Curious if anyone has actually done a conversion of caliber on a ross rifle successfully?

I recently purchased a donor sporterized Ross after years of contemplating doing this.

I would really appreciate it if a Ross owner attempted to feed a .444 marlin or .405 win from their rifle.

If anyone has successfully converted a ross or enfield to a JDJ wildcat, 444 or 405 win I would definitley appreciate it if they shared their experience doing so.

If anyone can share gunsmiths involved in the process or give me a link to the guy in Alberta (or another canadian) who rebores rifle barrels I would appreciate it.

Thanks,

Conor
 
I would give Ron smith a call and see if he can do a rebore. I think a 375-303 would be pretty neat and relatively painless
 
Cheers, can you pm his number?

Trying to get some dummy rounds and see if they feed first. Might go 303 wildcat, before I get ahead of myself I’ll see how the bore is.
 
Conor:
Must be something in the water as you are the second guy to ask about this in 10 days!

I am presuming a MKIII military that you have?
The cumbersome mag is problematic to say the least for longer/larger cases.
If the reason you are doing this is a shot out barrel, may I recommend .35 winchester which only requires a chamber reamer and rebore of existing barrel.
However you are left with an overly heavy barreled "sporter" with the leftovers of a "bayonet handle" military stock;

May I respectfully recommend you spend your time and monies on an M-10 .280, shot out or not.
If not, you are instantly in business with a superb rifle, but if so, a new barrel and some fairly straightforward work on the bolt face and extractor head will get you all the way to where you want to go, say 30-06, 270 Rem Mag and so on.
These "hotshot" big bore cartridge mods kill on both ends, and usually end up in the back of the rack, especially as you reach my septuagenarian splendor (?)
If I had the time and ambition I would convert one of my lesser M-10s to .308 or even .223 and shoot surplus army ammo all day long.

Segway.......Have a look at an E-10 in (or it's lesser brother the R), .303 and if it is shot out do the .35 winchester thing and voila, you're all the way there!

If and when you get serious PM me and I will send you a couple of pics of my Sedgley M-10 in 30-06.
Good luck in your endeavours.

To my knowledge the only variations from .303 in the '05s and E and R-10s was .35 Winchester.
I did a quick look in The Ross Rifle Story to stand corrected, but can see no reference to .405.
Could you give me a reference as I have never heard of this in some 50+ years of collecting Roand I would be MOST interested,\.
Thanks

OGC thanks for your response.

I have already pulled the trigger on a heavily sporterized r10 (I believe?).

I have heard of conversions of enfield to the jdj line of wildcats and .444, but have never seen anyone go in depth on it besides "it's easily done". I'm kind of in "prove it" mode now. I have also heard of 375 nitro express 2 3/4 working well.

more pictures when it arrives.

My intention is to refinish the stock, and apply a new british style red recoil pad myself.

I will reblue the barrel and action and possibly have the bolt case hardened.
 
Tiriaq reported that the barrel shank is a very odd thread. He recommended (based on first hand experience I think), boring out the existing barrel shank and inside threading it to something more modern and accessible. Then you'll have your choice of diameters, chambers, and twists without trying to broach 100-yr old steel.

If you know how to thread, it’s not hard. Just square.

The 1905 - standard Mk. II - has the unusual thread. 1910 - Mk. III - has the conventional square thread as shown in the diagram.
Mk.II** has a square thread, but I've never seen a shank, and have no idea how similar it is to a 1910.
 
I have a couple that have been reworked one has had the barrel rebore to 35 so is a 35/303 and one in 6.5/303 imp, this is the 6.5 and from my understanding was built by Epp's when they were in Clinton about 1957 or 58
It has been restocked since it was built
