of a tethered cord allows you to rotate the unit more easily inside the barrel. Compared to the original corded Teslong, I did find that running the rigid borescope down the barrel without the mirror provided a larger view. That may be beneficial to some users. Overall, the optical clarity and definition remain excellent — certainly on par with the original unit.

General Teslong Borescope User Tips
The new Wifi and Rigid Teslong borescope share some basic features with the original plug-in, corded Teslong. All three devices feature a mirror on the end that screws on and has a jam nut to keep it in place and can be adjusted for focal length based on the caliber and they’re now including several extras in case of damage or loss. While they’ve always been good about replacing them free of charge there is a wait time, so the inclusion of extras is a nice bonus.

SUMMARY — Both WiFi and Rigid Teslong Borescopes Perform Well, Are Great Values
Overall these two new units are great additions to Teslong’s lineup giving users two great units to choose from. While most folks may gravitate to the WiFi version, I think there’s room for all three models (WiFi, Corded Plug-in, Rigid Plug-in).

Many people may find the corded or rigid versions more practical for around the house where they don’t necessarily need the cordless version and don’t want to worry about keeping it charged all the time. For any range use or out of town matches the WiFi with its smaller footprint and ability to work with any electronic device will probably make more sense and will help justify the additional cost. In the end, the amazing thing is that no matter which version you choose you’ll have a great borescope that will help improve your shooting.

Beyond the Borescope — BEMIS Laser Barrel Inspection Machine

Chesapeake Testing BEMIS laser bore scanner barrel inspection machine
Here is the BEMIS-SC (Small Caliber) Barrel Inspection Machine. This laser system captures thousands of precise data points over the full length of a .22-.50 caliber bore

Do you think your digital borescope is a state-of-the-art bore inspection device? Well think again. There is now something way more advanced than any optical or electro-optical borescope. A new laser-equipped scanning device can map the entire interior surface of a barrel bore. With this new technology you can now examine every land and every groove, millimeter by millimeter, from the chamber to the tip of the muzzle. The most minute flaw in a barrel can now be revealed.

Chesapeake Testing BEMIS laser bore scanner barrel inspection machineThe new device is called the BEMIS-SC™ (for Barrel Inspection Machine Small Caliber). Operated by NTS Chesapeake Testing, BEMIS-SC performs non-destructive laser-based mapping of gun bores. The BEMIS-SC currently works with .22 caliber to .50 caliber (5.56 – 12.7 mm) barrels. The BEMIS captures thousands of highly accurate data points over the full length of a barrel. The inspection can be completed in mere minutes, with scan results displayed in graphical, tabular, and 3D visual formats. Here is a barrel cross-section, as scanned by the BEMIS-SC:

Chesapeake Testing BEMIS laser bore scanner barrel inspection machine

Until the 1980s, gun tube inspection had to be conducted by hand using a manual “star” gauge, a process that would take hours and provide minimal data. Electronic gauges were eventually developed along with the video bore scope, but these systems were still limited to very few, low-resolution data points. That has all changed with the BEMIS™, a huge leap forward in technology that is capable of rapidly capturing thousands of precise data points.

Chesapeake Testing commenced BEMIS-SC barrel inspection services in September 2014. Testing is performed in Chesapeake’s commercial barrel inspection laboratory, located in Belcamp, MD, minutes from the U.S. Army Aberdeen Proving Ground. While testing is currently limited to .22 to .50 caliber barrels, Chesapeake Testing will accommodate both smaller and larger calibers in the future.

“We have always focused on building our company around very unique technologies. BEMIS™ has changed the industry in regards to the inspection of weapon systems. We are excited to be an exclusive partner with LTC in this industry and look forward to contributing to the future of this technology,” says Jim Foulk, founder and president of Chesapeake Testing.

