I don't know I have handled/shot a couple of rifles chambered in 425 Westley Richards. One was a original Griffen & Howe Springfield, and the other was a modern made conversion on a Belgian Mauser. They both shot well enough, and feed with no issues. The Griffen & Howe was particularly nice, very quick handling, and the bolt was smooth like hot butter. Ballistically it offers nothing revolutionary, but that doesn't mean its not capable.
I guess thats what makes rifle goons great, eveyone like something different.
