That is true, their are things that are overlooked all the time. And one needs to understand everything they do.
That is strange.I've used Quickload for several years and use to think I was getting reasonable results from the simulation. It seems that after I bought an update to the component files the results I get now are way off.
I didn't think I could save my work. Seems like I tried to save sims when I first got Quickload and could not figure out a way to save it. I think I have one or two printouts I made during a previous load development. I'll see if I can find that and run it to compare.That is strange.
Had you saved your working loads prior to the update?
It would seem like you could pull up your past 22-250 file, and it would take you back to prior settings/components.
Is that the right barrel and barrel length in prior working order?
Are you touching the lands?
Please check me on this. I'm measuring the following to use in Quickload:I've been using QL now for about 7 yrs. In my experience every detail, no matter how small, concerning your components and rifle load will give you better end results. The more accurate you input the more accurate the output. JME
It's the second icon on the top row. Or go to "File" scroll down and "Save". You definitely want to be saving data or you'll be repeating the entire inputs over and over again.I tried to save sims when I first got Quickload and could not figure out a way to save it.
I think I'm about 0.035" off the lands at this point although I was having a hard time figuring out when the bullet just touched the lands.
You will know once you are able to push rifle long range. Most apps have correction when dialing up.Since ii started this thread I'm wondering if my Magnetospeed is having problem
Please check me on this. I'm measuring the following to use in Quickload:
Cartridge overall length
Bullet length
Bullet weight
Barrel length
Water weight capacity of the fired cases
Fired case length
Powder charge weight to less than 1/10th grain
Is there anything else I should be measuring?
Actual velocity then adjust the burn rate Ba to bring the predicted velocity to the actual.Please check me on this. I'm measuring the following to use in Quickload:

This is true. For example, a standard CC bullet needs a strt pressure in the 3000 psi area and Barnes about 6500 psi. This will vary with rifling, erosion, bullet length, bearing surfaces, bore smoothness. There are NO constantsI think Shot Start Initiation Pressure and Weighting factor should be tweaked before Burn rate. These two settings should remain relatively constant in your rifle, could change with barrel wear, and will change with a different load. These two are very dependent on your rifle and load. Then Burn rate to finish it, especially when changing lots of powder as that does change.
I don't disagree with this, but I'm not sure how to do that. I have been adjusting the burn rate because I know powder lot burn rates can vary as much as 10% lot to lot. I'm not adjusting so much lot to lot (although I certainly do that when changing lots) but I believe my adjustment is from the burn rate of the lot I am using to whatever is assumed in QuickLOAD. I would appreciate some education if this is not the best way to do this. Unfortunately, the QuickLOAD user manual is useless.I think Shot Start Initiation Pressure and Weighting factor should be tweaked before Burn rate.

Where did those numbers come from?This is true. For example, a standard CC bullet needs a strt pressure in the 3000 psi area and Barnes about 6500 psi. This will vary with rifling, erosion, bullet length, bearing surfaces, bore smoothness. There are NO constants
