anybody use?

I don't create a new chart for everyday, but infact have combined several sequences to form one chart for where I typically hunt. (different wind speeds for drift for example)

My chart is based on 1200ft above sea level for example. That, and 35 deg. with std barometric pressure at that elev. and temp. That's not exactly what I see everyday where and when we hunt, but it's close enough, determined through experience. In the summer when temp climbs, my chart is off ( I always shoot high). I could develop a new one for the temp, but I just shoot the first shot over and adjust from there.

If I was going out west and hunting at say roughly 8500 ft. I would definately want to do a new chart for that elevation. As Boyd said: most of this won't affect you that much under 700yds but any one of these things can put you over or under a deer at 1000. Believe it or not, there is an Exbal program to load on your PDF and develop an "exact" drop for the current conditions. Granted you have the ability to determine them. People are making 1st shot kills to extreme ranges using it. Kestrel makes great instruments for determining wind speed, temp, pressure, etc.
