Not sure what you are getting at here or the point your at attempting to make. (???) Hand loaders/ reloaders do not look at SAAMI/CIP when they create their own ammunition.  While I do not speak German, I can read and comprehend articles. Note I have in the past used German articles as references... if that is what you mean. I am still working on the article and remains incomplete. However, one does not look at an individual's reloaded data and give it credence from a Wikipedia standpoint. Factory manufactured ammunition should only be listed for illustrative purposes and for good reason, they respect a standard which is safe in a vast majority of caliber specific firearms. Conversely, if no standard is maintained for a given cartridge then data from reloading manuals should suffice. I am well aware that .325 WSM components are available in Europe, a cursory check on component sellers websites evidence this. BGO... However, I am certain that those reloading are not dragging pressure measuring instrumentation and pressure testing their ammunition against SAAMI or CIP standards.  Not sure what is being alluded to in the S&B; "looks like... FMJ" but they do not manufacture 325 WSM ammo. 
 It is certain that the 325 WSM will become another also ran cartridge.  Certainly, rifle trends show that much. This was an 8mm cartridge designed from the US and Canadian markets and was a commercial flop from the beginning. But what does that have to do with anything in the end, really.  It is still a cartridge and should be treated in an objective manner on the Wiki - just like any other article. Yes the 8mm IS is established in Europe, and the 8mm RWS much less so but is hanging on, the 8 Rem Mag is dead and almost buried and .325 has both feet firmly planted in the the grave. So what...
