So. I am starting a new build. I need some help on deciding on what round to do. I have narrowed it down to a 6-47 Lapua or 6.5 Creedmoor or a 6XC. The barrel will be a krieger or Bartien Remington varmint 26"-28". I will at times be hunting deer but mostly hitting rock chucks and steel. What do you guys thing.
