[QUOTE="Wile E Coyote, post: 586902, member: 28381"] I was out over the weekend with my .223; a rifle that shoots very well and I have my dope figured out in a notebook out to 655 yd for a 60gn Sierra HP. Data developed with a lot of "shoot n see." But it is hard, accurate data and I trust it. Good chrono data has been determined and tested with the G7 calculator so I knew what to expect. I left Exbal in its default settings and just input my bullet, velocity, sight info and the weather at the moment. the one change made was to set the altitude to 0 and use station pressure for "pressure at altitude.". The drops generated by Exbal were almost exactly what I had already worked up. Out to 425y everything was within a click (1/3 min). At 485 the deviation opened slightly, 2/3min but the wind was starting to pick up. I'll pick this up again next week and shoot out to my known 655y on paper. I do need to use the program a little more to make it second nature as I did spend more time with it than I would want to when hunting. Otherwise I'm confident that it will produce a good dope provided I input accurately. [/QUOTE]
