1905 Ross

Ok update time

I've had no luck on the machining a new barrel shank so the next question is how do I go about sleeving the old barrel shank


I'm thining of using an old 6.5mm barrrel and going with a necked down 303. Shank is only .900" and I need enough meat to ream a chamber

so is the barrel threadded into the shank stub or soldered and pinned or what ???

I have never done this particular job, but I would thread the new barrel into the shank. First thing I would do is have a look at the shank and thread diameter of a Remington 760/742, and see if this size would work. I've fitted a new barrel to a Remington barrel extension, and the diameter is pretty small, compared with a bolt action rifle. The .303 based wildcat is smaller in diameter than anything with a .468" head. This would give more wall thickness.

The Dangerous Cooey Carcano had the original barrels chopped just ahead of the chamber, then the remaining stubs bored out the threaded full-length. Then the Cooey shank was threaded, turned in, anchored into place with a set-screw in the bottom of the stub, and chambered. Sounds silly but it worked fine; no reason not just to copy.

BTW, the 1905 Ross action was rated at 100,000 pounds safely. By actual measurement, it has 40% more locking area than a 98 Mauser and 100% more locking mass. I have measured it.

The 1910 Ross action could not be demolished at the Ross factory. The powders they had available at that time could only get them to 125,000 pounds pressure..... and the thing held together.

The 1905 Ross action was the development test-bed for the .28 Ross cartridge and for its further development into the fabulous .280 Ross.

And there is an idea: working pressure on the .280 Ross was only 62,720 pounds (28 long tons) and you have that huge casing to work with. Turn the belts off .300 Win Mag, neck to 7mm and either taper them for a rimless Ross round or leave them straight for a beltless Remington Magnum. Action will handle it.

Ross DID chamber the 1905 commercially in the .35 Winchester. Uses .357 - .358 slugs, as Buffdog pointed out, RCBS makes dies and brass is easily formed from Hornady .405 Winchester cases.... and it is one of the true Monsters. NO bolt work necessary and the back end of the chamber cleans up nicely on chambering, the .35 being based on the slightly-fatter Krag casing. Marvin the Moose doesn't have a hope in Hell. And it's original, too!

Hope this helps.

thats what I was thinking of doing but with only .900" to work with I thought there was not a lot of wiggle room. Do you have specs or drawings that I could look at?

If I could find someone that could turn a 3TPI LH buttress thread I would have gone with the 7RSAUM its not belted and the bolt face is the right size. Feeding might be an issue but it would be a fun little gun.


Oh and I've been given a line on another 1905R ross in 303, I have to go take a look at it but it has a broken stock at the wrist that has been repaired with a big metal strap. I should get it real cheap, so all is not lost, perhaps I'll end up with enough parts for one in original configuration and one as a project.
