the bolt faces of the 30-30 and .35 are quite different. The 30-30 bolt face is much wider to accomodate the rimmed cartridge case. The .35 Rem uses a regular .473 bolt face, although the cartridge casehead itself is around .460.
It might be possible to adapt the bolt out of a .307 or .356 BB 94 if you had a spare one laying around.
