A few months ago, I bought a Teslong with the screen. It is definitely hard to know what you're looking at in the beginning ;when everybody that shows you a barrel on UA-cam looks like a mirror. I saw cracks in carbon and thought it was fire cracking until I cleaned it. thank you for putting things in perspective. my buddies wanna borrow it and I tell them you will see things you don't wanna see.
The particular one I got sucks. For one, it will not mount into the USB-C port properly. It is way too loose. It also said that you could load the app onto your laptop, but it will not allow me to do it. I am returning that particular one.
Well now, I can really see that a borescope is a must have tool in the ole tool box ! I guess I know what the *next* purchase is !! Thanks for another awesome, informative video !!
Great video. For setting focus: I use an empty cartridge case for the barrel being inspected. The neck of the brass is going to get you the correct focal length of the mirror. 😎👍
Even the budget friendly generics can be a huge help in cleaning and solving problems but don’t be frightened by what you see as opposed to what you expect to see, even some bad looking barrels can shoot great! Ultimate reloader, I have the one you need to show what Drain cleaner does if you aren’t careful. Bought it second hand and it looks like lava rock!
I have seen many people destroy barrels trying to get that mirror finished barrel. While carbon can and will fowl your barrel, copper actually is beneficial in many cases. Obviously carbon is harder than your barrel and therefore will only cause a source of buildup for pressure issues, but copper is softer. It will fill in the defects in the barrel and increase accuracy. And because its softer any coper buildup that is too high will essentially be wiped away as the next bullet passes by. its like spreading spackle against a crack on a wall. The first few times you wipe a large lump of spackle against a wall the crack will fill in. But after so many times there will be no more spackle getting applied no matter how much you apply and smear using your spreader. It just continues to wipe off. The wall is harder than the spackle so it simply wipes off. I have seen many people use horrifically caustic materials to dissolve the coper and they wind up dissolving bits of their barrel while they are at it. The solvent will find its way into those imperfections the coper previously filled and will often make those imperfections larger and larger as they find more surface area to dissolve leading to the need to clean your barrel more often and wear it out quicker. The effect is what you describe. lava rocks. If they are not careful with it they could ruin the barrel very quickly. But people are in a panic because they are not seeing a shiny polished barrel and we are conditioned to think that a clean barrel should look like its brand new and never fired. All that is needed is for the carbon to get removed. The coper can stay. it in general is doing more good than harm. With coper, if a wire bush cannot dislodge it, it isn't doing you any harm.
Second best tool I bought next to a chronograph. After you look at a few barrels you quickly learn a good barrel from a not so good barrel. What is amazing is how rough one barrel can be and still shoot a "few" phenomenal groups when it fouled the right amount.. lol
Been using scopes since medical endoscopes were the only 'quality' option (early 80's), and a selection of scope tube diameter o-rings are invaluable for centering the scope in the bore of you aren't going to change the mirror. Or your bores are larger than biggest mirror. LEDs are a HUGE improvement over C-cell powered incandescent scopes. I'll be ordering a Lyman tonight. Few of my rifles have throats as pristine as the rifles you showed, and my original 300 Jarrett barrel was plenty accurate until the "alligator back" erosion had migrated over 4" down the bore. Thanks for the video. You definitely sold a Lyman 2.0 to this 62yr old hunter.
Several years ago, I bought a used rifle. The bore seemed to be okay, but it never shot very well, no matter how much I fiddled with bedding or load combinations. It wasn't until I acquired a Teslong borescope that I saw the problem- the throat was completely trashed, with severe fire cracking. Had I had the borescope when first looking, I never would have bought that rifle.
Thank you! Have 2 bore scopes, but didn't realize how handy they were til now! Bought a flintlock a couple years ago. Brought my laptop and scope to the dealer to inspect the rifle. Turned out to be in very good shape and fully functional. Just turned to the right and smiled @ it. Spent a good 2 days polishing brass and finishing wood (reproduction .41 cal). Beautiful piece of newer history. Watch all of your vids JIC!
Good video! I've had a Lyman borescope for several years now and it is definitely scary to look through... But, for a low resolution, wired unit, it all performs well. Some of my older barrels look absolutely horrible but still perform their job well. I looked in an older pistol when I first got the borescope and had a scare. Giant, long crack along with some smaller ones! I ran a patch through it to get a better look and the cracks were gone. Pocket lint! 😂 Beware the hair!
great video. Maybe next one show what throat erosion looks like. Always a good point to say a barrel may look like crap- but shoot bug holes. My Hawkeye is Hard To Use- you have to contort yourself to keep it and your eye aligned.
Gunsmith here: I once had a customer with a bolt that was locked up. He had placed the rifle in an after market stock and the front action screw was interfering with the bolt on that particular model. After re torturing the action screws I used a borescope to count the number of threads I needed to shorten the screw. I know there's other ways to do that job that's just what i happened to use since i already had the bore scope out.
It’d be awesome to see you put that 22-250 barrel back on an action to see what kind of accuracy it is producing. Then clean the bore, re-crown, and see what the improvements are.
When you were looking in the barrel and talking about bolt actions you went in to the chamber to show the carbon ring. It looked like a dent where the chamber transitions to the rifling at the carbon ring. Is that a dent of some sort?
