If it were shortened to 2.500" or so,like the lopped H&H spawn(264Win,7mmRem,270Wby,7Wby,etc),it'd be sumptin'. As it sets,the 300 Ultra is very COAL stingy,beings it has no wiggle room to work with as a repeater fed high BC's. Which of course is part of the appeal in the 338Ultra and it's shorter hull.

Folks is to quick to fixate headstamps,which mean far less than boolit selection. Very easy to coax a .625BC kissing lands from within it's box,ala 7mm RemMag on a 700 and it'll always steal the show,with 3100fps from a 24" being a breeze. It's the free-est of lunches,regarding relative "Oooomph",residual speed,wind bucking and bang for the buck,on top of minimal felt recoil.

The big picture escapes most,if not all.(grin)
