I had this conversation with Allen Day once upon a time. He was an unapologetic fan of the 300 Win Mag and used it extensively. He owns 30's and 338's of identical construction. He shot them both a bunch and in our conversation confided that the 338 with 225's was an easier animal to shoot than the 300 with 180's. Performance on game wasn't discussed.
Something else is different about the rifles if you can shove 25% more bullet with the same amount of powder and find less recoil in the lighter round. Yes, the 180gr 338 is going slower, but the difference in bullet weight is big.
I have never enjoyed any 338WM.
I have a large bunch of 30 caliber magnums and have considerable time with them... but I am moving to the 30-06 more and more. My last several bull moose have been with the 06 and TTSX.
