[QUOTE="groper, post: 475030, member: 12550"] Assuming you have all the variables correct besides the BC, its only 3 clicks difference @ 800yds on your scope assuming a 3200fps velocity.... If your at 5000ft above sea level, its only 2 clicks difference. If you then use 3250fps to the velocity and .74 BC, your less than 1/4MOA click difference from the 0.9 BC and 3200fps. This is without any other errors creeping in... See how fast things can go wrong? Are you saying that youve shot your 7mm AM to 1 mile, and used a 0.9 BC, and your trajectory was too high??? If so, then you have HUGE problems with your calculations and your trajectory fit... If not, can you explain it better? [/QUOTE]
