Teslong Bore Scope
 
Welp, my Teslong bore scope, arrive today, hook up was fast and easy. I ran it up and down the barrels of my Winchester Wildcat, my RPRF and my 1951 Remington 510 TargetMaster.

I not really sure of what I looking at, I see the lands and the grooves, and what look like light scratches. Are they from the rifling or from the bullets, or a combination of both.

The Remington, which was bought at a estate sale, was in battered condition, but after a clean up, shoots well. There are obvious splotches and pock marks in the bore, but the lands and grooves, are quite visible. Not only was the stock and metal on the bolt handle and barrel scuffed and the bluing worn away, but the inside of the barrel was exceedingly dirty, it was a chore to clean.

The bore scope is an interesting tool, to have, whether I ever get to fully understand what I looking at, is to be seen.

The fine scratches you see are the result of the silica particles in the primer residue
being dragged through the bore by each consecutive bullet fired.

Maybe....maybe not

PW, unlikely those barrels were freshly hand lappped. :D

Those scratches are due to the silica particles.
Calfee and Kolbe both acknowledge that the silica particles produce that wear pattern.

bore scope
 
Boilerjack, you did well to buy a bore scope. You will learn how to read what it shows with time. I use my scope on a regular basis. Some folks think you are better off leaving them in the box but I look at a bore scope as a tool. Looking down a barrel with a light on one end just shows it is not plugged up with bugs. The Teslong is a good starter to learn about carbon ring, copper streaks, carbon build up, worn throated area, crowns, tooling marks, etc.

Boilerjack22 07-07-2021 06:03 PM

The true intent of my first post, was easy it is to get a in time look-see at the bore condition in your firearms. The scope to my front door, was $50, from the time I opened the package, to seeing lands and grooves up close and personal was about 5 minutes.

At this time, can I accurately tell you about fine abrasion marks are telling me, no, can I see pock marks in the barrel, can I see long term neglect in the bore of my Remington, yes I can. Was I surprised I saw clearly defined lands and grooves that are about 70 yrs old, and that I was also surprise about how well the majority of the barrel bore looks, yes I am.

When I ran it up and down the barrel of the RPRF, the Winchester Wildcat, the RARF and the Henry pump, I could clearly see the lands and grooves, again fine scratches, but no build up of any kind, no pock marks or anything that looked abnormal, from what I imagined it should look like. So far my cleaning reunite is working.

Again an interesting tool, relatively cheap, easy to set and use, Im only sorry I did not get one sooner.

A lot of what you see in a factory barrel is machining marks left by the tooling. The poc-marks are probably the result of rust but could just as well be from metal defects made worse by the hot gases passing through under high pressure just behind the bullet as it travels along.

The good news is most of the time none of those things affect accuracy much if at all unless they are severe. I have several OLD rifles that have bores that look like a dirt road after a heavy rain and they still shoot sub MOA.

A clean barrel will be a light gray to silver color, black is carbon, and in the throat (the dreaded carbon ring) carbon looks like wet coffee grounds packed down and stuck to the walls. Lead looks like a lighter gray patch or streak that runs parallel to the bore usually on the lands. It looks almost like cold butter on white bread and does not have the same texture as the barrel's steel but rather it will be smoother. Copper looks yellow to orange much the same shape as the lead but tends to be on both the lands and grooves.

You will also see little blobs of yellow from time to time in the barrel. My guess is that this is unburned sulfur that has precipitated out of the hot gas. I just ignore it for the most part.

PigButtons 07-07-2021 06:52 PM

I had a thread on another site asking what other uses people found for their bore scope and some of the answers were very interesting. Here's a few.

Looking in a drain to see the clog.
looking inside a spark plug hole to see a burnt valve
looking inside reloading dies to see rust, scratches and contamination
looking in one's nose, ear, mouth, to find "problems"
looking behind heavy furniture for lost items

Boilerjack22 07-07-2021 07:41 PM

Because of work, I have multiple bore scopes, just none this small in diameter. The next smallest one, I have, is 1/2 in diameter.


I wonder what the barrel that just had 200-300 rounds run through it, would look like before and after cleaning??

jaia 07-07-2021 08:00 PM

I can answer that. ;)

Now that you have a borescope, so can you. :D

Boilerjack22 07-07-2021 09:00 PM

Yep!

Coincidently I just got my first Teslong bore scope delivered yesterday too. Paid the same $50, and it was just plug and play to my laptop with windows 10. I was peering at the scary lookin' innards of a rifle barrel in about 5 minutes too.

Had a hard time putting it down so I could call it a day and get some sleep because it was so fascinating to see things I've never been able to see before on my guns. A great tool to satisfy my OCD tendencies, and at only $50 a no-brainer to anybody even mildly interested in their firearms.

carbineone 07-08-2021 02:52 PM

They must have went up in price some..I think mine was less than 40.00 shipped..

I really like it..I did think something was wrong with mine when I bought it..It was just out of focus and fuzzy..I realized I just had it out of focus with the little threaded lock ring for the lens..I have seen reviews on Amazon that others have sent them back for this reason..It was not the scopes fault..It was my user error:)

LuckyGuy 07-08-2021 04:26 PM

I agree.

The vendors probably hate it when people send stuff back because they say defective. It was all the person fault that bought it, did not read the instructions. We all know about stupid people.:gun4:

Thanks to all the positive comments here, I just ordered a Teslong scope.

As a collector or better, an accumulator of vintage .22's it will be very handy to access bore condition.

And the last one I brought home was super nice outside, but the bore turned out to be a sewer pipe. I need to see what is going on in there.

