I guess my problem with QuickLoad is "Who says so?". For all the data that is presented have there been ANY actual calibration measurements? Where did the equations come from? Where did the powder burn rate info come from? Where did the science come from? Who says so? I'm neither for nor against QuickLoad. It's kind of expensive and I still don't know "Who says so?". Despite all the money I spend on shooting, I just can't justify this expense. For me... We have to assume that reloading manuals are providing safe data. Some manuals are clearly safer than others. Those manuals that have been scrubbed by lawyers seem to have the lower MAX loads but I might feel comfortable using any published data as long as I worked up slowly. Tens of thousands of reloaders use these manuals every day and most of them do so safely. So, I decided to go with Sierra for rifle loads. My pistol loads are middle of the road and just about any manual will do. Of course, my rifle loads are just middlin' velocity as well. I don't see the need to get anywhere near MAX. For me... Others may have a need for higher velocities but my suggestion would be to just change powder. Richard Wanna kill these ads? We can help!
