I had pretty good results from Prvi 155gr match. IIRC sgammo has them for like $13/box. They were around 1.5moa in my bergara. Excellent price/accuracy ratio.
So far that rifle prefers 175gr SMK loads, with FGMM being the best. They shoot less than a minute for less than 5 shots, and between me not being the best shooter to start, eyes getting tired, and heat, open up to about 1.1 by the 10th shot. I believe a better shooter could use that rifle/ammo and hold it around .75..
I think if I was going to do a PRS at my skill level, the prvi will do the trick.
My barrel didn't care for the hornady loads. They were all at least 1.25, pushing 1.5, and the same price as FGMM, if not more.
The fiocchi SMK loads shot as good as the other brands using the same bullet (both 168 and 175). Ditto for IMI razorcore.
I tested a box of fiocchi 165gr SGK, and they did about 1.5. Bought a few more boxes to keep on hand since they're actual "killing stuff" bullets.
I wish i had my logbook handy, but I'm out of town right now.
