It's somewhat a topic of debate as the physical dimensions of the 'standard' 110 action and the Lapua 110 action are virtually the same (diameter, length, bolt interchangeability, etc.). However, the receiver was heat treated differently for the .338 Lapua to be able to handle the higher pressures that come with that size cartridge. Furthermore, standard 110 actions are actually small shank, except for the BA models (even the .300 win mag) in order to keep tooling costs down when producing the 110 BAs. So large shank actions were only available in WSM, BA, and/or .338 Lapua factory Savage rifles.
