Guess I've been working up this question for awhile now.
OK, in the short time I've delved into hand loading (since November 2008), I've amassed a few tools, books, lead supply, brass, etc.
I quickly went from "most velocity and power" loader, to a "highest accuracy" loader.
Doesn't matter how much power it has, unless you can consistently achieve target I've found.
So, in loading for the .223 Remington, I found that the Lyman "Potentially Most Accurate Load" recommendations have some merit in my own shooting. A cartridge I made using those recommendations, has surprised me with it's repeatable, reproducible results in 3 firearms chambered for that.
Also found the same to be true in certain pistol cartridges, notably 10mm.
That brings me to the question, that hopefully someone here has insight into. Are those PMAL recommendations determined via empirical (real world experiment) results, or are they the result of an internal ballistics calculation?
This leading up to desiring a method, by which I could reference a given cartridge, bullet weight, and powder type, and have my own PMAL purely by predicted calculation.
Moreover, is this a function of QuickLoad? I've been considering purchasing that program as of late, and just wondered if it had provision for PMAL recommendations.
Thanks to all for reading my request here.
