On a Rigby !!!! Oh hell no. Hornady loads .275 marked brass. And Hendershots Sporting Goods https://hendershots.net/ will mail you their Extreme loads with correctly marked brass and with any bullet you desire. They load for my .275 Rigby.As above, expecting a government official to know that they are the same is expecting more than I'm willing to chance.
If it were me and I absolutely needed to bring that rifle, I'd have it off to an engraver to have "/ 7x57" engraved after the "275 Rigby"

In which case a / 7x57 on the barrel might not be such a bad idea after all - apologies to Bert. I have a Rigby, and Hendershots loads things in properly marked cases that the little rifle loves.
1. OK, before blood is drawn here, be sure we are talking about a Rigby .275 Rigby and not the Ruger African Rigby .275.
2. If you go with the Hornady .275 Rigby for either rifle. I suggest you fire up what you buy and then reload the properly marked cases. I initially used these in zeroing my Ruger Rigby and had many problems with them, including many misfires. After trial and error, I now only shoot the Nosler 7x57 Mauser in that rifle, but if I were to take it to Africa, I would follow the advise I gave you.
I would give serious thought to adding a caliber engraving on the Ruger Rigby, but agree with with RedLeg completely, Hell No on a true Rigby!
No misfires box 1. Five misfires out of 9 or 10 rounds fired out of box 2.Just so I'm not misunderstanding you. You had "many" misfires with Hornady factory ammo in .275 Rigby marked ammo?

I should add that I have and still do shoot a lot of Hornady factory ammo in .300 H&H, (the most accurate of any ammo in this caliber), .375 H&H, .404 J and and .416 Rigby, and have never had a misfire with any of those.
Bad batch perhaps. Never heard of that many misfires in factory. I don't think I've ever had a single misfire when I was using factory.
You are correct, 7x57, 7mm Mauser and .275 Rigby are the same.I am of the opinion that a 275 Rigby is a 7 x 57 by another name, and that the ammo regardless of head stamp can be fired in either one. Am I wrong in thinking that this 100 year old dilemma is not exactly new news? I'd like to see riflepermits.com weigh in on this one.
