Well... I chose that word carefully so not to imply that the output of QuickLoad should be taken as 'gospel', as so many people are wont to do with the data presented in reloading manuals. However, anyone that has ever used the data from a reloading manual has either used data "predicted" from the manual's author's calculations, or they are "predicting" that thier rifle will perform similarly to the rifle used in generating the reloading manual's results.
It has been my experience, that while QL tends just slightly to the conservative, it is head-and-shoulders above any of the reloading manuals I have used over the past 40+years in predicting the results I actually get at the bench. If you choose to disregard QL's "predictions", it's certainly no skin off my nose, and I remain interested in the outcomes of your actual testing.
