Just follow the instructions and it will calculate and display all you need.

It is designed for the SR6, SR12 and MAP reticules but I find it is is usefull for calculating aimpoints for just about anything.
this will depend on your velosity(foot lbs) over here were the limit is 12ftlb, would i be wright saying you have no such restrition on airguns over in the states
