Don't do PRC. Too much recoil, too little barrel life, too much fouling for a 200+ round match, not enough magazine capacity.
6.5 creed, 6 creed, 6 GT, 6 Dasher if you reload.
You want, for the PRS game anyway, a 16-25lb rifle with an efficient brake, and minimal recoil. 10-12 round magazines. Stock with ARCA rail built in or able to be added.
First and foremost, I would observe, participate in, and/or R.O. a few matches first. Check out the gear and watch very closely to what works and what doesn't.
