Here is the contact page for John Taylor.

Contact him. He is a no frills, no BS operation and a darling among the the single shoot crowd. He did a number of rifles for while I was overseas both liners and barrel installs.

Here is the TJ's info.

Not sure if it has been suggested, but it would be re-bored and rifled to a .338 or .358 calibre on the .303 case - improved or not - your choice.
I'd contact a barrel maker in the States and ask if they do re-bores and if not, will they suggest someone who will.

Ken Waters has had more than one shot-out .303 re-bored, one to a .358 on the .444 Marlin case. I'd stay with the .303 case, myself.

Thanks DD! I'm going to drop these guys a line and see what I can do. Now I wish I'd kept my old No.1 with the pitted bore so I could try an 8x50R and a .338/.303! Wait. I guess being British, it should read .303-.338.... Anyway. This has been a big help Gentlemen. Sometimes you just got'ta knock things around a little before you can put them together. I'll keep the forum posted about what I find out and where I head with this. Would love to hear about any of the other members who have tried some of these options, and see the fruits of their labors. Best to all Norman4.

I'd have it rebored to .35 cal on the 303 Brit case.
Simple and requires no alterations to keep it feeding & extracting/ejecting.

I had a BSA Lee/Speed done over to the cal and a (Watson Bros) Martini Sporter also. Both had burned out .303 bores.

JES Reboreing did the work for me.
Excellent work, more than fair prices and a fast turn around of a couple of weeks.

http://www.35caliber.com/

I loaded the round on 35Remington dies which I already had .
It made excellent shooters out of a couple of sideways lead throwers with little effort.
Not quite as classic sounding as a .375 whatever but they worked just fine.

He can do a .338 or .375 on the 303 case too.
.35 just seemed a good fit as I had a good supply of bullets already from my 35 Remington and Whelen shooting.

Call Jesse. Leave a msg if he doesn't answ,,he WILL call you back.He doesn't always hear the phone ring with the machines running.

I'd second the suggestion to go with JES reboring. He did a Sedgley Springfield for me that had a bad bore. I had the rifle back in 10 days. He went from 30-06 to 375 Whelen. Jes recommends .200 over bore size for a minimum diameter at the muzzle. With that in mind a .375 would require a minimum muzzle diameter of .575

I would look at any of the wildcats on the 303; .338, .35, 9.3, .375 or even .411. All would be excellent choices. They all would be easy to make from standard 303 brass and CH-4D will make dies very reasonably, if they don't already have them in stock. They have a great variety of wildcat dies.

The 9.3x303 might be a fun wildcat to play with. Should run close to 9.3x57 ballistics and be a real fun round. The 375x303 with the old Hornady 270 grain round nose would make a real thumper.

Good luck with your project.

Ken Waters did a .375 on the .303 without increasing the shoulder diameter and did this on a Ruger #1.

I'd be inclined to think in terms of an improved .303 case shape, for the case longevity increase straighter cases are prone to provide and for the improved case capacity & performance in the #3's and #4's.

In a re-barrel, the .270/.303 was popular in Australia for a time and included factory ammo thus head stamped.

Quick Q: Double D recommended relining to 303. I thought this wasn't advised for higher pressure/power ? If this is ok, would it be fine relining a 6.5x53r, if things are kept moderate (factory ballistics)?

Cheers.

Relining weakens the rifle? Is this true? I would think the liner would be made of much better quality/stronger steel than the original barrel. I would not think the installation of the liner would be any less invasive to the strength of the weapon than boring the barrel open to, say .358, and removing so much steel. Can anyone explain this to me? Norman4

I can't answer Norman, but i did see someone had relined their 30-40 Krag. I think this is about the same pressures as a 303 or 6.5x53, so i assume it's fine?

No relining doesn't weaken the barrel. You have a liner made of modern steels, if memory serves, 4140 from TJ's, often times much stroger than the original barrel.

ReLining isn't for every gun and I suggest it only for maintaining the original barrel profile and markings. Same for a rebore, except the caliber markings need changed.

Most barrel makers can and will duplicate your barrel for a price of course.

I have back in the olden days had a number of guns rebored for customers. Never seen it make a bad barrel shoot better. A good barrel that shot good and got shot out seems to continue to shoot good rebored. In the end the cost of a good rebore seemed to equal the cost of buying a new barrel and installing it. Reboring seemed to be the way to go in the days before we had so many good barrel makers.

Well, I keep leaning towards relining to keep the rifle kind of "original." It also simplifies the loading process for me as far as reloading .303s. If the price begins to climb towards the price of a new barrel that might be an issue. Of course, a new barrel would require fitting of the sights, barrel band, and bluing. What a conundrum! A savage axis in 30-06 wouldn't cause so many headaches! Of course if I didn't want to drive a Cadillac I'd buy a Chevrolet. Norman4

Exactly my thoughts for the reline - saves refitting the sling mount, and sights. And you get to keep the barrel markings (proof stamps, makers/retailers name, etc.)

Yes. Keeps the soul of the original.

I think this tread may help you on the 338/303 looks good other than not a factory Cal.

At least some solid info. Thanks Sarg.

Yes , That is my rifle in 338/303 . JES did the reboring on the rifle and a most excellent job . Reloading in simple : I just put a 338 expander in a 303 neck size die and used standard new 303 cases ( headspace is exactly the same as a 303 British case) . For seating I just used a 338 Federal die ( works fine ) I am the process of getting custom dies made in 338/303 Nitro Express. Puts a 200 grain Hornady interlock out at 2,200 - 2,300 FPS depending on your load of 4064

I enquired on relining my Lee Speed before re-chambering to 338/303 Nitro Express and no relining outfit or gunsmith would take the job for this very reason . It would have to be custom because relining companies stick to lower pressure jobs. The JES re-chambering was quite simple :the bore was just drilled out to 338 ,the 303 head-space stayed exactly the same with the 338/303 just a different bullet . The same thing as taking a 25-06 and re-boring it to a 30-06 ....Interestingly after re-boring I fired a box of 303 British Winchester hunting ammo out of the rifle to obtain the brass with no ill affects ( remember the headspace is exactly the same ) The groups with the 303 Ammo still hit into a 6-8" group at 100 yards with some keyholes but was no worse than the original shot out 303 bore . My 338/303 reloads in the new bore shoot cloverleafs now at 100 ; quite an improvement over the original !
