Lookout...I've got QuickLoad v3.8

[Ridgerunner665]

All I can say is...why did I wait so long to get this?

Been immersed in it for a couple of hours now, lol....soooo much information!

Yup! Herr Broemel deserves every accolade he receives for providing this program.

Oh yeah, stand by for heavy waves! QL is addictive. Just when you think you have something the way you want the nefarious QL undoes it with it's mythical numbers!

Congrats. Awesome program. I blame Mike for my addiction!

You have to get in line behind some others. :grin:

Yep...your weekend is shot.

 

[Dwh7271]

It's pretty cool, and addictive.
The what ifs can get to be pretty fun.
I had to raise my hand and get one of the guys here to help me once.
Now I'm dangerous with it. :lol:

QL is one of the most enlightening things to ever come down the pike, IMO. I can spend hours at a time just playing around with this and that. Of course, it's a lot like a chronograph in that every answer you find just prompts a few more questions!

True, true! A veritable time sink. :grin: To paraphrase Patrick McManus, "This hand loading is a fine and pleasant misery."

Ridgerunner, does the updated software include Accurate LT-32 in the powder database???

No...not in there.

 

[RiverRider]

Bummer. I wonder why in hell not!

I probably shouldn't have bought this program. I'm not real computer program savvy and usually get frustrated trying to figure it out. The high usage of this program and my lurking on this forum are responsible for me getting it. Dang it another bunch of enablers for my addictions here. :mrgreen: I've noticed that there is no input for a brass maker. Should I be relying on the case capacity window for this parameter? Also I can't figure out how to get the print out like I see posted on this forum for a particular powder. Sorry to hijack.

Yes...

Weigh a fired case, note the weight...fill that case with water, weigh it again...subtract the empty weight from the filled weight...and there is your case capacity.

Mustanggt, welcome aboard; or perhaps I should say, "Welcome to the madness!" Good to see that enabling still works. The program is somewhat demanding, primarily because it is not intuitive. Read the manual from the DVD you received. It is really helpful. If you have specific questions, don't hesitate to ask. There is always someone willing to give a hand. When you get the case volume, it is important to use deoxygenated water. This is easily prepared by letting a pan set out open to the air overnight. Then, when weight the case, fill with a pipette until you form a convex meniscus. This is the value for determining Maximum Case Capacity, overflow. If you'll explain what in particular you are looking for in your printout, we'll try to guide you through it. Once you have the basics, you'll be addicted like all the rest. Here, have another cup of Kool Aid. :mrgreen:

Just copy and paste it...

 

[Ridgerunner665]

The thing thats confounding me is "weighting factor"...

I understand what it is and what it does (or at least I think I do)...but the factor it gives as default for many rounds just doesn't compute to me.

Rounds such as 7mm Rem Ultra Mag having nearly the same default factor as the 45-70?

Whats up with that???

 

[DrMike]

The "weighing factor" is an estimated value. It is a value representing the movement of the propellant mass with the bullet. In part, this value is dependent upon jacket material, barrel materials and bore profiles. The value cannot be constant as the propellant mass is changing along the length of the bore. The default 0.5 value is consistent with most bullets, though with monolithic bullets, this value may be increased slightly.

 

[Ridgerunner665]

The "tooltips" info is what confuses me...mentioning defaults for "straight walled" and "overbore" rounds...at opposite ends of the spectrum...then giving the 7mm RUM and 45-70 the same default factor.

 

[RiverRider]

Actually, that's not quite right DrMike. The mass of the powder may be converting to gas, but the mass is not changing. What the weighting factor is about is the amount of powder that follows the bullet down the bore before it's converted to gas. The powder will form a "plug" behind the bullet and travel some distance down the bore, but the more powder that is trapped in the case the less it tends to do so. The "plug" tends to be about the same diameter as the bullet, so the more overbore the cartridge is, the smaller the "plug" in proportion to the overall charge. The weighting factor can be manipulated in QL.