Heat Build-Up and Firing Rate Can Kill a Barrel Prematurely

barrel life test rapid fire cooling

Can sustained rapid-fire shooting with no cool-down period wear out a quality barrel more quickly? The answer is “Yes” according to Forum member LCazador, who did an interesting comparison test with two .243 Winchester barrels. He started off with two, identical, match-grade HV taper stainless barrels. Both were NEW at the start of testing, and LCazador shot the same load through each: 95gr match bullets with 38 grains of Hodgdon Varget. After giving both barrels the same, gentle 20-round break-in, 300 rounds were then fired through each barrel — in very different ways. Barrel condition and wear were monitored with a borescope.

Barrel One — Slow Fire, Cool Down Periods, Cleaning Every 50 Rounds
At the end of the 300-round test, Barrel One looked brand new. There was none of the severe fire cracking found in Barrel Two. This barrel was shot no more than 10 times without a cool down and firing was done at a much slower pace. Cleaning for this barrel was done every 50 shots.

Barrel Two — Fast Firing, No Waiting, Cleaning Every 100 Rounds
The second barrel, which received hard use and minimal cleaning, was severely damaged with severe fire cracking at the leade and throat. As a result, the barrel had to be re-chambered. This barrel was shot 100 rounds at time without cleaning and was shot up to 20 times in succession without a cool down.

LESSON LEARNED — Heat Kills Barrel Life
Don’t let your barrel get too hot, and keep it clean. One afternoon can ruin a barrel!

Hawkeye Borescope imageMonitoring Barrel Wear with Borescope
Some folks worry too much about what their borescopes reveal — many barrels do not have to be “squeaky clean” to perform well. In fact some barrels run better after ten or more fouling shots. However, a borescope can be very helpful when your barrel starts losing accuracy for no apparent reason. Forum member FdShuster writes:

“A borescope is a positive way of backing up your suspicions when the rifle starts to throw an occasional (soon followed by more frequent) wild shot. Using the scope is also an excellent way to determine that the cause is barrel wear and not simply a need for a concentrated cleaning session to remove built up copper and more importantly, carbon fouling.

I’ve had a few barrels that gave every indication of being shot out. But I ‘scoped them out and found the cause to be nothing more than requiring a good cleaning. They then returned to their usual performance. There’s no guessing involved when you are able to get ‘up close and personal’ using the scope. The borescope also provides an excellent view of the all-important condition of the crown. My borescope is one of the most valuable investments I’ve ever made.”

Borescopes & Borecams — What They Reveal Inside Your Barrel

Hawkeye borescope POV lens
Lyman BoreCam borescope digital endoscope

Hawkeye borescope POV lensEvery serious shooter shoot have a borescope — whether an classic optical unit, or the newer type with digital camera and viewing screen, such as the Lyman Borecam.

A quality borescope or Borecam lets you look inside your barrel to check the effectiveness of your cleaning and determine how the barrel is wearing. To learn how a borescope can help you diagnose barrel issues, you should read a Rifle Shooter magazine feature story, What the Eye Can See.

In this article, writer Terry Wieland explains how to inspect for defects in new barrels, how to recognize different kinds of fouling (in both barrels and brass), and how to spot throat erosion in its early stages. Terry uses a Gradient Lens HawkEye BoreScope. The current generation of HawkEyes can be attached to a still or video camera to record digital images of your bore. The most interesting part of the article is on the second page. There, author Wieland provides photos of various types of internal flaws that can appear in barrels. This will help you spot pitting, excessive land wear, rust damage, and damage from corrosive primers.

Wieland notes that BoreScopes aren’t just for barrels: “The borescope has other uses as well. It can be used to examine the interior of a cartridge case to look for the beginnings of a case separation or to examine the interior of a loading die that is giving you trouble. When you consider the number of tubular objects that play such an important role in rifle shooting, it is a wonder we were ever able to function without such a method of studying bores.”

This Gradient Lens video shows how to correctly borescope your barrel:

Bargain-Finder 183: AccurateShooter’s Deals of the Week

Accurateshooter Bargain Finder Deals of Week

At the request of our readers, we provide select “Deals of the Week”. Every Monday morning we offer our Best Bargain selections. Here are some of the best deals on firearms, hardware, reloading components, optics, and shooting accessories. Be aware that sale prices are subject to change, and once clearance inventory is sold, it’s gone for good. You snooze you lose.

