There is so little difference between a 280 and a 270 that you are splitting hairs.
Most 270`s are extremely accurate, mine is a G series model 70 FWT from 1984, I also had a Remington 700 in 280 and it did not shoot as well as the 270.
The Winchester is like shooting a shotgun, point and shoot.
The gun just flows up to your cheek. It is still very accurate and has taken several Sitka Black Tails in Juneau, AK and alot of Whitetails in NW Montana, Noxon area.
The 280 does have a large following though, my Remington could of been just a poor barrel, its gone.
Shoot strait and keep your powder dry
Enjoy a little of every day
