Agreed, some of the other barrels on my channel are on standard quality guns and they looked better. This shot really well though. I didn't regret my purchase and later sold it with a clear conscience. The next owner reached out to me not too long ago and told me he had good accuracy also.

He still shoots it some for the fun of it. When he quit hunting it stopped getting as much attention.

@@Nathan_King I have several of those type guns...they don't get shot much...My first old Ruger M77 that I ever bought is the same...I'd never sell it for sentimental reasons.

While manufacturing tolerances have tightened up considerably in the last 50 years, a 1.5 MOA rifle is still a serious game getter. As a shooter, I get excited with the ragged hole accuracy too- but hunting accuracy does not demand this for meat on the pole.

Pretty well. I only shot factory ammo and the Terminal Ascent shot about 2/3rds MOA as I remember. I bought that barrel for a hunting trip and decided afterwards I didn't need it so sold it. The newer owner texted me back and said he was getting the same. I'd be willing to guess it'd be a .5MOA shooter with handloads, if not better. My other two Shilen barrels can shoot .25-.3MOA with boxes of ammo that have the velocity the barrel likes. This one might have done the same, I'm just not sure. Thank you for watching and commenting.

nope, these barrels are hand lapped and way better than this, it is not a howa barrel how it got through QC is a mystery it needs to go back

I try to keep the mirror clean and then just work around it. Seems like making sure the image is focused helps a little. Being able to turn the lights down just a little would be nice at times, but based on the design I don't think there is anything you can do that makes a notable difference. Thanks for watching! I'll be back to uploading videos in a few months.

Teslong offers mirrors with a ring painted around. The mirror is at a slightly different angle and doesn't give so much glare. Unfortunately, they provide only one of these with the borescope. If you order a replacement mirror set, you get one "no glare" and two or three "glare" models. Grrrrrrrrrr

Teslong NTG100. Thanks for watching.

Thanks! I won't be able to make any for a couple months due to business requirements. I'll start back as soon as I can.

@@Nathan_King wish you all the best

I appreciate you watching and I'm glad you enjoy them. Unfortunately Uncle Sam decided to send me overseas, so it'll be a while before I can upload another one.

You'll probably like the video I recorded after this one then!

CHF are gloss inside, but not as accurate after repetitive shots such as competition. CHF do last very well in regard to lifespan

The gun community has speculated on gun cleaning procedures for decades. Can't argue with the borescope. Best $55 I've ever spent on a gun accessory. I sure hope others have found it helpful and informative and thanks for the comment. I won't be able to upload any vidoes for a few more months, but I will start back up when I can!

True, but man there are a lot of really good ones! It's a great time to be into precision shooting.

The original video ("before") is here - czcams.com/video/tWsB55F5SRA/video.html sorry, no video editing skills to put them together haha. All carbon came out with Iosso after a second cleaning. I used one of their brushes and was sure to keep the cream on the tip of the bristles, not down in-between them. It didn't do anything when it got down in the bristles, so I tried the tips and that worked.

I meant pitting not putting!!!

I've shot this one out to 600 yards and my 260 Rem out to 1k. Regardless of how many internet forum posts I read claiming it, I don't believe any barrel shoots consistently small groups with factory ammo. OAL length varies too much and velocity swings are too great from box to box, much less winter to summer temps. But with the right ammo and shooting at the right muzzle velocity, these two barrels make really tight groups. Hard to get picky about the looks when they shoot as well as they do. But that's why I wanted to post these - to help other shooters make informed decisions. There are plenty of fantastic barrel manufacturers and others probably do look better. I'm glad I could at least provide my experiences to help you with your decisions.

Precision shooting has grown exponentially lately, so I'm not sure loosing market share has to equate to their sales going down. I really have no idea though. Considering my ability and that I was using factory ammo, I was perfectly happy with its accuracy for the 22-ish shots I took with it. I'd probably argue the way the inside of the barrel looks shouldn't matter that much if the barrel is accurate.

@@Nathan_King I'm basing my thoughts on the other premium barrel makers that have taken hold. I like their barrels and they usually look a lot better than that as they do hand lap them. That one looked like maybe they skipped that step. As far as accuracy goes, most good factory offerings and modern barrels shoot well nowadays.

I'll have to try that at some point. I'm more than happy with Iosso, but the borescope will let us know! I'm fresh out of dirty barrels now though. Haha

Using Wipe Out now on a 243. Soaked it a couple overnighters and cleaned about 6 times during a full day. It's working but not amazing. Borescope still shows plenty of crud. I have about 60 rounds down the barrel. It does seem to be chipping away at the carbon ring.

