Pacecars, The ZG47 is a large ring Mauser. The small ring BRNOs, the 21H and the 22F were very well made with great handling characteristics. The .300H&H works well with 180 gr bullets and they are better suited than anything heavier due to magazine length. Nosler partitions are the only ones I used in my first .300H&H and they do the job on deer, bear or moose. They also shot accurately in my rifle.
