Lee Disk (???)

you need a spread sheet for the disk!
Click to expand...
You don't need a spreadsheet I just had it so if I wanted say 4 gr of HP38 I could look and see I probably need the disk with the .37 hole.
gr*vmd=cc
so for HP38 4*.0931 =.372 ( .37 disk)

You can work out an actual vmd for a powder by
cc/gr=vmd

Some listed vmds are close some are not and vmd can vary a little lot to lot.

how in the heck am I supposed to do with all them numbers? I can’t ever figure the timer on the oven?

is this your data?
 
Some of the VMDs are calced by me WSF as an example some are listed.

Here is the sheet, page 2 is the calcs
some listed vmds are on another page

If you put the powder vmd in cell K1 it calcs disk size for various charges
Again some listed vmds are close some are not.
YMMV

PS: No macros in the sheet

And the beauty of Auto Disk with DIY $1 brass screw mod is that you simply select the next larger hole that will meter slightly more than what you need and incrementally reduce powder charges by turning the screw until you have the "perfect" amount of powder charge to produce smaller shot groups.

And unlike regular powder measure that you have to change the setting for other powder/bullet weight applications and keep weighing until you have the charge drops verified (And weigh every 50-100 drops to prevent drift), Auto Disks are cheap and I have several sets so I can "set" the DIY brass screw mod and "leave it" for my particular favorite load and use another disk for load development or another load.

So when it is time to load my favorite 9mm/40S&W/45ACP "perfect" loads, I just grab a "pre-set" disk and drop a few charges to settle the powder in the hopper/until the drop charges are consistent in weight, then go to town and load 1000-2000+ rounds without worrying about powder charge drift.

Life is good! :p:thumbup:

My most recent lot of No.2 has a measured VMD of 0.0962 and the previous bottle was 0.0838 so it can vary a good bit lot-to-lot.
 
look… later tonight, going to grab some hp-38, grab hole #.37 and see how many 4.0g I can get. Lets do 10, then you nerds can crush the 6/Sigma, Bell Curve, SD, and do a flow chart for a $30 powder drop…

interesting side note: midway lee prices are, New Drum is $24, and Pro Disk is $40

No, fill the hopper and lightly tap hopper 10 times to settle the powder.

Cycle the AD enough times to get consistent drop THEN do 10 drops. :)

that’s how I do all my drops! get it consistent then start the official drops

chain bead does the powder dropping? and not a heavy spring?
Click to expand...
Heavy spring was typically used for Turret press so powder measure could go round and round.

With Pro 1000/Load Master that used rotating shell plate, stationary bead chain provided slower smoother cycling of disk. I used Pro Auto Disk with both bead chain and heavy spring and prefer the bead chain.
 
Just did 10 drops and this thing is CONSISTENT!!! did not deviate at all!!!

problem: powder spill, the plastic hopper screws thread are striped, so I used teflon tape one the thread. Will be looking into a new hopper.

This thing is BEAST!!

Pro model autodisk clears up most of the leakage issues.
Also solves the problem of putting screws in to the plastic hopper.
The pro model has machine screws attached to the hopper and nuts screw on the bottom of them so the hopper getting stripped issue is solved.
Wiper helps stop the leakage.

I seem to recall you can use a little (not much) bigger and longer screw if the holes in the hopper are stripped.

If you end up liking the disk measure you would like the pro model better, it solves issues with the first design and uses the same disks.
Livelife's screw mod is handy to get a charge you want if the correct size hole is not available in a disk..

?? Don't understand the question.

If you used the .37 disk and were after 4gr its looks a little off. (so your VMD is not .0931 but a little different)
If you weigh that charge you can figure out your VMD for your lot of powder and then use that to get a better idea of what each disk hole will throw.

When I was using the disk a lot I would use like 3 disks .4, .53, .71 throw charges from each, average them for that size hole, then work out the VMD for each hole then average those
to get a VMD # for that lot/type of powder.

disk hole in cc (.37) / charge = your VMD

your VMD * powder charge in gr = disk hole size in cc

Not tricky 3rd or 4th grade math;)

You can always just put in a disk and see what it throws to begin with but with the old style measure every time you change disk you take the screws out of the plastic hopper
so less changes are better. (which is why I made the sheet in the first place)

I have a gaffing tape Mod, I want to try! the little bit of spill don’t bother me if it’s that consistent! this thing is so good, I’m buying a pro model
 
Another option is to order the "Update kit" to essentially upgrade your regular Auto Disk to Pro Auto disk for $21.49 and includes following (And free Charge Bar as a bonus. It's back ordered but will be back in stock 12/2/22) - https://fsreloading.com/lee-precision-pro-auto-disk-upate-kit.html

So you can use the AD for now until the upgrade kit is available.
