The CZ Magnum actions are great for boomers, but IMO, too big for a 375HH. I Just don't need that much heft in a 375. If I were to get another, it'd be chambered in the Rigby case.
I'd go 375 Ruger. Maybe a Howa barreled action and get a McMillan stock. If you can stomach Weatherby styling, you could probably find a decent take off stock with some nice wood to go along with.
Lots of Supergrade 30-06's around as well, pick one up and send it out for a rebore in 9.3. Have a flat milled on the old mark and a new one rolled on so it still looks nice.
You could likely find a nicely stocked one and be into a nicely finished medium bore for not a lot of money.
