So I went to my secound ever 3d shoot yesterday. I did pretty well, but would like to get better. I shot 11 down.... 289 5x's. (the first shoot I shot a 178 with 1x). So what I'm wondering, is how everyone judges yardage. So do y'all have any tricks or secrets, or do I need to learn the different targets or what....???? Any help would be greatful! THANKS!!!!
