Re: Need a Little Help With a CZ 550 FS
Absolutely cold barrel between groups. For the first and second groups, the first 2 shots of each group were .053" and .185" respectively and best of all, if you superimposed the aiming point for each, the 4 shots would have been one hole. I can live with that, after all it is a hunting rifle that will very likely never be used on game for more than 2 shots.
Now the bad news - the third 3 shot group looked very much like the first two, but it had shifted. The first two shots measured .190" center to center, but they were .9" high and 1.1" right of the first two groups. That was disconcerting.
I can already tell that this thing is going to make me nuts. If I limit it to 200 yards and under on dry days, it should be a killer.
