I had an 8mm Gibbs built for Dad about 20 years ago, using his first ever deer rifle(98 Mauser) for a donor(needed a new barrel anyway). It's been a lot of fun, it's that rifle that got me started reloading.
That being said, I don't load it much past full house Euro 8x57 anymore. Some of the "published" loads for Gibbs rounds are blasted HOT!!!. The 30 Gibbs comfortably fills the gap between the 300 Win Mag and the 30/06. If you enjoy it for what it is, a neat retro oddity(probably a design ahead of it's time), go for it.
