The environmental factor is HUGE.
This is shot ( 55 M / 13 gr Zan slugs) in the daytime, with not horrible bad wind force, but not at all minding them / trying to read them.
Also at any given time +4 different wind directions indicated by flags, some times apparently a strong gust coming strait up out of the earth CUZ some times a flag would point strait up.

The remaining 4 dots on the same target shot 5 hours or so later when wind died down some, not completely gone though but A LOT less aggressive, and more of the wind indicators in the field pointing the same way.
Again here not minding wind or trying to read it, just shot from the zero,and then putting enough shots on each target to rule out the luck factor.

As usual shooting my Epic airguns Two.
same weather today, and you can generally hold your shots on the black dots, but you damn well better pay attention to the wind.
If not, well your shot would easy be pushed 50 - 70 mm off course.
