I am also a big fan of the ZKK 602. I have one in .375H&H and one in .458Win.

What they need to become really good is a proper restock and some polishing of the action...particulary the feeding ramp..

The safety works backwards wich is no good, I opted for an M70 safety..

What you have is a big, sturdy Magnum Mauser action with 5 down the magazine..

I have shot a lot of PG with the .375 and 3 elephant with the .458, the latter with confidence..

However, for elephant hunting I would prefer a large calibre double rifle but for culling a 602 in .458Win. would be my choice..