1. Graf’s and Creedmoor Sports — Peterson Brass

peterson brass

Peterson Brass is quickly becoming a leading cartridge brass producer for good reason. Peterson offers good quality, long-lasting, American-made brass at very competitive prices. For PRS and other disciplines not requiring one-hole accuracy, Peterson brass may be up to the task. Plus some Peterson brass varieties come pre-sorted by weight and length — that saves time! Along with popular cartridge types, such as 6.5 Creedmoor, 6mmBR, and .308 Win, Peterson offers brass for cartridges with fewer brass options — such as 6XC, .300 Norma Magnum, .375 CheyTac, .408 CheyTac, and others. Peterson’s CheyTac brass has found favor with the ELR crowd. Purchase Peterson Brass from Graf and Sons or Creedmoor Sports. Both vendors offer competitive pricing and great customer service.

2. Amazon — Digital Flex-Cord WiFi BoreScope, $32.99

digital borescope

borescope endoscope wireless digital camera wifi wirelessHave you wanted a high-end optical borescope but couldn’t bear the price (as much as a complete rifle)? Here’s an incredibly affordable alternative. For under forty bucks you can get a high-tech, digital endoscope that sends video, via WiFi, to your Android or iOS smartphone, or other mobile device.

This is a great value. Pick up one of these digital borescopes for only $32.99. These digital endoscopes feature a 5.5mm-diameter camera head so you can scope just about any barrel from .22 caliber up to .50 caliber. NOTE: A buyer reports the mirror extension increases the end diameter to 6.5mm so that limits 90deg views with smaller diameter barrels. The unit sends the image wirelessly to your phone, and charges with a USB connection. Watch in real time or record for future viewing. Along with bore-inspection chores, you can use this versatile gadget to find parts you drop behind the bench or even inspect your vehicles.

3. Bruno’s — Berger 7mm 184gr Hybrids, $45.70/100

berger 184gr hybrids

If you’re a competitive shooter, you know how important it is to get all the components you need for the entire match season or risk running short at the worst time. Topping the “must have” list of many F-Class competitors are the record-setting Berger 7mm/.284 184gr Hybrid Target bullets. Brunos Shooters Supply now has these Berger 7mm 184gr Hybrid Target Bullets in stock. These will, no doubt, become very hard-to-find later this year. So don’t miss out while they’re available or you’ll be sorry later. Bruno’s HERE: Berger 7mm Hybrids $47.30/100.

4. March Optics — All Scopes on Sale

March Optics Sale

Every time we head to a match we see more and more March Optics on the line and there’s a good reason why. March offers some amazing scopes, offering incredible clarity, sharpness, and magnification ranges you won’t find on other scope series. If you’re looking to upgrade to a serious, competition-grade optic, here is your chance to grab a March scope at up to 30% off.

5. Amazon — Howard Leight Impact Electronic Muffs, $35.99

Howard Leight Ear Muffs

All firearms enthusiasts need to protect their hearing. Even a single shot can damage your hearing. We like to use double coverage, with plugs under electronic muffs. This provides outstanding hearing protection, AND you can still hear range commands. The very popular Howard Leight Impact Sport ear muffs are now on sale for just $35.99. With that attractive price, there’s no excuse for not having ear protection in your range bag. These Impact Sport muffs are without question the most commonly-used electronic muffs because they offer great performance for the price.

6. Natchez — Lyman Auto-Advance Target System, $109.49

lyman auto advance target

Target cameras and electronic targets are cool but of course that all comes with high prices and technical hassles. Now there’s a smart, affordable solution that lets you quickly change your targets without moving from your firing position. The Lyman Auto Advance Target System holds multiple targets on a motor-advanced roll. With the push of a button, you can command new targets to roll up into view. The wireless controller lets you place the target frame up to 200 yards away. Lyman sells a variety of target rolls. Each has enough targets to keep you shooting all weekend without changing. We really like this unit for rimfire shooting. The unit is easy to set-up and adjust for different heights.

