Found a box of Aquila the other day, black box rifle match. Took it out this morning and gave it a try through my CZ. Worst groups the gun has ever shot. 5, 5 shot groups at 50 yards all over an inch. No chrony but seemed very inconsistent, all over the target. After shooting those 25, I needed to make sure it was the ammo and not me or the gun. I loaded up 5 rounds of 711B and all 5 at 50 yards were all touching, less than .5" group.
