Home Forums Hunting & Shooting Hunting Optics How to use that new SWFA scope- reticle, turrets and proper usage.

as dennisinaz said, it's a way to simplify things; instead of using 3-4 different weather value inputs, you can use just one. FWIW temp plays a big part in this calculation even if the elevation doesn't change; for example in my area near sea level, we're at -1,500 to -2,000 ft density altitude right now (clear and cold weather), but it will change to 2,000+ ft d/a when it warms up a bit and gets cloudy, even without climbing the mountains.

Taking that a step further, you can print a dope chart for every 2,000 ft change in density altitude in your area and have your bases covered pretty well all year round.