Would you recommend this Lyman scope over the regularly used Teslong ones? Being able to use an iPad screen is nice and the color contrast and sharpness also looked to be better than teslong. Would you say that’s an accurate statement?
I haven’t used a new Lyman, but teslong wise I have the Wi-Fi one I use with an I phone or my gaming PC. Results are more than adequate for what I’ve done. There’s a couple videos on my channel of a 460 Smith clean and leaded, and some footage of a savage 338lm if you wanted to see its image quality.
@@Ultimatereloader cool. I did not know what I was looking at. I want a bore scope just not sure how often I would use it. I’m so curious about what the actual issue is with that Mossberg. Good UA-cam channel, bore scope channel. We have people testing ammo. Would be nice to see people bore scoping.
@@Ultimatereloaderwhat are your thoughts on how the mossberg barrel looked? In my opinion the freebore/ lands and grooves looked straight and acceptable. Love to hear your thoughts?
A how to clean video would be helpful too. With the bore scope you can often see quite a bit of carbon and copper and just your regular cleaning usually is not enough to remove it.
Been deer hunting in central KY with a Mark V in 340 Weatherby for close to 35 years or more now. I'd be scared to death to even think about what the fire cracking would look like in my rifle. I'd probably stop using it !
My mid '60's .257 Weatherby that was purchased used w/o the benefit of looking down the barrel with a bore scope wasn't grouping at all. I wondered what condition the barrel was in & bought a Teslong & ran it down the barrel. That 1st look was SCARY! It had a lot of copper & carbon build up & serious 'alligator skin' look to the throat, as well as quite a few squiggly lint like pits in the barrel (nothing like his 6.5 Carcano!). After a very thorough cleaning with both Carbon & Copper solvent & a little scrubbing with JB bore paste, he alligator skin is still in the throat & squiggle pits scattered through out the barrel, but at least it's shiny & shoots acceptable groups now.
Interesting video , on the 6gt around 13.22 is there a big dint or groove in the throat area? Did that not cause any problems? Has it been caused when reaming ?
I can't Unsee my rough as a cob Savage 112FV varminter.. 😳 but the dang thing shoots little tiny bug holes. It defies physics. I use a Teslong wired version. It's fine for bench work.
Gavin I love my Arisaka’s. I bought a used sporterized hunting rifle Type99 in 7.7 Japanese. I couldn’t get it to shoot worth a damn. Got a bore scope and, oh no!!!!! There’s a huge gouge and burr halfway down the bore. How it got there is anyone’s guess. As I got towards the muzzle I saw what looked like a bunch of spiders webs. I wish there was a way to send you the video! I was freaked out!! I finished cleaning the rifle, double checked it, it was still there. I put the rifle away and haven’t touched it since. The cracks look like spider’s webs, or a cracked eggs. And how does a gouge and burr that big get halfway down a bore? Any help is appreciated!
@@eggbert191 yeah, advertising. I took a chance on teslong when they first came out. They had a promo where is you wrote a review, it was free, and it was only $50 if you didn't. I was pretty shocked and surprised that it wasn't hot garbage. That was 5 years ago. I have no doubt that there are better ones, but for 95% of people, the $60 teslong will do everything they ever need from a bore scope.
Lyman must have made some improvements in their borescope. I bought mine shortly after it was introduced and the image quality is no where near what you are showing in this video. I ended up buying a Teslong and have been quite happy with it.
Recently bought a Browning B78. 22-250 chamber. Barrel is in really bad condition lots of rust and some pitting. You mean using JB paste do you also use Kroil oil? My plan is to start with that combination and have been soaking the barrel for about a week with Kroil oil. I’m going to use a 20 caliber Iosso brush with patch wrapped around it and gradually work up to the.224 brush. What do you think about my plan. Any suggestions would be appreciated greatly. Thanks
I once cleaned an old .284 Winchester, soak the barrel with hoppes for a day, then scrub and patch for half an hour, repeat every day until no more copper on patches. I think it took about two weeks. You didn't need a bore scope to see the pitting! I reckon I could have smelted the copper on the patch into an ingot! Never did find out if it shot any good after that. My two cents is: start with a new barrel and clean after every use, even if it was one shot or an un fired hunting trip. Oil the barrel for storage, and make sure you clean the barrel before shooting. That's all about steel barrels, stainless probably less maintenance. Hope Gavin replies to you.
All the footage shows the barrel removed. I have guns with 24-26 inch barrels and want to see the bore without removing it from the action. The Teslong does that for less money. Can't see this working with a 26-28 inch barrel going in through the back of the action...
15:00 I hope you didn't pay more than $50 for that smooth bore carcano.... That's one of the worst surplus bores I have ever seen on any rifle that was not already retired as a wall hanger
Hey Gavin I have a question for you. I bought a shilen 223 barrel for my AR and I noticed at the gas port there is a good a pretty good size chunk missing I've had other barrels do this before and I'm wondering if it's a problem I should be worried about. Will it affect very fine accuracy

Before you purchased that bore scope, did you have a problem? Was your rifle shooting badly? Does it shoot better now?
