O'Heir is wrong in the rest of his post:ġ: QuickLOAD's author is one of Europe's leading ballistics experts who writes software for the CIP and who not only shoots but of whom Dr. Bryan Litz's book, Ballistic Performance of Rifle Bullets is a good database of measured BC's you can use for a bullet your are adding or tweaking.Īfter the first two sentences, this is where Mr.
You can add any bullet to the database pretty easily by picking one that is close, clicking on the icon with calipers over a bullet and then giving it the new name and correcting the data and saving it.
#Quickload 3.9 download how to
There is a fair amount now published regarding how to dial the program in if its predictions didn't match published data very well for some reason. Your best bet, if load data is available with both pressure and velocity, is to compare QuickLOAD's performance prediction to those and adjust powder burn rate and other factors to dial it in a little more closely so you can apply it with whatever components there is no published load for. The database in QuickLOAD is built from measuring purchased lots without any way to know where in the tolerance range the test lot was, so it is common to have to tweak them by comparing to examples that are published to get some idea of the range of performance a lot you purchase may have. The canister grades sold to handloaders have the least variation, but there is generally a tolerance of ☓% or ±5%, depending on the manufacturer. Just watch out for added suffixes not in the QuickLOAD powder designations as those may not match.īear in mind that all powder numbers have burn rate variation. Midsouth Shooters Supply and the Shooter's World website reveal those numbers. Yes, the Shooter's World powders (most of them) are in the database under their Lovex product numbers.

QuickLOAD's own manual (and do read it all) tells you what its limitations are and who the author is. He insists on making some things up and clinging to some kinds of obsolete information.
