I absolutely love the software.
Redneck2: the software comes with Quick Target (mine did, but got the original version a LONG time ago), you can pull your load data and gun data from Quick Load into Quick Target and see what the trajectory is.....bullet drop, bullet drop with various zero distances....heck, you can even imput optic info and it will tell you how many clicks you need to adjust for various ranges......While it still takes real world testing, it gets you really close.
I am currently using Quickload to help me figure out some far from traditional loads. I am loading heavy 308 projectiles in a pistol cartridge for subsonic shooting....and trying to find a load that will also cycle the semi auto rifle. So I am loving the aspect of quickload that will let you see the pressure at various points in the barrel. up to this point, I have always shot commercial of surplus ammo so do not really know what pressures I need at my gas port to make this thing cycle.....once I find a load that just runs it, I can go back into quickload and see what the pressure is at that point in the barrel, and that is my magic number. After that, any future loads, I will just check and make sure my pressures at the port are atleast that amount.
There is NO published data for what I am doing. there are a couple of others out there doing the same thing with the same cartridge.
