[QUOTE="SBruce, post: 565160, member: 21068"] That would be nice. I'd like to hear if anyone's come across this also. The programs I've played with (NF/Exbal, Sierra and a few different online programs) only allow us to input a poi at a couple of distances and then they will correct the velocity or sight in distance to compensate. They also have ways to change the BC to suit, but it seems to take quite a large change in BC to make much difference.......are published BC's really off by that much.? I kinda have the belief that atmoshere, wind changes, light and mirage seem to have quite an impact beyond 1/2 mile. Heck, some cartridges with low BC's are extremely affected once beyond 400 yds. I've got two different altimeters (or pressure monitors, whatever you want to call them) that both give different readings on the same day from the same spot, different by .05 in hg. Which one is correct??........hard to say. Also, I've got two different ballistic programs that each use a different "standard pressure" at my altitude, and one has to be .5 in hg less than the other to give the same dopes beyond 1/2 mile.....which one of them is correct??........again, hard to say. Interesting subject, tons of variables. [/QUOTE]
