geez, 338 lapua necked down to 7mm? the lapua is already a .416 rigby necked down to .338, so now theres a .416 necked down to .284? wowsers.

No the 338 Lapua isnt simply a necked down version of the 416 Rigby. While based on the Rigby case, the Lapuacase is shortened and the web area is thickened to be able to take greater pressures.

Here is a picture for comparison.

Left to Right.. 338 Lapua, 416 Rigby, 30-378 WBY IMP, 378 WBY
