Just out of curiosity, I noticed a huge difference in Dens Altitude today from last time I shot.
Here's the conditions:
<span style="text-decoration: underline">25 Sept 2009 </span>---------------<span style="text-decoration: underline">16 Oct 2009</span>
Temp: 86.2-----------------------Temp: 65.8
Humidity: 68%---------------------Humidity: 71.7%
Dew Point: 76.1------------------- Dew Point: 56.4
Baro: 30.02----------------------- Baro: 29.91
Elevation: 10ft---------------------Elevation: 10ft
<span style="font-weight: bold">Dens Alt: 2092</span>---------------<span style="font-weight: bold">Dens Alt: 653</span>
Sunny / clear----------------------Partial clouds / cold front
Is this drastic drop in D/A normal, or did I get my measurements flucked up?
Second question, how would this drop affect my shooting at distance? I keep hearing about the importance of density altitude, but haven't been told what role it exactly play on the bullet in flight.
