I heard about this cartridge recently, but can find absolutely no information on it. Does anybody have some info they can share? From what I've gathered, it is a .290" bullet, but what is the parent cartridge? Has anybody built a gun a gun for this cartridge? If so, who and where are they located?

Any help would be appreciated. Thanks.

There is mention of this cartridge in the July Barnes newsletter.

Call Clymer--they may have a print of the reamer/chamber. I recall making a 290 Askins reamer for Joe Dubiel in the early 80s. Also made a swaging die reamer to reduce 30-cal bullets to .299"/.298". Don't remember the parent case, but it could have been 8mm Rem Mag or 308 Norma.

Seems like I remember old cheerless charlie Askins doing this for a lark, he said that was the only caliber space left to work with. he did the whole shebang up for an article, I dont remember the parent case either.

I remember an article back around the mid 80's about what would be the "perfect caliber" round. It would fall between 7mm and 30cal and if I remember correctly the bullet weight was like 178grains or something like that. Even in my youth the article sounded like something they came up with to fill up a magazine one month. Is this possbily where this came from. I'll bet somewhere I still have that magazine. I didn't remember it being Col. Askins but someone like Claire Rees or someone like that it GUNS mag. ?????
