Re: CZ-527 and a hello.
H-S Precision has a few good stocks for the CZ-527.
I have a 527 and in factory configuaration, it shoots quite well. The test target that came with the rifle showed a 3-shot group that went 0.374 inches, shot at 100 meters. I like that.
Last time I shot for group from my field rest (cross-sticks at 100 meters), it shot a 3-shot group into 0.875 inches (seated with stick in field conditions--laser ranged).
Oh, yes, this is in caliber .221 Fireball.
