It depends on what you consider light for caliber, a bit on what and how you hunt.
Keep any of them at 1800 fps at the target, and things should work out.
I was thinking 110 in the 260Rem, 150 in the 308 and then 165 on 300 WM.
Mainly hunting deer, but black bear, sheep or goat and atleast 1 elk hunt are all on the list this year.
