Excellent advice so far from very experienced airgunners but if you need more detail like a new airgunners might:
Chairgun is a airgun ballistics calculator available for smartphones, ipad type devices. They also have a computer version. All require more exact scope height than what you stated and there are ways to measure that.
I personally use a paid program that you may be familiar with because it is also used by powder burners. Strelok Pro.
Check them all out and you will find the answers to your questions. Truly a fascinating sport we have here.
