Anyone know of company that can rebore a 35whelen to 9.3x62?
      #278540 - 28/02/16 08:03 AM

I'm looking to purchase a rifle from a member that is in 35whelen, I'd like to rechamber it to 9.3x62, most the outfits I've called said they are no longer in buisness or taking work. Thank you

Gundog01,
Why in the world would you want to do that? Is the 35 Whelen shot out? I think you are taking a dandy caliber and turning it into something that is going to be hard to find components for and it will not perform a bit better than what you already have. Just my two cents worth. Bob

As a gunsmith and a former barrel maker I think I can answer your question.
#1 is the basic principal of building anything in business which is this;
Everything is about overhead, materials and labor

In making a barrel you have steel and machine time as well as some hand lapping
In a re-bore you have all the same things except the steel.

Ordnance steel today is selling for about $6 a pound so if your barrel has 3 pounds of steel in it, the steel is worth 18 dollars and ALL the rest of the cost is machine time and labor.
But in a re-bore you do not have the luxury of making the barrel long and cutting off the muzzle end to eliminate run-out of the tool head, which is how all cut barrels are done. So on a re-bore you have MORE set up and labor that can far exceed the $18 it would cost to start over.

The point is this;
Is there some reason you want to re-bore instead of replace?
In restoration work we often want to re-bore or re-line because of some historical significance.

Or if you have a barrel that is machined in a fancy way, ie. having a integral sight or rib, of some such other feature that you do not want to loose?

If not you will be FAR better off to re-barrel the rifle then to re-bore, re-chamber and re-rifle it.

So, please tell us about the rifle. WHAT DO YOU HAVE?

Acording to the highlighted text, you wish to put a 9.3x62 chamber in a .35 Whelen. The title, however says you wish to re-bore, coupled with the text, into a 9.3x62, not just what is literally an IMP .35 Whelen.

The IMP Whelen is the way I would go.

Many years ago, Scovil and a fellow named Hawke put a 9.3x62 chamber into a .375 barrel, making what they called the .375 Hawke/Scovil. This chambering actually gave the ctg. a 78gr. caspacity, which is larger than the standard '06IMP chamber gives. The reason was the slightly longer body and the .475" base diameter. The .454" shoulder of the normal 9.3x62 was already the same as the '06IMP case. I know that some scematics say the 9.3x62's shoulder is .451"- but 2 I have measured leave fired brass at .454".

I may be going off on a 'different' tangent here, but after developing this ctg. Scovil had another reamer made up which had the same case body as the 9.3x62, but was made with the standard .470" base so '06 brass could be used. This "new" chamber was called the .375 Scovil. It differed from the standard (if you will) .IMIP case by having a longer body, shorter neck, but still had the sloped 9.3x62 shoulder angle.

What I would do, unless that .35 Whelen barrel is crap, if wanting more 'power', simply go with the Ackley IMP .35 Whelen, or the Brown Whelen,(same as Scovil's) which will give you a 77gr. to 79gr. case capacity. THAT is a good round. There are no flies on that one. If you wish, the premium bullets available today in .358", are super good and will do/perform however a 9.3x62 would.

As to a re-barrel, many years ago, this was very much cheaper than buying a new barrel and was highly recommended - today, as Steve noted, it can be just as expensive or more so than a new barrel. This was the case about 25 years ago when I was going to have a barrel re-bored and rifled. The price I was quoted was higher than a new barrel in the desired calibre, from the same gun smith - this was in Alberta somewhere.

Wash your mouth out with soap. Converting a 35Whelen to 9.3 is sacrilege.


I feel you will need to rebarrel it. Not many can and even less will rebore a rifle barrel. Sell the Whelen barrel if it is in good nick to help off set the cost of a new barrel or have the Whelen rechambered to 358Norma Mag.

I have a Gewehr 88 based sporting rifle, labeled Nowotny of Prauge, that I thought was in .35 Whelen but Kuduae suggested that it is in actuality a 9x63 Florstedt. Perhaps your rifle is also a 9x63 Florstedt and not .35 Whelen?

or have the Whelen rechambered to 358 Norma Mag.



That's sensible and you`ll end up with a better cartridge too!

I have to agree with Daryl S. If you reload, a simple rechamber job to 35 Whelen AI ( Ackley Improved) will approximate 9.3x62 performance and allow you to shoot factory .35 Whelen ammo.
If you want more punch then I would recommend rebarelling to .375 Ruger which can be loaded to 9.3x62 levels or slightly better than.375H&H. This would be equivalent in cost to reboring with a much better chance of an accurate barrel and would require standard opening of bolt face and extractor and a little rail trimming to make an excellent big game rifle.
If you must have a 9.3x62,which is my favorite cartridge, Rebarreling is a better option at similar cost. If you check out smiths who rebore you will see that they will not guarantee that the bore will not be damaged or shoot accurately. Also the .35 Whelen is longer than the 9.3x62 so there would be a step in front of the neck about 1mm long. Barrel could be set back but this would require glass bedding.

You can contact JES and ask them. Or you can google JES reboring and see what you think. Some guys on other forums have went through them and say it is worth the money.

Seems to me, the big problem with re-boring, is holding the old barrel contour properly, for boring, reaming and button rifling. If cut rifled, I still don't know if there is a problem with the re-bore and ream - but, have heard or read this is the problem.

A long time back, like in the 80's, I inquired about having a rifle barrel re-bored here in Canada - in Alberta was the barrel maker - I do not remember the name. I was quoted a price for my Chrom-moly barrel at $50.00 over a contoured, chambered and threaded, match-grade Stainless barrel from Shilen. I went with the new barrel form Shilen. This was before I knew about Pac-Nor. Their barrels are incredible shooters.

Daryl, speaking of prices I did forget to add that. The quoted price from JES is 225.00 (I believe) so you would not spend much more at all for a new barrel. I do agree that it would probably be a better option for just purchasing a new barrel, but I know some people who HAVE went the other route have had good results. And accuracy has been good after the re boring of the barrel

Here is a link to another forum I am on that goes into some of what took place with JES and the results of this individual. I know opinions may vary, but this is this persons.

Interesting thread on the .356 Win.
Just in case you are interested, mine did around 2,700fps with 180gr. Speers and 2,500fps with 220's. It was a Big Bore Win. 94 with a 20" bl. - best big game load was with 250 Horn. RN's at 2,156fps, went 1 1/2" at 100meters for 5 shot groups w/2 1/2X ScopeChief - 46.0gr. H335 & CCI250 - crimped with a Lee crimp tool for 2.55" OAL. Note - I flattened the noses as well.

Thanks Daryl. I thought it seemed appropriate to post the link as it deals with having a rifle re-bored. I have thought many times of the .356 winchester. Daryl, hit me up with a pm. I would like to talk to you a bit about that rifle

I have an 03 springfield that wears a 18" 06 barrel. I have often thought of re-boring that one to the whelen myself. I like the extra thump and the larger wound channel it would offer. But again, after pricing barrels, it would be roughly the same price to just get a new barrel. But by the time you figure in a gunsmith, if you send it off, I think you will still come out a little cheaper to do it by re-boring. Around here, the prices range from 60.00 on up to chamber and install a barrel, but the extra cost of anything beyond that would add to the cost. In this instance of what the OP is asking, in all honesty I believe he would come out on the better end if he just installs a new barrel.

Of course, I was thinking on the re-chamber and threads myself - silly me. Yes, any required gunsmithing is indeed on top of the barrel price, without reamer or lathe.
