As I mentioned you do need to check out Zastavas before you buy them. The QC is a little hit and miss.

The CZ 550 is very rare in this country but I managed to find a used one. There is a lot to like about the CZ but it is way too heavy for a 375 IMO. It is a true magnum Mauser size. Mine has become a 458.

My favourite 375 H&H rifle is a Mauser model 2000. It’s a PF but I’ve had this rifle for 40 years and it’s never failed. They are a lightweight rifle designed to be carried. These and the Mauser model 3000 were based on the Heym SR20N action with styling for the American market. They are a real sleeper and not that expensive compared to other options, if you can find one.
