I like it a lot. Good for looking for optional powders and running "what if" scenarios. It is somewhat of an art to use it effectively and requires calibration. I usually fire a few test loads over the chrono and then adjust the data to match my rifle. From that point on program tracks really well and gives me a much better idea of chamber pressures being generated. All things considered, it is an astonishing bit of kit. I do use optimal barrel time which works with most but not all of my rifles. I really like sitting in front of a boring TV show and playing with QuickLoad. It has really aided my understanding of ballistics and made me a much better reloader. You will probably have to read or watch a lot of tutorials to get you up and running effectively.
