bigbulls again thanks for the help. Buddy I'm plum ignorant when it comes to MOA's and other terms but thats allright by me. Around home we, or I should say, I measure my groups in inches. What does a minute of angle convert to in inches? While I'm on the subject about being ignorant to terms, what does a ballistic coeffiecent mean when looking at ballistic tables? As you can see I'm as green as a gourd when it comes to hi po's.
