oldtommo68, 
the ChairGun chart AirgunBill posted above has the following columns (left to right):
At "Angle" (e.g., 5⁰),
the pellet will reach as far as the maximum "Range (x)" (337.3y),
and reach a maximum trajectory "Height

" (36ft),
that trajectory height will be reached at the "Range" (210y),
and it will take "Time" (2.9083s) to get to the maximum range.
Correct me if I got this wrong!
Yeah, a little confusing, the terms, but ChairGun is a very helpful program. ➔ I'd be willing to pay good money (up to $30) if someone took this program under their programming wings and sold the updated and improved versions....
Any takers...? Over at GTA a lot of people also seem to be using it, several British airgun forums
have more than twice the amount of members than the larger US forums, so plenty of users who'd chip in, I'd hope.

I did some calculations about
how far different pellets and slugs can reach out — and still do damage. Those are two different issues, it seems.
Here's what I found:
PART 1: How Much Remaining Energy Is Dangerous? Research-based data on how much energy is necessary to do damage to the skin and to the eye.
AND:
PART 2: Max. Range and Remaining Energy at Impact Comparing the max. range of various .22cal projectiles:
▪low-BC Wadcutter (RWS)
▪mediocre-BC hollow point pellet (Hades)
▪high-BC domed pellet (JSB 16)
▪high-BC, very heavy domed pellet (Monster)
▪extra high-BC slug (22gr)
