Acquired my first .308 at age 15, over 50 years ago. Tried to buy a box of 180-grain factory ammo, because that's what "gun writers" advised for elk. The guy at the counter of the Beaver Pond said he'd found 150's more effective on elk, so I followed his advice.
Found he was right--and in general have used 150s (or 165-168s) in the .308 ever since. They work fine--along with 130 monolithics. My wife killed her last elk, the biggest cow either of us have ever taken, at around 200-250 yards with a 130 TTSX--which broke the left shoulder and ended up under the hide at the rear of the right ribs. The cow staggered maybe 20 yards, essentially falling all the way.
