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

Get a NECO Fire Lap Kit, use the cheapest 9.3 bullets and fire lap the devil out of that thing. Then shoot a box of factory loads ( PPU or something) Just use a Bore snake and EezOx after that fr cleaning. If you get 2" and under, you will kill everything you point at in range! Have a ball pard!

Did you take any pics before it was sent to JES? It looks like the inclusions may have been there and the rifling tool caught on them as it passed. Not sure reboring could cause these inclusions 90 degrees from the bore.

My 38.25" scabbard scout rifle was rebored to my 41 O&M wildcat cartridgeby Jesse. I use this all winter for caribou and spring grizz by dog team

Firing 350 grain copper jacketed swift A-Frames at 2400 fps, copper fouling developed quickly.

It was easily removed with 10-15 passes of kg2 on a 45 caliber bore snake.

It is too fine to tone-down tooling marks. It only removes copper.

320 grit compound(Wheeler enginering kit) on the 45 caliber bore snake worked perfect. No change in accuracy, the thing stacks 41 caliber bullets like robin Hood with arrows. It just cleans up quicker.

In the picture, you can see my 41 wildcat next to a 30-06 cartridge, what the browning 1895 was originally chambered in.

Love the pics and info

My two new rebores from JES arrived this afternoon. I'm going to borrow my buddy's borescope tomorrow and look 'em over. I'll try to capture pics and post them. Squinting down the bore looks OK.

This is the image found via the first link that concerns me the most.

No pics taken before being sent to JES as the Ruger bore was normal looking.

That certainly is disconcerting!

And disconboobalated.

I just finished looking all through the two new JES rebores that arrived yesterday with my friend's Teslong borescope. There is nothing like the issues SU35 posted in his OP. The short barreled rifle that went from 30-06 to 338-06 was a real sewer pipe pitting wise before the rebore. There are some places where I can see the .015" taken off in the rebore did not clean up the pits entirely, but there are no apparent mistakes. The 9.3x62 having had twice the amount of steel taken off, is very clean and shows no evidence of pitting, but I found three small boo boos all of which were along the same side of one groove. They are all pretty similar and look as if the cutter slipped the same way three times in one pass. Everything else looks just fine.
Hopefully the pics tell the story. Three pics of the three gouges found in the 9.3, one pic of what both bores typically look like, and one pic of the only short section of the .338 I found where it looks like the rebore did not get all the pitting cleaned up.
I remain of the opinion that there was something like inclusions in the steel itself that led to SU35's issue.

Actually I am not surprised by your results.

Ruger metal tells the story here.

Reminds me of the day Ruger supplied Badger barrels for the Palma team rifles.

That was a disaster for the U.S. team.

Looks like gauling

Dull broach or double cutting chips and or poor lube during the cut

Firelap and shoot, shoot, shoot. Be Well, Rustyzipper.

Well we're still all looking forward to hearing how your rifle shoots, SU35. It wont surprise me if it does just fine, especially after having been shot a little bit. I've got high hopes for mine. I have a bit more to do to the 9.3 before I'm ready to shoot it, but I have the .338-06 is ready to shoot. Maybe I'll get to the range tomorrow!

tedhorn, are you talking about the images I just posted on the ones SU35 posted back on page one?

Cheers,

My thoughts as well considering the spots are right next to the groove, and all on the same side. Dull tool that is tearing instead of cutting.

Haven't cleaned my 9.3 barrel yet, but removed the copper from the .338-06 with WipeOut and gave it a few passes with KG2. Now there is no sign of what earlier looked like pitting that failed to "clean up", nor that small section on the edge of one land that looked a little "crumbly", which I had also attributed to vestigial pitting. Everything I can find anywhere in this bore now looks like this. Going to clean up the 9.3 now and see how it comes out.
Cheers.

Too much information can be as bad (or worse) than too little information... the whole borescope thing falls right in the middle of this reality.

Take it out, shoot it, move on.

I sent them a Savage 99F in 308, it returned as a 358, shoots better as a 358 than it ever did as a 308. I can complain with their work and they will be getting some more when I find another deal.

I'm not sure if you're talking to me or SU35 (or both of us) but I agree 100% and have every intent of doing just that. I just got back from the shop where I free floated the .338 barrel, and mounted a good old Leupold 4x scope. I'll get a new red Old English Decelerator pad on it this week, replacing the old thin White Line pad, which will bring it right up to my proper length of pull, and ease the kick a bit on this light 19" carbine.
Once it's proven itself on the range, I'll finish cleaning up the outside of the barrel (it was pitted worse than the inside), bead blast and blue it, and refinish the very nice walnut stock some long gone 'smith made for it back in the day.
I sure hope I did not give the impression I am unhappy with this rifle. On the contrary! It's been sitting in my closet for 15 or 20 years waiting to become something new and go hunting again, and I'm glad to finally be doing it, not just for this rifle but for 6-9 others waiting in the queue. It's ironic that I spent my adulthood building up a backlog of projects to complete "one day" and it's not until I got retired that I can finally get to it. But that leaves me with more potential projects than I can ever hunt with until I'm no longer able.
I'll post how this .338-06 does and look forward to hearing how SU35's shoots.
Cheers,
Rex
