Is a Bore Scope worth buying? - And if so, what one?

[hps1]

Works fine with my Samsung S8 phone. Download from Google play store is "Teslong HD". Just plug in the camera using the provided adapter, allow the app access to camera and storage and you're all set.

Here's a nice picture of the bore of my Marlin 1894... Very nice tool marks! Still shoots great at 25m though!

Thanks. So the camera is actually connected to the camera (or computer) via a hard wire? I thought some models used wifi or blue tooth or green ear or some other hi tech terminology unknown to this old codger?? It would be beneficial in my instance to be able to cross-connect to both phone & computer but what do I know. I'll answer that...not much.

Back to your pictures. Amazing. Just proves that the scope will not tell us whether a barrel will shoot or not, just whether we're getting it clean or not!

Your pictures bring up another question for any machinists among us. What the heck causes those (amazingly uniform) machine marks in the grooves. I never had given it a lot of thought and just figured that they were just a chip caught in the drill bit, but if that were the case they would be on the lands, not the grooves.

Can't believe they are chatter marks from the button; could it be the steel used in the barrel caused by chips breaking off as they curl up in front of the cutter?? Whatever caused them they are amazingly evenly spaced and obviously have little effect on accuracy (in this case, at least).

Thanks for your answer and pictures, WS.

I guess there are different versions, the one I have is the cheaper version with physical connection. Wish I had know about the wifi/Bluetooth version as I found the adapter to be a bit finicky with my phone (if you moved the adapter slightly it would disconnect). There is a generous amount of cable though so even when I'm inspecting a 28" length bore there is enough cable coiled up to prevent the adapter from wiggling too much.

Anyway, back to the pictures. I've attached another couple of pictures of my Marlin. The machining marks start around 2-4" from the chamber and continue for another 10" or so then stop. The pictures are the transition between the mid bore and the muzzle.

I have no idea what would cause such marks in a barrel.

Edit: Another good use of the bore scope is for inspecting military surplus rifles as it gives you an opportunity to see if there's any major pitting, frosting etc which may help distinguish a shooter from a wall hanger.

I think the Teslong scope is an amazing bargain. For $50 you have the same sort of picture quality that was only available at the cost of maybe $4-500 just a couple of years ago. It's small enough to fit inside .22lr rimfires and my .223 and very clear on my PC, laptop, android tablet and android phone.

The cheap endoscopes don't begin to compare for quality and seldom have the all important right angle mirror.
You may fined other uses for it too.

I'll have to do some more reading but I believe I saw where some had the wifi capability, but may just be dreaming.

That is even more puzzling since the marks stop so abruptly. Hopefully some machinists on board will shed some light on it. Guess it's not the lot of steel used so must be something else.

I believe these are "chatter" marks caused buy the "button" vibrating as it's pushed through the bore during the rifling process. I've come across this before on a target rifle I bought new several years ago. I was so hacked off I actually made myself a borescope to see what the problem was - end result was that I posted the video on youtube and the company sent me a new barrel.
