DD mk18 questions

Sent off for my stamp , looking to get the mk18 by DD . Question for the people that shoot or have a sbr like this .

  1. What grain ammo do these like ? With a 1&7 twist hoping it will like heavier ammo .

  2. Is it a 100 yard to 200 yard rifle ? I like to stalk hogs and shoot a lot .

  3. Was there anything you had to change to get it to function better ?

Thank you for any help or tips
