Is there more detailed information on the new standard calibres .300, .338 and .375 Norma Mag?

When producing the current catalogue, we mentioned these three cartridges briefly as being planned but they were still undergoing development. We assumed that the .338 and .300 would be suitable both as long distance and hunting cartridges. Both are now available as cases. The .375 is still at the development stage.
