.308 Ross?

Ever shoot the rifle, or track down the owner, Cantom? If he shot in Ottawa, the DCRA office has all the competition records, would be interesting to see how well he did with the rifle.
Boltface and extractor wouldn't be problems with a single shot conversion.

Sorry to say, no to both.

As I recall, it did head up to the Ottawa area after I had it.
 
It would be a lot easier to install a 308 barrel and chamber it for 303. That way bolt and mag are fine.
Check out the Confederate Sabre line of cartridges based on the .303 brass using easily available common dies some shortened some not in the case of the 7x57 it is used as is.

If it’s ammo price or availability - why not do as the Russians did and convert the Ross to 7.62x54R?
 
Or the 7.62x53R with a .308 barrel? Any of the 7.62x54r bullets I've pulled were .308 in size? So maybe that wouldn't matter.Thoughts on that Ganderite?
 
The rifle that Cantom pictured, is in my collection. It was built by Eli Campbell and Sam Adams of Turo NS. I spoke to Sam Adams and he remembered the rifle, he did the metal work and Eli built the stock. The rifle was shot out to 600m and I spoke to a guy on here who had shot and said it was a good shooter. I have shot it at 200m and can say it works well, I should get it out as it has been shut in for a couple of years.

The 7.62x54R ammo I have pulled used 310 bullets.

I would think that the cost of doing any re-barrelling or re-chambering would cost enough that the rifle should be used for more than just a milsurp shooter.

I don't know what the bore and groove dimensions of a Ross is. The used 308 barrels i use for this kind of project are about 307 to 3075, so i would nto want to shoot a 7.62x54 in it.
 
Mk. III (1919)? Action is strong enough. Boltface is set up for the larger rim of a .303, so that would have to be addressed. The magazine would also need attention.

I have often toyed with the idea of re-barreling a Ross MKIII or my shot out R10 into 7x57Rimmed or 7x65R. There would be no boltface issue with either of these cartridges. Maybe some attention to the magazine feed to account for different case taper as opposed to the 303Brit, but that should not be too difficult.

quite true Ganderite.
If one were to re-barrel with a new .308 bored pipe and use a 30-06 chamber reamer, I think it would not be a huge stretch to then use 7x65R brass loaded with 30cal bullets and you have a rimmed 30-06 of sorts. Maybe I am dreaming in technicolour but I wonder if anyone has attempted such a thing??

Would a longer rimmed case fit the magazine? And where would you source the brass? The #1 or #4 action is hard on brass, so the cheap solution is to use the 303 case.


If I was going to buy a reamer, I would toy with either a 6.5-303 or a 35-303. A 358 Brit would be an excellent hunting rifle.
 
Around 20 years ago there was a fellow in the Fraser Valley that built up a 7.62x51 Nato on the Ross platform MkII, with the single solid locking lug on each side of the bolt head.

I first met the fellow at a HACS show in Renfrew. I had a box of assorted Ross parts that weighed close to 30 kilos. I had been carrying that stuff around, from show to show for over a year. I traded him the whole box of parts for a sporter MkII.

I really wish I could remember his name. I can still see his face like it was yesterday, but I lost the associated name, along with others after a bout of chemo. He looked to be in his late fifties and lived in the Chilliwack area.

He was particularly pleased to find several bolt heads and extractors in excellent condition for both the MkII and MkIII types.

He reconfigured the bolt face by getting the face welded to add metal and then Harry Nicholson machined the face to the proper dimensions for the 308 Win. He was a tin basher and had modified a magazine to accept an feed the 308win case. He commented that his biggest problem had been getting the cartridge to feed from the box and up onto the ramp reliably. The rails and ramp were designed to accept the tapered body of the 303 Brit.

He was very motivated and excited about the project.

I saw him for a couple of years after that, only at the Renfrew location. The rifle was supposedly completed, after a two year ongoing basis.

After welding and machining, he had to get the bolt head re heat treated. I seem to remember he had to send it to the US for that. The same was done with an extended extractor.

Then, he just didn't show up any more. To bad, I've wondered, on more than one occasion what happened to him and his interesting project.

The strength of the actions is well documented. PO Ackley really liked them and tested them. I believe they were right up there with the 98 Mausers.

The Russians built up Running Bore match rifles on their surplus spares, based on their 7.62x54R.

So no fears about strength.
 
With my Ross long range target project (which you can follow on the target and precision forum) I considered heavily what caliber I wanted, and I read threads like this over and over.

For any rimless cartridge, the necessary modification would be to add a spacer in the bolt face for the smaller diameter of the rimless cartridge. Additionally, the extractor would have to be extended inwards to grip the smaller rim. Additionally, an extended flat on the underside of the bolt may be required to feed a smaller cartridge from the magazine. I really wanted to do the build in 6.5x55, or something on the 308 bolt face, or even 7mm Rem Mag, but with the aforementioned modifications, I decided against that. I instead decided on doing. 6.5/303 British since it would provide the same ballistics without bolt face modifications (and a friend had a reamer). My donor rifle is a .280 Ross M10, so I will have to do some minor magazine work, but not much else I hope.