7. Midsouth — Assorted Hornady Gauge and Comparator Tools

hornady comparator tools

Bullet seating depth is a key variable in precision reloading. For best accuracy you really need to know LENGTH to LANDS, i.e. the point at which your bullet will first touch the rifling in the barrel. Adjustment of cartridge base-to-ogive length (from “jam” to “jump”) is a critical method of optimizing rifle accuracy. With some barrels, cartridge types, and bullets it may be best to seat into the lands. With other barrels and bullets you’ll want to “jump” the bullets 20, 30, or even 40 thousandths (or more). To determine your length to lands with repeatable precision, we recommend the Hornady Comparator tools. Grab the straight OAL gauge and either the basic set with 6 inserts or the full set with 14 inserts and start collecting real data about your chambers. You can also grab an extra comparator body on sale.

8. Amazon — Pop Packs Color Burst Targets, $28.91

pop sacks bursting targets

Do you love reactive targets but don’t live in an area that allows exploding targets? These colorful Pop Packs liquid-filled splash targets offer a safe, cost-effective and fun alternative to exploding targets. Now you can grab 48 Pop Packs bursting targets for just $28.91. There are also 12-packs, 24-packs, and even 96-packs of these bursting Pop Packs targets. The more you buy the lower the cost per sack. Keep in mind these make a messy splatter and should not be used without permission of your range owner or managers.

9. Palmetto State Armory — Multi-Brand Scope Savings

scope sale

If you’ve been looking for a feature-laden riflescope for your next gun, check out Palmetto State Armory (PSA). This vendor has some lesser-known brands, such as Eotech, at great savings.

The Lyman Borecam comes complete with everything you need. Shown in photo are:

1. Borecam Wand (includes handle, rod, mirror, and digital lens/camera) with length indication scale. An inch scale runs the full length of the rod. That tells you where the lens is positioned inside the bore. Note the wand scale marks when recording screen captures.
2. Borecam Digital Display. The 600×480 display can record stills with included 128MB SD Card. A USB SD Card adapter is included.
3. Borecam Mirror Protector and cleaning kit.
4. AC Power Adapter (not shown, international plug adapters included).

UltimateReloader offers three key tips for the Lyman Borecam:

— First, before you start, make sure the mirror is clear and free of dirt, lint, or solvents.
— Use the Up and Down Arrows to adjust the illumination to suit your barrel.
— Experiment with how close you hold the mirror to the wall of the bore. This affects both brightness and focus.

YouTube Viewer Comments on UltimateReloader Lyman Borecam Video:

“Great review, Gavin. Your video capture of the display looks better than what they show in Lyman’s own product video.”

“Price is getting low enough to think I need one on the short ‘To Buy’ list. Have some milsurp rifles with horrid bores that should be very interesting to view. Don’t waste $$ on those $20 things on Amazon, I did and thoroughly wasted my money.”

Borescope Basics — How to Diagnose Problems in Your Barrels

Hawkeye borescope POV lens

Hawkeye borescope POV lensA quality borescope is a pricey tool, but once you get to use one, it’s hard to imagine how you ever did without it. To learn how a borescope can help you diagnose barrel issues, you should read a Rifle Shooter magazine feature story, What the Eye Can See.

In this article, writer Terry Wieland explains how to inspect for defects in new barrels, how to recognize different kinds of fouling (in both barrels and brass), and how to spot throat erosion in its early stages. Terry uses a Gradient Lens HawkEye BoreScope. The current generation of HawkEyes can be attached to a still or video camera to record digital images of your bore. The most interesting part of the article is on the second page. There, author Wieland provides photos of various types of internal flaws that can appear in barrels. This will help you spot pitting, excessive land wear, rust damage, and damage from corrosive primers.

