[QUOTE="bigedp51, post: 1471702, member: 28965"] You need the case capacity of your fired cases and then you have to change the burn rate in Quickload until the velocity matches your chronograph. You will then have a computer generated guesstimate of your chamber pressure. There are too many variations in firearms and reloading components for a software program to be as accurate as a pressure test barrel or a strain gauge. If your load is too hot your primer pockets will tell you to back off. And Quickload doesn't know how hard your brass is or how thick your flash hole web is in your cases. Example below, the Federal case has softer brass and has a thinner flash hole web. And cases with harder brass and thicker flash hole web will take more pressure before the primer pocket stretches out of shape.

He increased the load until he got brass flow into the ejector and then backed off one or two grains of powder and called that max for the cases he was using.
