Too many variables. Have never owned or shot a pgw coyote but it would likely be between that a Chou bros custom. Scope, s&b or nf. Cartridge, if I was doing only fair weather shooting, I'd likely try lapua 308 Palma brass. As far as bullets and powder go, whatever the gun likes! Chou's can spec a reamer for whatever you like.
I am a lucky guy. Have a custom from the Chou Brothers and just got a TRG in the mail. I can tell you that there are pros and cons to each.
