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

Looks like pre-exisiting inclusions in the steel that were exposed by the re-boring process. In the second photo, looks like those inclusions were dragged along the bore surface, as well.

From the cut rifles.com Site

Barrels that often do not cut cleanly:
• Sako uses a type of steel for their button barrels that is unsulpherized, it cuts to a rough finish.
• Old Winchester barrels seem to have hard and soft spots the entire length of the barrel.
They often will have small tears in the bottom of the groove.
• Old Flaig barrels have a high vanadium content and do not cut cleanly.
• Hammer forged barrels occasionally have microscopic air voids created during the forging process.
• Ruger Stainless Steel button barrels.
• Mauser military barrels about a 50/50 chance of cutting cleanly.

As long as it shoots good don't worry about it.Mine didn't look all that great,but it's one of the best shooting rifles I own.

Looks like the cutter hit those then chattered for a little ways.
At first I was thinking galling, but the way it's laid out (at least the 2nd pic) makes me think the cutter traveled left to right. The chatter started after hitting each spot.

Husqvarna also doesn't cut cleanly because of how hard their steel is.

It's not just an '06 rebored to 9.3, JES rechambers to 9.3x62 after the rebore. 9.3x62 completely "cleans up" a 30-06 chamber, moving the shoulder slightly forward, so it's a good choice even if the headspace is excessive in the '06 - it gets corrected without having to set the barrel back.
I have one with him now and this has me wanting to borrow my friend's borescope when I get it back.
OP, please keep us posted not only on its range performance but on any comms you have with Jesse.

I can see why you might think that way, that reboring is a second rate option, but the available data do not support that conclusion. I did a fair bit of polling before sending my two rifles off to JES for rebore and the overwhelming majority of his customers have saved a ton of money, had no frustration at all, and gotten excellent accuracy. I have also heard from some who mentioned the barrels being actually quite slow to foul. I should have my rifles back in a few days and look forward to both eyeballing the bores and shooting them. I'll report back.

Instead of having us all guess, I would have first contacted Jesse and see what the expert says. I do know that most that do rebores say that some barrels do not “cut” clean depending on the virgin steel. My Marlin 30 AS rebore shoots great and although I never scoped the bore, looks and fouls just like a factory barrel.

Will do, what rifle is Jesse going to do for you?

I had those same gouges in mine when I received it back. It is a very old FN Mauser 98 and the bore was pitted pretty badly. Had him bore it from 30-06 to 338-06. I assumed the gouges to the lands were caused by deep pits that the cutter hit, but maybe not after seeing your pictures. The neck area was also a bit oversized. The bore doesn't seem to foul any worse than it did and the accuracy is around 1 MOA with handloads, which is better than it was before which was 3-4 MOA.

Two 1903 Springfields. One from 1934 with the full sized hefty original barrel that will become a 9.3x62, and an earlier one from just after the "low number" period. It was previously bobbed off to a 19" carbine and it's going to become a .338-06.

What's the SU35 significance? Does it refer to the FLANKER variant?

JES rebore usually shoots about as good as a new barrel and at half the cost. And the outward looks of the gun doesn’t change; the stock is unaffected.

Less work, less money and a good result.

My only question is, what type of borescope and how did you capture those images?
I want one.

Teslong Rigid Rifle Bore Scope, 0.2inch Gun Barrel Borescope Camera with 21inch Rod and 45° Side-View Mirror, for Windows, MacBook and Android Smartphone

And only $50 at Amazon.. Love mine.

Any borescope images before it was rebored? What did it look like?

No comfort to SU35 I'm sure, but I will still chime in with my "two bits". Sometimes what we don't know doesn't hurt us, AND the enemy of good is better! Kind of why I also despise mass social media and the "in your face" 24 hr/day news cycle... too much information that cuts down on the quality of my own personal finite life!!! No borescope for me... I suspect I would be "disappointed" with barrels much of the time.

As others have mentioned, go shoot the rifle and then make your judgement. If you are not satisfied with the performance, sell it and go buy a factory chambered 9.3X62 or spend the coin to build a custom.

I have had similar experiences with fishing/boating/camping gear, excursions, etc. "Less" is many times "more" when it comes to duplicating the joy I originally experienced with some of these pastimes. Gadgetry and` expecting perfection usually leads to let-downs IME. Everyone is different though!

Lundtroller, you have a lot of good thoughts there, but I have to disagree with the suggestion to sell SU35's new rebore if it does not shoot well. JES' rebores typically shoot well. This particular bore has some very demonstrable problems that may or may not be JES' fault. If it shoots well, then "pretty is as pretty does." If not, I'd bet money that Jesse will find a way to make it right. Because he has very, very, few post-rebore problems to deal with so I bet SU35's rare issue will get full attention. Still anxious to hear how the comms with Jesse go, and how she shoots.

And still standing by to hear the back story on SU35's "handle." Wondering if maybe we crossed swords some time in the past.

Don't obviously have all the information. Most likely not JES's fault... he has a good reputation. Not SU35's fault either. Just saying that if one's expectations are not met, realistic or not, just move on to greener pastures! Life is short.

When I had a conversation with Jesse, I remember him mentionioning several situations , ie. IIRC stainless barrels and those with the high vanadium content possibly making for difficulty.

I know I would JB it good and see what happens. I have never seen a bore that clean.....😎😎
