OCW: Do you like 3, 4, or 5 shot groups?

I've found that a chart like this is helpful with regards to this.

What is the scale of this, seem to be way out of proportion, maybe there is a trend but very subtle.

If the terrain was perfectly flat then there would be a minimal impact. If there is a berm or other elevation change there is vertical.

Further, if you have a headwind or tailwind and you pick minimum vertical over minimum horizontal, you are not likely picking the best group.

So when I have to pick a load for competition, I pick the group shape based on the current wind conditions. That doesn't always mean the least vertical wins.....

Yes terrain can cause vertical wind and is difficult to call. Straight head or tail winds are small impact a 10mph is the same as a 14.7 ft/s velocity change.

Frankly, I have no idea as to the scale of it, though I've found it to be a good representation of what I've experienced shooting in windy conditions, even at 100 yds. And I'd say that the "scale" seems to depend on the strength of the wind as well as the mass of the projectile (note: mass is not the same as weight).

The only factor in wind drift is bc. The mass does not enter.

If two shots suck then why shoot a third?

To connect the dots.
