Now put a 215 Hybrid in the 300 win or a 230 Hybrid in the RUM , 30-378 or any larger cased 30 and watch the long range spanking begin in all aspects.
I have tested extensively. The best example is a 7mm-300 win, which I have built several, compared to a 300 win. Side by side in the field I clearly have a reason I still shoot the 300 win. Until the 195 Berger get to our hands that's just the way it is.

+1 this is like comparing a .30cal to a .338cal rifle. The .30cal can come close to the .338 but when the .338 is loaded up with a high BC 300gr bullet then it will really outrun the .30s by a lot.
