[QUOTE="Halleywood, post: 1008096, member: 74105"] I have no experience with ballistics programs, but I have been playing around with the G7 ballistics program and my STW info. I shot at 100 yards, then at 300 yards to get my drop and back into my velocity. My Dad has the chronograph so I can't read these loads. Well when I put in my zero at 100 and a 9 inch drop at 300 I'm getting 3043 velocity. Great! Well my 100 yard group was 1.5" high at 100 and my 300 yard group was 9" below that. So I was playing with the zero adjustment 1.5" high and -7.5" at 300. From that it gave me 2787 velocity!! My simple mind thinks that the bullet drop is 9" whether I have the zero at 100 or 1.5" high at 100. Why would it give me such a large discrepancy and what am I missing???? I wish I had the chronograph so I could just know my velocity. [/QUOTE]
