Actually I would argue that it really depends on how many calibers and bullet wieghts you are shooting.
I load for about half a dozen calibers, and three to four different bullet wieghts in each caliber. This is excluding coated and uncoated variants of the bullet. (9 para, .222 Rem mag, 7.62x39, .260 Rem, 8x60S, 6 BR)
I reckon that QL has actually saved me a lot of range time, trying to find an accurate load for my rifle that would work.
I can work up a load that should theoretically be accurate in a given rifle, and then work from there. Normally it takes me 3-4 groups to get the best accuracy at most.
Then it is off to try the various powders... so in the end I reckon QL actually pays for itself.
And ofcourse there is the advantage of being able to spend endless hours tinkering with it.
