The Federal JSP in the blue box is a little better out of my CZ than even the Lapua, but I didn't find any of the other Federal ammo to be worth a shit. The Lapua runs around 1.25moa, and the blue box will do just a hair better than that. Winchester JSP from the silver box is the 3rd best and usually does about 1.5moa, while Hornady Zombie Max is a very consistent 2moa. IIRC the Czech made S&B was 5th best at around 2.2, and everything else turns into a shit show from there on out for me.
