I know a few guys who use the lighter bullets in the 280 AI One of my friends like the Nosler 150 grain B/T two others like 150 and 140 grain Partitions. They think they get better results putting animals on the ground faster..
Then again, I have some other friends and cousins who are 7-08 fans. They hunt with 120 grain Nosler B/T.
Prolly the same thought process. Moving bullets a bit faster.
As long as it works we're all happy.

Take care
