The ammunition for both the .400 H&H and the larger belted .465 H&H is made only by Wolfgang Romey in Germany, the same maker makes a number of Holland's own proprietary rounds bearing Hollands own headstamp along with the tell tale pentagon shape that is Romey's trade mark.

The one exception was the .700 H&H N.E, which although has ammo offered by Hollands does still rely upon a run of ammo made in the late 1980's by Jim Bell. Both Romey and Kynoch load for the .700 but hollands do not sell this round by either of these makers
