Keith, if you read the 'articles', I believe you will see that we provided due recognition to Mr. Barnes, and others, who employed 'short' thirty caliber cases before us: in shooting, especially wild-catting, there is [almost] no such thing as completely new, and, regarding viability, application plays a decided role.
While the .308x1.5 Barnes was/is essentially, a 30BR, the Barnes paradigm, up to and including contemporary cast bullet cartridges, is not quite up to contemporary bench-rest standards. The concept, was completely different.
Using jacketed, lead-core bullets, at 3000 FPS muzzle velocities, WE 'discovered' and applied the adaptations necessary to render the 30BR competitive in bench-rest tournaments. And while thinking of names, don't forget
Jim Stekl, who 'invented' the BR case design - not exactly a .308x1.5". Interestingly, following Remington's adoption/introduction of Mr. Stekl's cases (.22, 6mm, &7mm BR), a
LONG interval elapsed before someone (
Ronnie Long) recognize the [bench-rest] potential of the thirty caliber version!
For a good laugh, check out the Sierra loading manual, where their gurus relegate the 30BR to the status of a cartridge in search of a use - I'd recon that, long ago, they'd pigeon-holed .305x1.5 at the bottom of the same file!
