Nobody makes a 180 in .277". Be far too long. Heaviest Barnes .277" is a 150.
Barnes does not market a 180gr .277" bullet.
Even if someone was selling 180gr .277" bullets, the odds are that most factory 270win rifles would not stabilize them. That is one reason for not offering such a bullet, the other being that it really offers no advantage over the .277" bullets that are sold now.
This bullet just stabilises with a standard 10” twist. Some rifles shoot quite accurately with this bullet. Rifles with a barrel twist faster than 1 in 10” are fine.
