Absolutely worth every penny and much more.
Nothing else can tell you:
muzzle pressure and the associated "rocket effect" portion of recoil.
What powder produces the best velocity with the lowest peak pressure or muzzle pressure
powder burn % and load efficiency
a ranked order of powders with every imaginable criteria... muzzle velocity, peak pressure, muzzle pressure, total charge, efficiency, burn %, etc, etc...
What to expect if the powder lot you've got is a little fast, or slow
What do I lose (or gain) by going with a 20" barrel instead of 24", 28", 16"
Barrel exit time estimates, for predicting
"OCW" loads.
But the number one thing it does that nothing else can do (by definition) is give you load data that doesn't exist anywhere else.
Maybe you've got some 35gr V-Max and want to load them in .223Rem and can't find any data. Maybe you've got 55gr Nosler and want to load them in .243Win and want to know what powder might make the fastest speed. Maybe you've got a wildcat, like .243AI and there "official" data is almost literally non-existent.
QuickLoad is absolutely the best $150 I've ever spent on reloading gear, no doubt.
