I've recently freed up enough money to pull the trigger on a custom built rifle and wanted some feedback. Which action do you prefer between Defiance or Bighorn? Should I go with a Proof Research CF barrel or Bartlein/Kreiger steel barrel? And finally, can't decide between 6.5 CM, 6.5 PRC, 308, or 300 wsm. Rifle will be shoot a max of probably 1,000 yds unless I can find somewhere longer and I'd also like to be able to hunt with it. I have a Seekins Havak in 6.5 Creedmoor already so that's complicating my decision a little lol.
