Theek -
I load 168g TTSX for three of my .30-06 rifles, Daughter #1 is using 130g TTSX in her .308 Win. The fourth .30-06 gets 150g AB. Shot a cow with that combo in 2010 and it was on the ground before I recovered from the recoil.
Take what you shoot well.
Never had a fail with 165 TSX or 168 TTSX on mule deer or elk from .30-06 or .300 Wby. Never shot a whitetail with one. I’m inclined to not consider anything lighter than 140 gr in 7mm or 150 in .30s, but that’s just me.
