im going to sound like a know it all
[email protected] this is how it should go.....sight your gun in and practice AT the ranges youll be hunting.....no computers going to tell you how your bullets going to act....can come close....but if its off an inch at 100 thats a big miss at 500.........and you didnt practice with your equiptment at 500....but you think you can take an animals life at that range???????do yourself a favor and find a range that goes out to where you need to practice....practice practice practice...why spend the money and everything on the hunt....then the moment of truth comes and your "data" was wrong and you missed by 6 inches.......? really.....do yourself and the game a favor and practice at the ranges youll be hunting......
