Some one asked me if their were any .290 caliber.

I said beats me so I am asking you guys.

Are there 290 caliber wildcats.

Charles Askins .... maybe. I think he did just because there was no 29 cal. He swaged down .308 bullets.
I also may be remembering it wrong!

John Barsness did an article on a 29 caliber wildcat, called the B-29. The article was the April issue of Handloader or Rifle, some years back.
It got the attention of a lot of readers..

Yup, all satire, with no actual 29 caliber round, if I recall correctly.

Yep, satire. As an April 1st joke.

As I have said before; every time I came with a new cartridge idea that was neater than sliced bread I would pick up my P.O. Ackley books + find out he did it 30 years before. Satire or not I see no use for a 29 cal. 28 + 30 will do everything you need.

there is, however, a .49 caliber -- you can order them from McGowen - I own the tooling, and this is no joke.. not a single measurement starts with a 0.5 ... 0.498 grooves, 0.490 bore ... and yeah, it works

In the early '80s we made reamers and bullet swaging dies at Clymer for the 290 DuBiel. Joe Dubiel and Charles Askins Jr. teamed up on this one; don't remember if I ever saw it in print.

I believe Askins wrote it up in the American Rifleman. I know I read it somewhere. Done mostly just to get an article out of doing it.

I went to a steel shoot back in September, there was a guy there shooting what he called a .296 magnum.
Bore diameter .290 groove diameter .296
This guy makes his own bullets by ordering .308 J4 jackets from corbin then swages them to .296. After the lead core is in he forms a bullet nose that looks a lot like a Berger VLD.
His finished bullet came in at 203 grains with a claimed G7 BC at 330 .

He was using the 300 wsm cases, nothing fancy just run of the mill Winchester brass.
This guy finished 3rd out of 40 shooters.
The rifle was based on an Impact precision action, McGowan barrel, KRG chassis, Jewell trigger, Burris scope.

The guy that won the match shot a 6mm creedmoor on Rem. 700, Shilen barrel, McMillan, Knight force.
