I don't agree with you remmy 25-06, physics don't either. If you compare a 270 shooting a 140 gr projectile to a 7-08 shooting the same 140 gr projectile they are virtually identical. I say aslong as the shooter is comfortable with there rifle and can put a bullet where it needs to go any of them are great rounds for elk and muley. The 260, 270, or 7-08 would be the top picks IMHO for a lady shooter.
