[QUOTE="bigedp51, post: 1387222, member: 28965"] You need a chronograph to get close estimates of velocity and chamber pressure. You adjust the burn rate in Quickload until the velocity matches the chronograph. On top of this you need the case capacity from a fired case from "your" rifle. Quickload defaults to the least case capacity of that caliber. And I have seen as much as 6,000 psi difference in chamber pressure in cases with the most case capacity. There is simply too many variables in firearms and reloading components for a software program to output accurate data without adjusting and tweaking it. [/QUOTE]
