A few years ago I too used a 308 on my elk hunt, actually took two elk. Cow/calf season in Wyoming. I used a Ruger Scout Rifle 16" barrel. I used Factory Nosler 165gr Accubound. I had a Thunderbeast older Can 30P1.
One Elk at 445 yards the other at 472 yards. I would say 500 is absolutely the maximum range. First elk one shot dropped in its tracks, the second went 20 yards, second shot to finish off.
First time I used Factory ammo, Suppressor, and Non-Magnum rifle. Outcome the same as a 300 Wby, all dead, it's all about a good bullet and Shot placement. I recovered one bullet and it mushroomed just like Nosler shows.
I now use all Nosler Accubonds in my hunting loads I develop. Nosler now offers a LongRange Accubond 168gr, not sure if it's in there Factory ammo, but would still suggest 500 yards as maximum range.
I strongly would suggest that you Chrono your gun and ammo know it's drop. If I recall at 600 yards, the bullet will drop additional 90" from 500 to 600 yards. So your guide is correct 500 maximum for the 308. Good Luck.
