The Oberndorf Turkish Mausers built between 1903 and 1905 were converted from 7.65x53mm to 7.92×57mm in 1930s.
To do this the magazine was lengthened, the feed ramp was shortened, the large ring was notched, and they were rebarreled.
While I can lengthen a VZ24 from 7.92x57 or 7x57 to 3.34" cartridges like 6.5-06 or 300 WinMag, but I cannot lengthen a 1903 Turk to 3.34", as it has already been stretched.
So cartridges like 257 Roberts are a go, and 30-06 no go.
257 Roberts Overall length 2.780 in (70.5 mm)
308 Win ......Overall length 2.810 in (71.12 mm)
7.65x53mm Overall length 76.00 mm (2.992 in)
7.92x57mm Overall length 82.00 mm (3.228 in)

With different bottom metal, the VZ24 could get still longer.
With cut and braze the bottom metal, the VZ24 could get still longer.
But will just me milling out more space in the VZ24 bottom metal, it is paper thin on the end with 300 Win mag.
