[QUOTE="Mikecr, post: 2930824, member: 1521"] Most scope makers make generalizations about their adjustments. So then their MOA is not actually 1.047 inches per 100yds (IPHY). It's easy to test, and hopefully your software allows you to enter your actual adjustment value. Atmospherics are also important to BC. You need to account for this. If anything, check your local airport weather conditions, enter it in software. Where it gets tricky is your entry of BC. Depends on the software. Sometimes when you enter BC, it can override local BC. The software may assume that you know that the BC you're entering is correct, right now, regardless of other entries. Ideally, you would enter factory declared BC and check a block for what air density conditions that BC is based on. Std Metro, Std. Army, or ICAO for example. Then, as you enter local attributes which would affect that BC number, the software would internally adjust BC for that. Take the time to look into & consider what your software is doing. [/QUOTE]
