Home Forums Hunting & Shooting Ask The Gunwriters Borescope Usage

I don't buy anything from communist China! It's like buying from the Nazi's in 1940.

Factory barrel in 25-06. The extremely long neck area of the chamber allowed lots of hard baked carbon to accumulate over the years.....took a lot of effort to remove it completely. Using Lapua 30-06 cases sized down, the necks lengthened enough to bring them to within .010-.012 of the end of the chamber. The necks also thickened up .0015 per side which brought the neck clearance down to .006 instead of the .009 it was with 25-06 cases. Win/Win and it shoots crazy good for a factory barrel.

At one time I was a very serious Rimfire Benchrest shooter. I had a great shooting rifle that gradually went away. Turns out, I killed the muzzle end of the barrel with sloopy cleaning rod use. I cut off the end, recrowned and it went back to great shooting !!

Teslong had a new collapsible borescope at SHOT.

You might want to check out the history of U.S/German trade relations during WW2.

The U.S. supplied the Luftwaffe with specialized oils, Henry Ford supplied them with parts funneled through Ford's European factories, etc, etc.

'Economic Trade With The Third Reich' is a pretty good reference on this...pretty eye opening.

Thanks, Al.

Evidently we've had similar experiences with bore-scopes! But there's no doubt a Teslong (or similar digital model) beats the heck out of no bore-scope at all!

Absolutely! Most fixate on the chamber end, which is natural. But the muzzle is where a good percentage of the magic happens. Or doesn't.

It's like bullets. You can always tell if someone really knows what matters by which end of the bullet they examine first.

Notice The Inner Lives of Rifle Barrels is by-lined October but the cover date is November-December issue number 325 as correctly noted. While I'm picking nits the heading for Borescope Tested Handloads references 5 shot groups and the footer says group size is the average of 3 shots. Could be the average of 3 groups of 5 shot each or maybe not?

I have a Gradient Hawkeye with the right angle adapter and the high power light source because I like my toys and hate to be left behind. I even have a Hawkeye specific bore guide like a cleaning rod guide. Like wind flags I couldn't stand it if the guy down the highway has one and I don't. One of the TV cop shows used a genuine Gradient much like mine through a drilled hole to guide picking the lock on a gun safe for extra pride of ownership.

Sadly the directions didn't include enough to make me an expert on what I'm seeing no matter how many times I read the directions and look again. I'm in no hurry so all the chemical cleaning miracles work about the same for me though some do their magic faster and I don't play the is it clean yet? game.

A pro I know who can claim deductions for professional tools and equipment but has the professional's endless list of things he needs assures me a souped up MiniMag Lite is as bright as anything and he has learned to live with the slight color distortions of slightly colored bright light.

Clark,

Sent you a PM....

100 bucks from Amazon.

I have the flexible Teslong that plugs into a phone and the rigid MS450.


.223 Savage barrel: (by the way, very accurate)




For comparison, a PacNor barrel in .308 Win.




6.8 barrel with a few miles, still shot good.





I've used it to determine how well cleaning solvents work, of the ones I've tried, Patch-out does real good. These photos were taken after a post-shooting cleaning session.

That 223 looks like my Tikka 6.5 CM that shoots bugholes.

I'm beginning to think washboards is where it's at.

Never believe a borescope until you've put the gun on paper.

Got my back issue in the mail and reading MD’s article now

This is a pic from a 38-55 barrel that had about 300 rounds of black powder loads. I was using stainless steel pins to clean the brass at the time and I believe one of them slipped by me and made it into the next load. I went from shooting pretty well in that match to not being able to hit the target pretty quickly. The gouge was deep enough to pull fibers from a cotton patch. After this little incident, I bought one of the teslong scopes for myself.

😳😳😳😳

Thought stainless pins had no drawbacks. The total cats meow.

John,

I remember when you brought that rifle by our house, so we could look through the barrel with my Gradient Lens Hawkeye! It was pretty astonishing....

John

Ouch.....it pains me to see that, sir.

That's not the first time it's happened with stainless pins. It's just one of the reasons that I don't tumble or vibrate brass to clean it.
