Ballistic Coefficient (G-7 if possible).
Muzzle Velocity.
Bullet Weight.
Altitude if you are above about 3000 feet.
Sight height above center of bore.
Plug into a simple ballistics calculator and you should come up with solutions that are quite good to the subsonic range of the load.
However, a few things you forgot that must be quantified in order to understand hit probabilities.
1. Mean radius of the ammunition so you can extrapolate Mean Radius at a distance.
2. Hit and Kill zones of target.
3. Probability that the shooter is able to hold well enough, estimate wind well enough, and pull trigger well enough for his shot to maximize the probability of hit / kill of his ammunition against a specific target at a specific range given specific environmental conditions. For this you will have to deal mostly with physical and psychological stress on the shooter.
Most of your variables, if they have significance, pale when considering the capability of a shooter to make a shot.

The list was everything I had been asked for after sampling a few different ballistic calculators online and from the Google play store. I think there were a few things I left off.
As far as the abilities of the shooter go, that will come later. Starting with the ideal settings, then will slowly work in probability of user error.
