I'm wanting to build a PRS style rifle for some local tactical shoots. Budget is 1500 for the gun. What would you do?

Barrel - cal, contour and twist
Stock or Chassis - which?
Action/trigger - sa vs la, accutrigger?

I'm torn on which way to go and need some suggestions. I currently reload for 223 and 308 and have built a couple of great shooting savages.

Thanks in advance!
