The round I really wanted to see "make it" was the .376 Styer. It easily makes 1920's .375H&H ballistics and that's when and with what the .375H&H gained it's popularity as a 'GREAT" medium bore. One doesn't need 2,800fps with 270's, or 2,600fps with 300's. Apparently the game got tougher after the Second World war. 2,400fps with 300's used to be good, as did 2,600fps with 270's. BTW- you 9.3x62 shooters, this is exactly what your rifles will do with the same bullet weights and within pressures easily managed in any heat.
: Whether the .30 or .338 versions of the Ruger ctg. makes it or not remains to be seen. Still, it takes a bunch of different rifle makers to chamber them for them to become popular.
: If Ruger is the only one chambering manufcturer, they will definitely fail.
