The smart play is to use this tech to bring higher performance to older calibers. There would be a LOT of interest in the ability to use a hotter .308, .30-06 etc, even if it needed special marking so people don’t stuff it in older guns. Basically make +P variants of common use calibers and you have both mass adoption and it really shows what the tech can do
I know it can be done, a few of us crazy bastards on here have already done it with resized Sig hybrid cases, the limits are really the metallurgy on old bolts and chambers, so just like 9mm +P, .45 Super, and high pressure 45-70, put a warning label on it and be done with it.