I hate making bad reviews. My Teslong arrived yesterday and I was looking forward to trying it out. Now for the record, I have been fooling around with computers since the operating system was DOS so I'm not a computer dummy. Actually since 1979.

I first hooked it up to my wife Window 10 laptop. The light came on but I could not access the camera. I can only access the camera that is already in the laptop.

So I hooked up to my Win 10 Desktop and the light flashed as I plugged it in but even when I go to the device and printer page, it shows up, not as a camera but an unknown device. Ran the trouble shooter, restarted the computer and still no joy.

Life is too short for me to have to spend an hour or so trying to get the blasted thing to work so it is going back.

I find if I unscrew the mirror a little bit from the camera, I can get a much better focused image . I use metal tape to tape it in place and cover exposed threads .

Do you get a funky looking camera icon on the upper right side after going to the camera app? My Windows 10 displays this "button" when the teslong is plugged in. I click on it and viola. At first I thought this was just the reverse camera button.

MKnarr 07-17-2021 03:55 PM

carbine. after your comment, I unpacked the thing, fired up the Laptop and got the camera app started and THEN noticed a camera button in the upper right corner of the app that had a camera button that obviously was meant to "change" cameras and of course the "other camera" was the Teslong. Until now I was so upset that only the laptop camera came up that I never noticed the button to change cameras.

But now I am missing the coupling that is meant to hold the mirror in place once you have the focus adjusted. But I think I can make if I have the correct tap threads. It looks like 10-32 but maybe not.

It also occurred to me since it is a desktop it doesn't have a camera so it doesn't have a camera app so it doesn't recognize a camera when plugged in. I have now installed the camera app so if I decide to use the bore scope on the desktop is should also work there.

Thanks guys and especially carbine and once adjusted the image is nice and showed that I am able to remove the carbon ring in my Anschutz Shilen barrel

MKnarr 07-19-2021 03:57 PM

Today I got to put the Teslong Bore scope to a use. My Anschutz which was used in "My Crazy Ammo Test #2 on Saturday had about 145 rounds through
it since it was cleaned for that test.
Here is picture of the carbon ring forming,
https://i.imgur.com/OC135hb.jpg

The carbon ring on my Shilen barrel with Octagon rifling and an ECX reamer started the carbon build up at the place where the case ends and extends up the leade about 1/8 inch or half way at this time For 145 shots this isn't a lot and in my rifle doesn't seem to be a problem until about 400 rounds.
Here is a picture again after cleaning the throat.
https://i.imgur.com/4pDnWiL.jpg

I use a 17 caliber nylon brush with a bit of 0000 bronze wool wrapped around it and a short rod. I then scrubbed the chamber with 20 short rapid strokes. This time I used Kroil only. I would guess after more rounds and more build up I may have to use TM Solution which is what I usually use.

In that test I alternated match ammo with bulk ammo and some had copper plating. There was no lead build up or shiny copper anywhere before cleaning. I suspect that hand lapped barrels do tend to foul less with lead. I have a S&W M&P .22LR pistol made by Walther and that barrel leads terrible.

Pressman 07-19-2021 09:08 PM

I received mine last Tuesday, why I waited so long is beyond me. With more than a dozen .22 rimfires, So far: My neat little Iver Johnson has no rifling, it looks like someone started cutting then stopped after an inch, the rest is a roughly drilled hole; the DSM-34 Mauser that Bubba got ahold of was allowed to get dirt and rust in the bore 6 inches from the muzzle, it may shoot but needs a better front sight; and sadly my BR-50 build has a brand new, rusted out junk Shilen barrel. It seems the elderly gentleman who built it just used what ever was on hand and the barrel is badly pitted for 12 inches from the muzzle back.
On the + side several others that have been shooting well have very nice bores.

I have not seen any built up lead in any barrel, yet.

My Teslong borescope is the one with the fixed rod and the monitor. After using it for a while, I was somewhat disappointed at first. After charging it up for the second or third time, I downloaded some pics to the computer. It's like a camera - the photos are in the folders. After enlarging the photos on the computer screen, I realized there is a slight learning curve between using just the Teslong monitor and the enlarged pic on the computer screen. I've got it. Now I realize what I am seeing using the Teslong monitor. I just hate it took me a while to figure it out. It probably helps that I have a Lyman borescope as well, and used it for a few years. Yes, I like the Teslong borescope:

Only slight problem is the 90 degree mirror still moves around just a bit using simple picture paste. I have been considering this Loctite product:

MKnarr 07-20-2021 08:41 AM

amohog. There is a little collar that screws out and holds the mirror in place. I thought it was missing and apparently others think so as well. Turns out it is the last 1/8 inch of the SS shaft. It's hard to see but you will see a slight line in the shaft. When I e mailed [email protected] I thought mine was missing and then found it. They said "no problem, that's a common issue".

Yes, I have been aware of this from the get go. I have also worked as a mechanic and was certified as such. It is a "lock nut" so to speak - to keep the 90 degree attachment in proper focus. This is where I need to apply a dab of adhesive between then when "finger tightening" to keep it in focus during use. If they are both aluminum, it's probably a no go for the loctite.

Hawkeye57 07-20-2021 12:30 PM

My rigged arrived a week ago. When it got here I only put it in a barrel to see if it worked then put it away.

Today I cleaned a few guns and tried it out. I already had a camera app in the laptop with windows 10 for the camera that has tape over it. Went to the app, clicked the change camera icon, and up and running.
It tells you about the lock ring and focusing in the manual, if we stop to look. :D I had trouble with it loosening in the first attempt. I then snugged the ring up, then held onto the ring and tip while tightening them together, and haven't had it come loose. I've tried to avoid rotating counterclockwise when in the bore where it's tighter.
