Now there's a gun/caliber with some interesting history! Developed in 1909, right on the heels of Jeffery's 404 (1905), the 425 Westley Richards was the first recessed rim cartridge (i.e. rim smaller diameter than case). It allowed Westley Richards to build a rifle on a standard Mauser action using a larger caliber than .423 of 404 Jeffery while retaining the standard bolt. 404 Jeffery rimless cartridge required opening up standard bolt face to the outer limit of what the metal could hold. The recessed rim concept, while it looked good on paper, did have some feeding issues that were challenging to overcome. Eventually, Westley Richards went with a vertically stacked magazine extending below (probably well below?) the standard Mauser floorplate. If yours is of standard staggered box construction, it sounds like you have an early production collector. According to Wikipedia, the standard Mauser action 425 WR with stripper clip port was preferred by game managers for faster reloading. Large scale culling with a 425 must have been brutal ... for the culler!No it doesn’t. Nothing has been milled out for a stripper clip unlike in the 425 WR.
