roval,
Rerun with the official elevation in Albuquerque, 5312 feet, the software says:
50 yards 10.74 MOA
100 yards 17.84 MOA
150 yards 26.56 MOA
200 yards 36.17 MOA
These new calculations retain the 6mmbr.com barometric pressure of 29.92 inches Hg. As I recall, meteorologists correct pressures to sea level and the change in elevation in the ballistics calculation should reflect the actual air density at elevation.
Again, just jumping off points for individualized testing. For the record, though, when I compared my .30-06's performance against the ballistics software predictions out to 300 yards, I was satisfied that I would have to expend a great many rounds to tease out a mismatch. Certainly no deer or elk would ever know the difference, which was the extent of my interest.
