Borescope

[7mmweatherby]

Hello Weatherby Nation

 I been pondering on purchasing borescope but not spending a fortune on one . Like see what’s going on in the barrel when cleaning and after long string of shots and anything that’s finicky that loading for that may cause a problem. Any suggestions or recommendations are welcome

Thanks

I've heard from several people who purchased borescopes that their barrels had much more copper than they thought (pre-scoping). I defiantly believe a borescope is invaluable for assessing a used rifle for leade erosion and the smoothness of the bore. The same goes for comparing new barrels, if you ever need to.

Zonie had a post a couple years back. On the Teslong Digital Borescope. I bought one myself fits 20 cal and larger and there a app to go right to your phone so you can take screen shots.
I forget the actual price but $68 bucks seems to ring a bell. A Great deal for what it does.

The Gradient lens Hawkeye is remarkable. Very expensive though. I’ve never used one of the cheaper brands.

I don't have one but have heard the Lyman Borecam is worth a look.

 I got a teslong borescope about a week ago. I am still playing with it. Looked through only a few rifle barrels so far. Ordered it through Midway with total cost was about 100 bucks. It is connected to my cell phone and the image is outstanding. As mentioned with an eye looking down a bore it's shiny clean. The scope shows copper fouling on all 3 rifles near the chamber and little to none near the muzzle. All show machine marks in the barrels, all the rifles shoot nice groups. I am finding a few cleaning patch threads in all bores.   
Today I spent some time looking into the newest rifle barrel I have. Christain Arms .308 win. with about 80 rounds fired through it. Only barrel so far that I found a mark in the chamber like a really small chip taken out where the neck lays in the chamber. I took a photo and am going to send it to the company asking if it's a problem.
Next will be looking after shooting before cleaning.
The model is ntg150w

I purchased a Teslong about 2 years ago. Great product to check for carbon rings and how you clean your barrel, but my advice is don't get to anal over what you see. Two of the worst looking barrels I have are on my 22/250 and 300 Win mag. Both rifles shoot 1/2 MOA 5 shot groups. In fact the inside of my 300 Wim mag could scare you. I've seen the inside of sewer pipes that looked better. My 22/250 is a Sako and after I purchased it I scoped it and asked for a refund. The throat was good but the barrel from about 1/2 way down to the muzzle looked real bad. The seller asked me to try it before the refund. It shot 1/2 MOA and I still have it. JME

 I agree with the above statements. Even thou we clean a barrel/action well and looks great with the naked eye. The borescope can or will show fouling. If the rifle is shooting up to your own standards with some fouling and tools marks. No need to change up your cleaning methods or attempt fixing what ain't broken.
BTW, I have an older win 94 30-30 cal. that when purchased was cheap due to bore pitting. I don't shoot it much, but it shoots fine. My handloads shoot about 2.5 to 3 inch 5 shot groups at 100 yds. I doubt when new it shot much better.

Ordered the teslong bore scope this morning (Wi-Fi option) thanks for all your replies.

 When I down loaded the app. and tried to use it. I have adds popping up and at did not realize I was clicking on adds not opening the app. Otherwise it took me a few mins to learn how to get it working.
BTW, I scoped a nearly new Christinson Arms .308. I found a chip or gouge in the chamber. It is where the shoulder and neck met. Rifle shoots well, brass is not harmed. It's likely cosmetic. I contacted the co and they want it back to check it out. I am sending it back and let them decide.

Thanks for heads up on apps  ….Iam sure going be interesting when I get started borescoping

One thing the Teslong bore scope  taught me was finding  easier ways to clean a barrel chemically by trial & error without a lot of back and forth wearing out bore brushes and a lot of work.  first time I looked at my dad's old pre-64 winchester it looked like it was gold plated copper fouled down the entire length of the barrel and the rifle shot pretty darn well which kind of surprised me.  I finally decided on using sharp shoot r precision  ( the liquid wipe out  patch-out) along with (wipe out accelerator) and sometimes every now and then I use (wipe out tactical advantage carbon/powder remover).  Follow directions when using wipe out procucts and even if it"s totally copper fouled it may take multiple cleaning try's and using a bore scope to verify where the heavy fouling spots are located in the barrel  it should come clean UNLESS the barrel is so pitted and rough nothing is going to get it out at that point just shoot it and not worry about it.  I do think sometimes and this depends upon the weapons barrel a little fouling is not a bad thing to settle the barrel down.  I do still use KG-12 and Boretech mostly for verifying copper is out with a clean patch.  I  think you might be surprised just how imperfect even new barrels are.

Received borescope (teslong) unpackaged to my surprise was how sharp and clear images is .I borescoped my r700 30-06 that going be sending to Jim Hart for barrel replacement that accuracy fell off last spring and summer got much worse to point after few rounds falls completely off anyways after scoping told the tail rifling chipped all up right out from chamber …..borescoped my terramark 6.5 -300 very sharp and smooth ……..very pleased with teslong borescope

I attached picture of rifling on r700 30-06

 What I am seeing in some of my guns (Rifles and handguns) leads to more questions. I have not even scoped half of my stuff. I found what I believe is a carbon ring in the mark V 7mm wby. in the neck or shoulder area of the chamber. It is built up in a type of chucky material. So far it has not caused any chambering or brass problems. The barrel is a aftermarket barrel in a medium heavy 26 inch. I purchased it used with a varmint reticle Leupold and unknown how much it's been fired. It shoots tiny groups with 140, 150 and 160 bullets. Rifling is in great shape with 1 in 9 twist.     

Most of the rifles I am looking at have a dark ring in the chamber where the mouth of the case sits just before the rifling. With the freebore of this rifle, I first guessed that is what I am seeing, but there is a dark ring where the case mouth sits like other rifles. I am measuring the chamber by having the bolt closed than measure the length of borescope cable that come out the muzzle until I am lined up with the marks. Not the best way of measuring.
 
I tried putting a 10-gauge brass brush soaked with bore cleaner on a cleaning rod connected to a drill. It did not remove anything that I could tell. I am going to do a little more research before attempting anything else.
