There's no need to shoot an ELD-X, or Berger VLD Hunting, or Nosler Accubond, or any other super-bullet with super high BC for 0-300yrd deer hunting. Any cup & core bullet will be fine.

Kinda put the cart before the horse to buy the 6.5 Creed rifle before identifying appropriate bullets for your application though. What drove you to buy it?

The ELD's are pretty cheap, so you're not paying high prices for high BC like some other bullets. For shorter ranges, the ELD most likely will suffer from the same issue as any tipped bullet - don't hit anything too hard and you'll be fine, but hitting the shoulder may get messy.

Any expanding bullet which groups well for you will kill deer at 300yrds from the 6.5 Creed.
