Interesting debate amongst some of the cartridge collector types, about the 7x57 vs 275 Rigby. Apparently Rigby built their guns with a different sized groove than std .284. And apparently, there never really was a "275Rigby" proper. The 275 "high velocity" such as the ammo pictured above, morphed into being called the 275Rigby. There was a debate on that subject on AR last week, under medium bores. That was pretty much what I got from it, anyway.
Hey .275 Rigby fans...

You seen Prophet's stock blanks? These could wind up as very nice (though pricey) rifles.

I've got a 1912 Mauser Model B in 7x57 that spent almost 80 years in Rhodesia. As it's quite old, I load for it with some care. But even shooting 140gr bullets there is no way on earth that I could get anywhere near the 2900 fps claimed on this thread.
The fastest 7x57 load in the Lyman book is 2898fps for a 139gr bullet, over 41gr of IMR-4320.
If you really want a 7mm bullet to go so fast, why not have the suitable cartridge - the 7mm RM?

I have owned several 7x57 rifles of modern design, and have achieved 2900 fps with the 139/140 grain bullets in every one of them.
My #1AB Ruger would make 2900 with the 150 grain bullet without shortened brass life of loose primer pockets.
The idea with these loads in the 7x57 is not to challenge the 280 Rem or the 7mm RM, but to exploit the true potential if the fine 7x57.
If you choose to load your older 7x57 to lower levels, be my guest, but don't criticize those who choose to load the 7x57 a bit warmer.
Regards, Dave.

Just so I understand, you can interchange a 7x57 and a 275 Rigby? So, if I bought a Ruger 1-A, I can use either "type" of cartridge?
Sorry if I sound "thick".

correct 7mm mauser= 7x57= 275 Rigby or should be.
There was a lot of variation in the original Rigby rifles. Some will have Rigby .275 High Velocity engraved on the receiver ring, other's will have " sighted for Rigby's special High Velocity .275 bore cartridge" on the barrel. Some were sighted for the original 173 gr. load. Even when the rifles were first produced, it was considered interchangeable with the 7x57. "Karamojo" Bell used German DWM ammunition in his .275 when he was out shooting elephants. So yes, while technically there was never a rifle with ".275 Rigby" engraved on the barrel, neither was there a rifle engraved with ".416 Rigby". They were always "Rigby's Special .416 Bore for Big Game", but the cartridge is still referred to as the .416 Rigby. Most of the rifles will have "Not English Make" stamped discreetly under the action and barrel, indicating they were barreled actions purchased from the Mauser Werke. Stocking and sighting was done in England.
As an aside, looks like I'm going to have to start saving my pennies for one of the Ruger No 1's. Very happy to hear they won't have that stubby little 22" barrel.

These rifles won't be too long now, looks like. Once we have the final specs(mainly the wood) and pricing from Ruger, we will start selling. There will be 100 avaiable, although we may sell 10 or so into the USA market.
