Where are you getting a 300-500fps delta? That makes no sense.
Even if you compare 200gr loads for each, they would be withing 100fps of each other. And with a 338win mag, which I do have experience with, I can get 3100fps with a 180gr bullet. Totally different animal than a 338-06. You can achieve 18gr more water wieght I believe with a 338winmag.
He must be comparing a 200gr to a 250gr. Fired out of either a 338-06 or 35 Whelen I would expect something in the 2400-2500fps range with a 250 but I have never tried anything that heavy.