Wieland notes that BoreScopes aren’t just for barrels: “The borescope has other uses as well. It can be used to examine the interior of a cartridge case to look for the beginnings of a case separation or to examine the interior of a loading die that is giving you trouble. When you consider the number of tubular objects that play such an important role in rifle shooting, it is a wonder we were ever able to function without such a method of studying bores.”

Grafs.com Has Lyman Borecam in Stock Today for $259.99

AccurateShooter Deals of Week Lyman Grafs.com Borecam Digital Borescope.

The Lyman Borecam is an electro-optical borescope with a digital display. You can record “stills” on a SD card. This is one of the hottest products on the market right now — so hot that it has been sold out for weeks. But Grafs.com just got a shipment of Borecams (item LY04055), and the price is more than competitive. Right now Grafs has the Borecam in stock for $259.99 with free shipping (after a single $7.95 handling fee). That price is $40.00 less than some other online vendors are charging.

This is a good product. Guys who purchased the Lyman Borecam are very happy. If you don’t have one yet, now may be the time to “pull the trigger”. After this article goes live, we expect Grafs.com to sell out quickly. Graf’s inventory may be gone by end-of-day today.

Our British friend Vince Bottomley did an extensive review, giving the Lyman Borecam high praise. Vince says serious shooters should definitely acquire one of these tools: “In my opinion, this product is one of the very best to come along in recent years and I predict that the demand for these [Lyman Borecams] will be very heavy. I would advise you to place an order as quickly as possible if you want one.” Vince adds: “If I were to replace my [Hawkeye optical borescope] today with another Hawkeye, it would cost me well over £700 [$1015 USD]. Stick on a video adapter and we are looking at four figures. That’s what makes the new Lyman digital borescope so attractive — at around [$260.00 USD] including a monitor — it’s an absolute steal!”

The system really works. Many of our Forum members have the system and they say it functions very well and is “very easy to set up and use”. Here’s what an Optics Planet Borecam buyer wrote: “I have used Hawkeye borescopes and know their quality. The Lyman worked as advertised and is a great tool for checking for leading, cleanliness of bore, and bore wear. The compact size, ability to take pictures, and store them are a big plus.”

Lyman BoreCam Review by Vince Bottomley

Lyman borecam Vince Bottomley Review Target Shooter Magazine

Lyman’s digital BoreCam is one of the hottest rifle/gunsmithing accessories on the market right now. The product sells out quickly whenever a vendor gets a few in stock. Make no mistake, this is a good product that works well, and, at around $300.00, is it affordable for most shooters. The BoreCam provides vital information about your bore and chamber, and has the ability to save images to an SD card.

Our British friend Vince Bottomley recently obtained a Lyman BoreCam and put it through its paces. Vince came away very impressed. He says it is an easy-to-use and very capable bore inspection tool at a fraction of the cost of a high-end optical borescope (such as the Hawkeye). Vince says serious shooters should definitely acquire one of these tools: “In my opinion, this product is one of the very best to come along in recent years and I predict that the demand for these [Lyman BoreCams] will be very heavy. I would advise you to place an order as quickly as possible if you want one.”

READ Full Review by Vince Bottomley for Target Shooter Magazine

Here are highlights from Vince’s review of the Lyman BoreCam: “If I were to replace my [Hawkeye optical borescope] today with another Hawkeye, it would cost me well over £700 – stick on a video adapter and we are looking at four figures. That’s what makes the new Lyman digital borescope so attractive – at around £250 including a monitor – it’s an absolute steal!

But £250 – with a video attachment and photo-capture facility – can this really be a useable borescope? Trust me it is! But what use is a borescope. Why do you need one? Well, whatever you shoot, the condition of your rifle’s bore is critical. And I’m not just talking about a bore that’s ‘shot-out’ – maybe you just aren’t cleaning it thoroughly. Or maybe some defect within the chamber or rifling is preventing your rifle delivering the kind of performance you expect. Even at £700, a borescope can be cost-effective – if it saves you the cost of just one new barrel.”

