Greetings @ chainsaw,
No criticism just my clumsy phrasing. The 7x64 is loaded to a higher pressure than the .280 Rem and the faster twist allows heavier projectiles. I see that the .270 is now being given a faster 1 in 8" twist by some manufacturers which, once decent high BC projectiles become more available, will enhance its long range performance. Nothing stays the same forever it seems.
Regards Grandpamac.
