You are absolutely correct. The wild cat was/is called a 338/300WSM
It is not simply a necked up 300 but it is based on the 300 WSM, and just like most company's
Ruger changed the case dimensions so they could call it theirs just like Nosler did with the 280 AI.
The 200 grain 325 and the 338 both have identical velocities (2950) and energy's (3864)
The largest bullet for the 325 is a 220 grain spitzer and the 338 rcm has a very good bullet
selection in 225 grain +
The 338 RCM is no better than the 325 IMO except for the bullet selection and if loaded with the
250 grain bullets in 338 it becomes bear medicine in a short action.
