[QUOTE="Fiftydriver, post: 884058, member: 10"] The 338 Kahn is simply a 338-378 Wby with a conventional 35 degree shoulder angle. This does not really increase case capacity at all, just a different shoulder design. When loaded to pressures that result in good case life with the Wby or Norma brass, you will top out at around 3050-3100 fps max in a 30" barrel length. The 338 Raptor is still in its infant stages but it is a clear step above the Kahn. It will easily get into the 3150-3200 fps range with 30" barrel length. Again, these velocity levels I am referring to are loaded to very responsible chamber pressures. I can get 10 firings per case out of my 338 Raptor loaded with the 300 gr berger at 3140 fps. I would call that very comfortable loads. [/QUOTE]
