Teeder,
Oh, yes!
But I must mention a slight technical correction to your post. The B-29 was my fictional wildcat, and the "article" stirred up more reader comment than any previous HANDLOADER article, to the point where I was commanded NEVER to write a similar article.
The 9.3 B-S, on the other hand, is a very real wildcat, the .350 Remington Magnum necked up to .366. I came up with the idea, and Charlie Sisk built the rifles. Actually, he still builds 9.3 Barsness-Sisk rifles for anybody who wants one. Last time I asked he'd built a few dozen, aside from his and the one he built for me.
But some people wouldn't believe the 9.3 was a real cartridge for a while, evidently because of the B-29.
