[QUOTE="Broz, post: 397629, member: 7503"] More data....:rolleyes: After shooting the group at 1182 yards this morning and it being high. I simply raised my MV to 2780. Again I feel this is close due to tha fact the 300 smk chronoed at 2850 and matched exbal dial ups at 2805. Remember the chrono I have proven to be fast by 30 to 40 fps. So I feel the 1 gr reduced charge with the bergers that chronos at 2820 should be in the 2780 area. All that said, and new sight in data of 2780 MV, DC .495, G7 BC .419. I just went out to shoot before dark. Entered field conditions and engauged the 1395 target for a cold bore shot. With Coriolis entered and on, no spin drift or windage adjustment was made, LB called for 36.1moa up. I dialed 36.0 and shot once. Pic below. I then engauged a target at 995 yards. I shot 3 into a 4" group that was about 6" high. LB called for 20.4 and I used 20.5 So, I feel, the program is a bit high with mv of 2780. It seems I need to raise the mv a bit more, will keep adjusting. Coments??? Jeff [IMG]http://i246.photobucket.com/albums/gg91/JBroz1/DSC02348Small.jpg[/IMG] [/QUOTE]
