If it wasent for some of you guys like Broz , Shawn and others I would throw my NF ballistics software in the garbage but I have seen photos and video of you makeing extremely long shots so I know it is me but I dont have a clue as to what to do. .... As you can tell im a little frustrated. I need help . I cannot get my program to give me the correct elevation dope . Example : The last time I shot was at 556 yards ( not that far) so I thought I would atleast be within the 8" circle that I was shooting at . I shot a 3 shot group it measured 5" from center to center , I then measured from the center of the group to the center of the bulls eye and it measured 8" high. I can handle being left or right because that could be my wind reading skills but my confidence is lacking on the elevation dope that my program is giving me . A question or two and then I will give you all of the details concerning what I had entered into my program the day that I shot. 1. How close can you get to center of the target with your program at this distance ? What should I exspect or what is the norm ? 2. Just throwing this one out there , I have never calibrated my Kestrel 2500 NV . Is it possible that its not giving me precise info to input ? Now the details of my load and the conditions for the day of the shoot. 210 Berger Rem Brass Fed 215M primer 85.5 Grains of Retumbo 300 RUM Elevation 693 Temp79.0 R.H 62.0 Baro 29.18 Yardage 556 MV 2900 NF called for 8.50 MOA up. Note with my program it has a box with a check in it, to calculate the standard pressure and I clear it out . Im pretty sure this the correct way. Almost forgot that this is a new pound of powder with different lot number. Let me know your thoughts I will greatly appreciate any help . I dont have a cosine indicator yet and I was on the top of a ridge shooting down hill. Would this have made me hit high ?
