The .325 WSM is basically a 8mm short magnum.I'm hesitant to jumpat any new cartridge because most become dinosaurs in 5 years or less ,more so with Metric calibers.I'm sure there's nothing wrong with it but you won't be able to walk into a backwoods store and pick up another box of ammo or brass if you reload.Look at what happened to the Rem 5mm rimfire! Better balistically than both the .22 Mag and the 17HMR that is all the rage now.Reminton was foolish enough to destroy allthe tooling for the 5MM as well! Now the .204 [a 20 cal or 5mm as you wish]is hot for varmints.Reinventing the wheel again...............Harold
