Home Forums Hunting & Shooting Hunting Rifles JES Work... Bore Scope Images.....Revealing

I don't see JB cleaning up those potholes. They are a big deal. Unless they are not and the rifle shoots great. The answer to which, we await, along with the provenance of SU35's handle.

FLANKER-E My son's idea when he sat on my lap when I joined the club here some years ago.

Best answer so far, I think.

I have no doubts about JES work unless he tells me different.

This was a brand new bore and had no seen glitches in it when inspected before being sent to JES.

First bullet down the bore for accuracy testing will be a 250 AB.

I also think it's more of problem with the Ruger steel than his work. He's done three 9.3s for us so far, two stainless Model 70s and one Ruger No. 3.. I got a teslong recently and so far I've checked out one of the Model 70s. It doesn't have anything like the OP's Ruger barrel. Nonetheless, I suspect it will shoot just fine. Both the Model 70s I have shoot great. The most used one will put 10 286 partitions into an inch at 100. The other is my son's and hasn't been totally evaluated yet. I have yet to examine or shoot the Ruger No. 3. Anyway, I suspect things will be just fine.

Currently I have another Model 70 with Dan Pederson being re-educated from 7mm mag to .416 Taylor. I'll let the tribe here know how that goes when the time comes, but after much research and a fair bit of experience with various and sundry jobs from JES I've reached the conclusion that reboring is a sound choice for a new barrel.

I've got relatively modern barrels that have seen hard extended use in wet weather that look 100x worse than that, mild pits everywhere, and they still shoot MOA. Not what you'd want if you'd dropped $800 on a new barrel and rechambering, but for $250, I wouldn't sweat it. Machine work to me looks good. Better than lots of Remington factory barrels. The fact that there was an inclusion seems like luck of the draw.

The best thing is to buy a borescope and use it to look at guns you've used hard for 20-30 years. A lot of the time they look terrible under a borescope and meanwhile the reason you've kept them so long is they shoot great!

My conclusion and I would send JES another rifle for work no problem.

He cut rifles his barrels by the way.

Looks pretty clean as is.

JB won't affect those inclusions, those voids in the steel.

Sometimes a bore scope provides too much info. If it shoots like I think it will and if you'd never seen those voids, you'd think it was great.

Need a range report.

Buy a borescope and look at other peoples guns. Leave it out of yours!

Hopefully by next Thursday at latest.

Good point. A borescope is to solve problems, not create them...

It provides info, isn't the ultimate end all. That info has to be calculated into the over all picture, does not represent the total picture.

A new borescope owner needs to be aware.

The final exam is at the range.

10-4 on that

That ah spirit. Good words for our man, Jesse. Like i said before, a little bit of bore polish will go a long way. I'm betting as is, that rifle will shoot better than you'd imagine. I take a bore snake 3-4 calibers larger, coat with 320 grit lapping compound and pull through rebore. It'll tone down tooling or steel imperfections. Usually 10-20 passes. It'll cut down on fouling.

or maybe you sent him a piece sheet gun azzwipe

Thanks guys for the info.

Just bought one...

Yes a bore scope can open your eyes so to speak. Can also cause heartburn.. Overall to me worth the money for the Teslong. It will let you know where your cleaning regime is at and condition. Looked at several of mine, an old Mauser 98K with the original barrel. Looks like a sewer pipe.. Still shoots as good as I can with irons. Winchester Model 70 finally saw why it did not shoot well. Tool marks from hell. Was going to buy a Schultz and Larsen in 7X61, looked at the throat with the Teslong. Alligator skin.. Saved an issue later there. To the OP looks like the issues were in the barrel steel. Shoot it and see.

Looks good.

If I didn't already have an $800 Hawkeye, I'd get one.

I'm thinking you really can't clean a gun if you can't see what you're doing. Watching blue patches doesn't reveal enough to suit me.

If you don't have a bore scope, get this one.

Maybe a group buy discount on that bore scope?

Call the manufacture: tell them them youre trying to get the "24 hour campfire dick-move bore scope discount".

That you'll post the jess rebore images on a national public forum, before you've even shot the rifle.

I have that same bore scope but it doesn't provide a view as sharp as yours. I've been wondering if the semi-rigid cable model would work better.

In 41 years in the engineering field I learned one lesson. "Don't fully trust a photo" A photo is only a start to an investigation. The mark in the photo looks like a common chip relief from the cutting tool. The chip gets progressively hotter towards the end of its length. The hotter material will be harder and lift the cutter. I would bet that the deviation is within the dimension tolerance band.


I have several old Russian military guns that have barrels with thousands of flaws like the one in the photo. All they cared about was would it kill a Bolshevik

SU,

I could see the initial alarm with this. I once got a steal of a deal on a brand new stainless shilen barrel. The smith bore scoped the barrel after it was installed and ready, and we were appalled by the condition, pits etc similar to the pictures above.

Long story real short, it shot flawless. Cleaned slightly harder, but groups were around 1/2 minute with little work when I did my job.
