In my tight bored 303 Brit (.310" groove to groove) and both my 300 Savage rifles I actually prefer some cup and core bullets to Barnes. Because my 2400 to 2500 FPS rifles still give expansion to the ranges I can use those rifles with their iron sights. And let no one tell you different, a 303 or 300 Savage with a 180 grain bullet kills elk just fine out past 200 yards. They kill deer and antelope fine out to about 300. Maybe farther, but the longest kills I have made with mine were just a bit over 300 and the bullets exited and left big holes.
So the issue can become complex.
In my Long Branch and my father's only #4Mk1 I run heavier ( 180,215) cup and core bullets at "regular " 303 velocities, but in my Ruger single shot I can run the Barnes 150 TSX's at 308 type speeds, and get really super accuracy and expansion/pass through's at well over 300 yards on deer.
The longest one was a hair over 370 yards with a heart shot, deer didn't go 20 with soup for lungs!
