I’ll throw an alternate opinion in the hat. I think we tend to overthink bullets a lot. And you are probably just fine or maybe even better off using the same ammo you use on deer.
Bonded bullets are generally good in the speed demon cartridges and 308 isn’t that. If you are one of those people who tries to push bullets lengthwise through a critter to the vitals, the bonded bullets may be a benefit. But it will come at the cost of otherwise smaller wound channels and longer post-shot trails. Standard cup and core bullets put in the boiler room will kill any elk or moose that walks.
ELDX bullets are a modern cup and core with higher BCs. If you are only shooting out to 250 or so, there’s no reason to spend the extra money on them because the BCs won’t substantially change your trajectory. If I were you, I would consider using the cheaper stuff and shooting more of it before the hunt.
YMMV, and everyone has opinions on this stuff.
