altitude

A lot of us Galaxy S3 and S4 owners are carrying around a device that has far more capability than we realize or fully utilize. Here's a quick and simple method to get both elevation and barometric pressure data in real time from your phone. This may work on other Samsung cell phones as well...

Bullets are hitting the bullseye at 200 yards at altitude of 5,500 feet. Scope elevation knob is set to zero. If I do not change the scope elevation knob; then, bullets will hit some unknown distance below the bullseye at 200 yards at altitude of 3,000 feet. How many MOA do I need to turn...

kinda fuzzy question but i was wondering if the altitude,humidity,bar pressure etc at wich you ammo is loaded effects how it shoots? for example if i were to reload a 308 case at sea level 100 percent humidity and 100 degrees farenheit and then reload another at 9000 feet very little humidity...

Does there exist any literature on the effects of high altitude shooting that I could get a hold of? Originally from Ohio, I have since moved to Colorado and live at 9,000' above sea-level. I am curious about the effects of altitude on bullet flight (ballistics) due to decreased air...

Has anyone done an Altitude Speed of Sound Chart? To make a long story short, I live at approximately 4000 ft. above sea level. I found a balistics chart and ran some numbers for the 40 grain .22LR at 1085 fps... (Not sure I did everything right with the chart), anyway, the results say that...

There have been several recent discussions of density altitude. There is at least one commercial firm which will make ballistic cards which use density altitude for you, if you give them your load data - for a fee. But what if you are cheap, like me, want to change your load, or want cards for...
