I've never owned a 270 win [ got the wby version in a no. 1 ] but a friend sent his new Sako in 270 win down last year for me to work up a load for .
I gave it back after a month , and told him :
1. It was the most accurate out of the box WITH FACTORY AMMO that I ve ever shot !
2. I could not beat the factory ammo as far as accuracy and could not match the velocity !
Wish I could remember which factory shells it shot so well , but my notes are packed away .
I post this only because I steered clear of the cartridge so many years because of the " hunting accuracy is all you can expect from the 270 win " comments I read .
I still like the wby better . mine puts the 130 tsx into little bitty groups about 300 fps faster than his win .
