Q for those who use quickload

[kingfamous]

I had somebody work up some quickloads for me and I wanted to ask some of you some questions about how quickload works. The load was for a .223 / 68gr hornady match bullet, 20 " bbl. So it gave me the top 15 loads. Question one is how does it figure the amount of powder to use in powder type. Question two is that I use varget in my current load which shoots sub moa but it wasnt in the top 15 loads, why? Thanks for any help.

Quickload gives you computer generated guessimates, for the 68 grain Hornady 748 is one of the top powders because of the percent of powder burned is 97.7% in a 20 inch barrel. For Varget only 94.4 % is burned in a 20 inch barrel and this moves it further down the list. Quick load is looking for the most efficient powder for a given barrel length for its guessimates, BUT this doesn't mean Varget won't give you the best accuracy.

I have Quickload and it gives "some" good information, but the Sierra manual list 25.3 grains of Varget and its 69 grain HPBT MK as a accuracy load. And a computer guessimate isn't real world shooting results, and Quickload isn't worth the money when reloading manuals give real world data.

Some people love Quickload "BUT" if I had to do it over again I would have spent the money toward buying a MagnetoSpeed chronograph and gotten real data and not Quickload guesstimates..

bigedp51, I thought you said you borrowed someone else's QL and put it on your computer.

OP, I can't help with the exact answer to your question, because I am still learning how to use QL, but when fill in all the spec's accurately, I get within 10-40 fps of what my chronograph says.

Gi'day...

Depends on what 'optimization' you asked Quickload for.
Usually it's Nominal Maximum Pressure and Case capacity utilised (up to some value like 102%).
It's probably eliminated because it cannot approach nominal pressure with the available load utilization.

There is also a range of power speeds which will be considered (the slider bars at the top) - set too narrow or in the wrong range will eliminate interesting powders.

I find it's quite accurate and a very useful tool. But it doesn't help you decide what powder will shoot.
It tells you which ones to eliminate, and allows you to make guesses what a swap of powder might do.

But you MUST know the internal capacity of your cases - MUST, MUST. And the COAL is important as well.
One thing I must start to work on with it is to understand how good it is with the temperature predictions.
