I have only seen the Predator Pursuit in 16" or the 20" that I own, I ran a couple factory loads before I had my handloads ready, and the Rock shot it all. Winchester white box shot good. I was and still am very impressed at how tight the Rock Rivers shoot. I added a Rock R-3 18", and my son has a 20" Coyote, they all shoot sub MOA with our handloads. Enjoy your PP.
