[QUOTE="bigedp51, post: 1457523, member: 28965"] The information I sent to you shows tweaking the burn rate and if needed tweaking the bullet weight very slightly. And as long as the chronograph velocity matches the Quickload velocity it means the chamber pressure is a very close guesstimate to actual chamber pressure. Just remember it is only a software program and it must be adjusted and tweaked for every firearm and the components used when reloading. Example below A brand new Savage button rifled barrel bore scope photo. [IMG]https://i.imgur.com/GpTCke2.jpg[/IMG] And below a custom hand lapped barrel. [IMG]https://i.imgur.com/S82Lb6S.jpg[/IMG] Bottom line, Quickload doesn't know what type finish your barrel has or its actual bore dimensions. So you must adjust and tweak Quickload to get approximate answers. The throat in my Savage .223 is longer than the throats in my AR15 rifles. And there are no adjustable throat variations in Quickload between .0250 and .0500. And my Savage throat length is .0566 so thats a lot of burn rate adjustment tweaking Quickload. When I first bought Quickload I did not have a chronograph and was disappointed how far off the default settings were from the reloading manuals. And when I did get a chronograph I still didn't think much of Quickload and having to make adjustments to it to get close to the reloading manuals. After this its more money buying a Pressure Trace System and getting more accurate pressure readings. BUT its the strength of your cases brass and construction that ultimately governs how hot you can load. And Quickload doesn't tell you that either and your Federal primer pockets will stretch out of shape sooner than other brands of brass. Call me old fashioned but nothing beats making a workup load and reading the brass and primers for signs of pressure and also measuring base expansion just above the extractor groove. [/QUOTE]
