[QUOTE="Michael Eichele, post: 131613, member: 1007"] RSI defaults the pressure to the standard at the altitude you select and shows this on the drop chart. If you were to enter the default pressure for 0' according to Sierra (either 29.92 or 29.53) you will see a much closer match). Or enter 0' and 24.52 and you will see this same match. This is why the reloaders archive is set up so that it cannot be screwed up. If you use raw pressure, you DO NOT get the option to change the altitude to anything except 0' [img]http://www.hunt101.com/img/457582.JPG[/img] [img]http://www.hunt101.com/img/457583.JPG[/img] [img]http://www.hunt101.com/img/457584.JPG[/img] You can see that depending on what you select, things dissapear and reappear and the values of anything that dissapears change to a default such as 0' for raw pressure and 29.92 if you select altitude but dont know the area pressure or you can choose between actual altitude and area pressure (not raw pressure). It spells it out for shooters. I know there was a time I didnt know the differance and came up with faulty ballistics many times. Also, below is the latest progress.