Lyman BoreCam Review Vince Bottomley

Vince explained how the BoreCam can quickly diagnose problems in a barrel: “A customer started to have difficulty chambering rounds in his 308 Target Rifle…. The borescope quickly revealed the problem – a hard ring of copper and carbon had built-up immediately in front of the chamber. When you use a bore-guide (and you always should do) it can sometimes ‘protect’ this first bit of the bore from the cleaning-brush. Although the rest of the bore was spotless, this tiny section was not. Once we knew where the problem was, it was simple matter to carefully clean it up.”

“A borescope will tell you if your cleaning regime is effective, or inspect for throat-erosion and the general condition of the rifling. In addition, it’s very useful to the gunsmith for inspecting newly-cut chambers – making sure they are free from scoring and other machining defects.” Vince also recommends using the BoreCam to inspect barrel crowns: “Tiny burrs can often be present on newly-cut crowns and even the minutest of damage to a crown… can play havoc with accuracy. For the serious shooter, you could say that a borescope is the equivalent of a doctor’s stethoscope.”

The Ugly Truth Revealed
Here are some inside-the-barrel photos Vince took with the Lyman BoreCam. Vince notes: “This barrel came out of the scrap-bin, but someone had actually been shooting this rifle before he finally gave up and came in for a new barrel. Shooting a barrel in this condition is really throwing good money down range! Buy a borescope and stop shooting long before your barrel gets into this state!”

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).

CLICK HERE to read Full Match Barrel Care Article.

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.

New Lyman BoreScope with Digital Screen and Output to Laptops

Every rifle shooter should have access to a borescope. These devices reveal the condition of the inside of your barrel. Do you have a carbon ring problem? Is there jacket fouling near the muzzle? Are the edges of your lands worn away? All these common conditions can be revealed by a quality borescope.

UPDATE: MSRP will be under $300.00 and the unit should be available in March. Lyman told us: “We expect to have these available in March 2015. The price is expected to be $299.95. We will have this available for pre-order via our website in early 2015.”

And now new digital/optical technology makes the borescope easier than ever to use. For 2015, Lyman will introduce a new, affordable borescope that employs digital imaging (with a micro-camera). You no longer have to peer into an old-fashioned eyepiece. With the new Lyman borescope you can view the inside of your barrel via a small portable display screen. That’s handy. In addition, the borescope images can be displayed on your laptop or mobile device. Lyman provides a USB cable and software that allows you to view the borescope’s image output on your computer (plus you can record images for future reference). The unit fits bores .20 caliber and larger.

borescope digital lens viewscreen USB ipad computer camera micro-camera

Sorry, we don’t have an exact price yet, but we’ve been told that this new product will be less expensive than current, conventional precision borescopes with glass-lens eyepieces. Here’s what Lyman says about it’s new product:

Lyman’s new Borescope provides active shooters with the means to carefully inspect the bores of their firearms for wear, throat erosion, tool marks, and other rifling or chamber damage, as well as for checking for fouling. The scope will fit 20 caliber and larger barrels and works with miniature camera technology. The display will show a clear image of the inside of the barrel and also allows you to take a photo of the bore. The image will storage on a standard SD card and can later be viewed on a computer or lap top. A separate cable (with USB connection) and CD are also available so that the Borescope rod can be connected directly to your computer or lap top. If you prefer to view only on your computer or lap-top, the Borescope rod is available separately (without the display unit) and plugs into the computer with a USB connection.

How to Wear Out a Barrel in One Afternoon…

Can sustained rapid-fire shooting with no cool-down period wear out a quality barrel more quickly? The answer is “Yes” according to Forum member LCazador, who recently did an interesting comparison test with two .243 Win barrels. He started off with two, identical, match-grade HV taper stainless barrels. Both were NEW at the start of testing, and LCazador shot the same load through each: 95gr match bullets with 38 grains of Hodgdon Varget. After giving both barrels the same, gentle 20-round break-in, 300 rounds were then fired through each barrel — in very different ways. Barrel condition and wear were monitored with a borescope.

