Interested to read more about his comments of differences between uphill/downhill.

You need this !

It all depends on what "good enough" needs to be. I always input range and angle separately other wise the calculator doesn't know if it needs a wind value for 550m or 600m. The real world difference in shooting 30deg up vs 30deg down is next to nothing in a distance thats achievable. Ie where do you plan to shoot over 1000m at a 30deg down slope. We shoot some decent angles down here but thats never going to happen.

I disagree Ned, a bullet it's the true distance in a horizontal line that counts it's immaterial if that's angled up hill or downhill. Gravity is a constant.

NED is correct.

"A bullet always shoots slightly higher when it is fired downhill than when it is fired uphill at the same angle. The reason for this is that when the bullet travels upward, there is a component of gravity acting as drag on the bullet that increases the drop slightly.
When the bullet travels downward, on the other hand, there is a component of gravity acting as drag on the bullet that decreases the drop slightly."

I stand correcited however a theoretical 2/10 of an inch difference in drop at 500 yards between going uphill or down hill doesn't make any difference to your point of aim in practical terms.

Good find. All I found on my google search was some stuff on bowhunting and shooting up v downhill. A lot more relevant for them than to us throwing lead around. (i.e. the example I saw was a whole yard of elevation difference over 60 yards between up and downhill. Can't remember the angle)

Its all makes sense to me now, thanks for the insights

Remember these?
And then use your cosine and los.
Can't fuck it up then
