There's simply no way to get as much sectional density in a factory .270 Win, and essentially no hunting bullets intended for fast twist .277s.
I remember WHEN sectional density was important OR more important than today >>> because of newer Controlled Expansion bullets. S D is a no. indicating the 'supposed' penetrating ability of bullets....
BUT with Controlled Expansion bullets, S D does NOT mean as much as it used to.
There are several examples of 'Light for Caliber' Controlled Expansion bullets pushed at HI velocities. They work too.

SD was isn’t nearly as important as many think. I’ve seen 458 mag 400 grain flat point mono metal solids out penetrate 500 grain lead core solids. Construction and nose shape are more important for penetration.
I got banned on another web site for a debate that happened on this site. That's a first