Barrel One — Slow Fire, Cool Down Periods, Cleaning Every 50 Rounds
At the end of the 300-round test, Barrel One looked brand new. There was none of the severe fire cracking found in Barrel Two. This barrel was shot no more than 10 times without a cool down and firing was done at a much slower pace. Cleaning for this barrel was done every 50 shots.

Barrel Two — Fast Firing, No Waiting, Cleaning Every 100 Rounds
The second barrel, which received hard use and minimal cleaning, was severely damaged with severe fire cracking at the leade and throat. As a result, the barrel had to be re-chambered. This barrel was shot 100 rounds at time without cleaning and was shot up to 20 times in succession without a cool down.

Don’t let your barrel get too hot, and keep it clean. One afternoon can ruin a barrel!

Hawkeye Borescope imageMonitoring Barrel Wear with Borescope
Some folks worry too much about what their borescopes reveal — many barrels do not have to be “squeaky clean” to perform well. In fact some barrels run better after ten or more fouling shots. However, a borescope can be very helpful when your barrel starts losing accuracy for no apparent reason. Forum member FdShuster writes:

“A borescope is a positive way of backing up your suspicions when the rifle starts to throw an occasional (soon followed by more frequent) wild shot. Using the scope is also an excellent way to determine that the cause is barrel wear and not simply a need for a concentrated cleaning session to remove built up copper and more importantly, carbon fouling.

I’ve had a few barrels that gave every indication of being shot out. But I ‘scoped them out and found the cause to be nothing more than requiring a good cleaning. They then returned to their usual performance. There’s no guessing involved when you are able to get ‘up close and personal’ using the scope. The borescope also provides an excellent view of the all-important condition of the crown. My borescope is one of the most valuable investments I’ve ever made.”

Beyond the Bore-Scope — BEMIS Laser Bore Inspection Machine

Do you think your borescope is a state-of-the-art bore inspection device? Well think again. There is now something way more advanced than any optical borescope. A new laser-equipped scanning device can map the entire interior surface of a barrel bore. With this new technology you can now examine every land and every groove, millimeter by millimeter, from the chamber to the tip of the muzzle. The most minute flaw in a barrel can now be revealed.

Chesapeake Testing BEMIS laser bore scanner barrel inspection machineThe new device is called the BEMIS-SC™ (for Barrel Inspection Machine Small Caliber). Operated by Chesapeake Testing and Laser Techniques Company (LTC), BEMIS-SC performs non-destructive laser-based mapping of gun bores. The BEMIS-SC currently works with .22 caliber to .50 caliber (5.56 – 12.7 mm) barrels. The BEMIS captures thousands of highly accurate data points over the full length of a barrel. The inspection can be completed in mere minutes, with scan results displayed in graphical, tabular, and 3D visual formats. Here is a barrel cross-section, as scanned by the BEMIS-SC:

Chesapeake Testing BEMIS laser bore scanner barrel inspection machine

Until the 1980s, gun tube inspection had to be conducted by hand using a manual “star” gauge, a process that would take hours and provide minimal data. Electronic gauges were eventually developed along with the video bore scope, but these systems were still limited to very few, low-resolution data points. That has all changed with the BEMIS™, a huge leap forward in technology that is capable of rapidly capturing thousands of precise data points.

BEMIS-SC (Small Caliber) Barrel Inspection Machines
Chesapeake Testing BEMIS laser bore scanner barrel inspection machine

Chesapeake Testing commenced BEMIS-SC barrel inspection services in September 2014. Testing is performed in Chesapeake’s commercial barrel inspection laboratory, located in Belcamp, MD, minutes from the U.S. Army Aberdeen Proving Ground. While testing is currently limited to .22 to .50 caliber barrels, Chesapeake Testing will accommodate both smaller and larger calibers in the future.

“We have always focused on building our company around very unique technologies. BEMIS™ has changed the industry in regards to the inspection of weapon systems. We are excited to be an exclusive partner with LTC in this industry and look forward to contributing to the future of this technology,” says Jim Foulk, founder and president of Chesapeake Testing.
