Mccliff1971,
Welcome to the forum.
Ignore Mr. O'Heir's post after his first two sentences. He insists on making some things up and clinging to some kinds of obsolete information. QuickLOAD's own manual (and do read it all) tells you what its limitations are and who the author is. Mr. O'Heir has not studied either.
Yes, the Shooter's World powders (most of them) are in the database under their Lovex product numbers. Midsouth Shooters Supply and the Shooter's World website reveal those numbers. Just watch out for added suffixes not in the QuickLOAD powder designations as those may not match.
Bear in mind that all powder numbers have burn rate variation. The canister grades sold to handloaders have the least variation, but there is generally a tolerance of ±3% or ±5%, depending on the manufacturer. 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.
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. Then it often comes remarkably close. 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.
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. It's that simple. I've added in a lot of bullets that way. 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.
After the first two sentences, this is where Mr. O'Heir is wrong in the rest of his post:
1: 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. Ken Oehler has said he probably has seen and worked with more real pressure data than anyone else alive.
You can, when high precision is needed, match QuickLOAD's pressure or velocity prediction to published data by tweaking powder burn rates and other factors. There is a learning curve, but once you get there it is not only useful but provides a terrific education in the factors that affect interior ballistics.
2. The view that bullets are loaded by weight-only, regardless of the maker or design, is almost half a century out of date, as it assumes all bullets have similar construction and size and shape for a given weight, as was once the case with most jacketed bullets. The advent of VLD designs, solids, sintered bullets, flex tips and numerous newer cast bullet designs and coatings have rendered the idea obsolete. Allan Jones showed by direct experiment that employing the same bullet weight in different makes and designs and propelled by the same powder charge and primer in the same case, give significant peak pressure variation.