Teslong NTG100

After about 20 fouling shots, its back to around 1.5MOA which is normal with the ammo we shoot through it.

I asked if I could send the video to them and talk to someone because i doubted it was handlapped. Their response was "Was there a problem with the way the barrel is shooting? If there is a problem, we would like to have the barrel sent back to us so that our QA department can look at the barrel and verify it is within spec. If we find that the barrel is in spec, you would be responsible for shipping back to you. If it is out of spec or they determine something needs to be done to correct the barrel we would take care of it and ship it back to you at no charge. " I told them I wasn't interested in sending it in unless I could talk to someone first because I didn't want to potentially waste money on shipping and because my first 22 shots didn't raise any accuracy concerns. I didn't receive another response.

@@Nathan_King I would bet they scope them the same way you did and cull the ones that look real good and save them for their sponsored shooters and we get the rest.

@@Nathan_King I have a shilen barrel too however it is .22 rim and through the scope it looks much worse in the grooves and lands (tons of tooling scratches) , "what they said "(shilen) go shoot it first then call if it don't work .The big problem is rimfire doesn't make enough heat and pressure to fire lap. .The only way i could make it work is with lots of slugging with abrasive grease(if i did wrong no warranty) . so it sits on the corner

@howardjohnson5734 hate to hear that. If it's just in the corner collecting dust, maybe its worth trying to fix it? Sounds like the warranty is effectively useless to you already.

It's a $50, $55 model from Teslong. I think specifically NTG100.

@@Nathan_King wow!? I’ve used one from teslong in the past and returned it because it wasn’t as clear as yours 🤔 thanks for the reply

@@mrcbrrr7484 I'd add that focusing can be a little finicky because you have to twist the mirror. Not sure if your model focused the same way, but it's a thought for you.

I can't remember if Shilen does button or hammer. But definitely part of the manufacturing process, whichever they use.

@@Nathan_King Shilen utilizes button rifling. Nearly every aftermarket barrel maker uses button rifling or cut rifling. Hammer forging equipment is very expensive and generally only the big manufacturers can afford to use that process.

They were a great deal a few years back. Now they are just as expensive as far as I've seen. Where'd you buy it?

@@Nathan_King Northland Shooting. Strangely, if you buy direct from Criterion, they are more expensive than from Northland.

@@patdennis3751 that's where I bought all three of my Shilens. I picked Shilen originally because you could buy them blued and I've been happy so I've stayed with them. I may try something else just because next time.

@@Nathan_King well maybe Shilen is sending their second string barrels to retailers? I think quality control is lacking with some brands. Recently, I bought a Proof Research barrel that cost a small fortune. As soon as I opened the box I put my borescope through it. NOT impressed. This was a $600+ , stainless, so called hand lapped match barrel and it had lots of pitting! I sent pictures to Proof and at first they tried telling me I was looking at oil in the bore. After a bit of arguing, they basically admitted to it and still would not replace it. I was told to shoot it and if it didn't shoot they may replace it. I will never buy another Proof Research barrel regardless of who is selling it. I still have it in it's unfired condition if they want to do the right thing and send me what I paid for. For me, my next barrel will either be Brux or Kreiger. I like my Criterion and it shoots very well so another is always an option.

The owner said after he did an initial cleaning it looked like it had been polished. As far as I know it still hasn't been shot, but holding it you could tell it's a high quality weapon. I wouldn't have a problem purchasing one!

I'm not sure. I shot it for a while before i understood the value of keeping track. Maybe 1k at the time of th video?

Im not sure hand lapping could even remove those marks, they are pretty pronounced ridges from the button. they happen in every button rifled barrel ive scoped but dont seem to effect accuracy(consistency) any.

Teslong. It was about $50 on amazon.

@@Nathan_King wow.. I could never get an image nearly that clear with my teslong. You’re using the regular monitor that came with it?

@@CallMeUbba it connects directly to a cell phone and is recorded by the phone. No screen came with it. It usually takes me a couple of tries to get the mirror the correct distance away so it's focused. But yes, I agree, it's quite clear for what it is.

@@Nathan_King Well, you’re right. I just tried mine connected to my laptop and it’s way better. Can actually see the copper and carbon now. I was literally 30 min away from buying a Hawkeye set on eBay too. Hope someone outbids me now 😂

@@CallMeUbba well, did you "win" the auction? Haha

Between this rifle and my dad's 30-06 (check out that video too), I'm a believer! My dad was completely shocked when I showed him the video of his barrel still being dirty.
