ColorNotColour....Pull up the JBM Ballistic Calculator on the web and feed in the appropriate information for the round you are shooting and specify the minimum/maximum ranges and the increments with which you are interested...When you hit calculate it will give you a pretty general idea of your trajectory....i/e, bullet drop
Then take that information to the range and set up a few targets at various ranges and without changing your optic settings, shoot at the various targets, always aiming at the bulls eye...You will find out a lot of information about your cartridge, optic, and it's really good experience for learning about what capabilities you have present...
