A bullet, no matter the caliber, begins dropping as soon as it exits the muzzle. This is due to gravity. Depending on your scope or sight's zero, you can "cheat" gravity by creating the illusion that your bullet rises to your point of aim. No bullet, no matter how fast, ever rises above the centerline of the bore.
A bullet fired from a .270 can travel about 5 miles. It is accurate to about 900 yards.
Bullet diameter
Just about equal. The parent of the .270 IS the 30-06 (necked down to .270). TYPICALLY (but not always) the .270 fires a slightly lighter bullet at a higher speed.
If it's a 270 load, yes.
A 270 Weathery will shoot any standard 270 bullet. However a Weatehrby Magnum will not. The Weatheby Magnum is like a Winchester Magnum which is a shorter and fatter cartridge.
150 grain vld
The lowest is probably the Sierra HP 1800 at 90 grain.
