Ross Rifle Co. M-1910, .280 Ross

[longbranch*]

.280

You know the more I think about it, I dont think you owe your buddy much more than big "thanks" and a couple of pints maybe. Saved him from dealing it on the 'net or drag it to gunshows. I'm sure a gunshop wouldnt have given him to much more as they have to at least double their money to make it worth while.

ive never done it myself, but if you reload, the word is you can make cases from 7mm mag.

Sorry, have to disagree with this one... the cases are completely different. The Ross is a semi-rimmed design and is wider at the base than the 7 mag and slightly longer as well. The Ross uses a .287" bullet according to cartidges of the world. Handloading is your only option; factory ammo hasn't been available for ages, is probably unreliable after all this time, and you'd have to pay collectors prices for it.

I have a gunsmith friend who rebarreled one of these to .300 H&H for his own use. Not a recommendation, or even a suggestion, but he doesn't have any qualms about shooting it.

Cases can be formed from .300H&H. It is usually not necessary to remove the belt. .284 bullets may work just fine. It will be necessary to try them.

There is a lot of misconception about the .280 Ross dimensions (a.k.a. .280 Rimless Nitro-Express Ross as per CIP).

This is a drawing from the Winchester Repeating Arms Co, from "The Ross Rifle" book;

One day, a wrong drawing (originating from a very bad conversion from mm to inches) showed a base diameter of 0.549", but with the correct metric dimension of 13.59mm, then everybody became confused about the right dimensions. I even saw a recent US publication reproducing these wrong dimensions... two little research from the author, maybe?

CIP's drawing (which I can't reproduce here) is the same.

Base diameter P1 ; 13.59mm (max) / 0.535"

We, .280 owners used belted magnums in the old days when nothing else was availlable. It didn't make a cute case with the massive bulge in front of the belt, but it kept the .280 working.
The smaller rim thing is, most of the times, a non existent issue and if it occurs, it can be avoided by using a standard .303 Brit extractor.
