So a while back bought a lee load master.
Had a major priming issue wont prime on it to dangerous.
So I pre prime and size and skip priming on the press.
Went shooting today shot about 200 40s&w had 4 low powder rounds and I'm sure it's the powder measure.
If I have to charge cases off the press I may as well use it as a boat anchor.
How do you deal with the lee powder measure?
 
I don't see any load data for H110 and 40sw on the Hogdon site. What data are you using?

As I understand H110 is too slow of a powder to use is most standard Auto loading cartridges. Barely recommended in a .45 LC. I'd look for faster powder more suited for 40sw.

First question, if it is so dangerous then why do you keep it? The theory behind a progressive press it to complete a round in one cycle, not multiple cycles or operations.
Second question, do you not visually check each case before placing the bullet?

Now, first off that powder is one of the nastiest measuring powders that I have heard of from nearly everyone that uses it. I do not use it. Every ball powder that I have used in both my Lee Auto Disk and Lee Auto Drum are consistent to within .1gr and I have been using them for years. They have been so consistent and reliable that for me they have become boring.

I have done a test for myself to judge my own ability and it goes like this:

While developing loads for handguns I would start at the beginning charge and work up .1gr at a time as many do. After many loads it finally struck me that I could not discern the difference it feel or shot placement between a 4.0 load and a 4.1 load or a 4.2 load and that if I tool 20 of each of those and mixed them together and randomly fired those in succession I could not tell you which one was which.

From there I did the same thing with the actual powder. I loaded up 20 cases with 4.0, 4.1 and 4.2gr and then with no bullet just open cases I mixed them all together and then visually inspected them. Once again I could not discern one from the other.

Now I also do not load to Max loads so a difference of +.1 or -.1 to me is irrelevant. But if you at loading at the bottom end a light charge may get you into trouble just as if loading to the Max end a heavy charge could also be problematic.

Still I look into every case before placing a bullet and what I am looking for is a powder charge, no powder charge or a double powder charge. After that I do try to discern if the charge is significantly heavy or weak and that is the best one can do with the naked eye.

I gave up on press priming on the Loadmaster too.
I then moved the powder drop to station #2 freeing up station #3 for a powder cop or bullet feeding die.
So there's that, and I switched back to the simplicity of the disc powder measure, but instead of the chain return, I use the chain arm and an extention spring connected to the die next to it.
That way I can move the disc measure to station #2.
Like this (on a different press)

And you can see the mirror I use to check the powder level on the right side of that pic.
Too dark to see the powder(?), add an $8 light:

That's what works for me,
:D
 
With the Auto Drum, make sure that the Clamp Knob (AM3041f) that holds the Drum in isn't too tight. With the hopper removed and a case in the shell holder, raise the ram and watch the movement of the drum. You want to see that the powder drum hole moves fully to drop the powder and then returns to the same point every time.

Are you sure?

We had a recent discussion of difficult to meter H110/W296 - https://www.thehighroad.org/index.php?threads/powder-measure-reccomendations.863943/#post-11399069

So I took my C-H micrometer/Redding micrometer/Lee Pro Auto Disk powder measures and weighed 10 drops after dumping 10 drops of powder charges back in the hopper to settle the powder and got following results:

C-H 502 micrometer:
  1. 9.70 gr
  2. 9.62 gr
  3. 9.62 gr
  4. 9.70 gr
  5. 9.68 gr
  6. 9.64 gr
  7. 9.78 gr
  8. 9.70 gr
  9. 9.64 gr
  10. 9.78 gr
Range - 0.16 gr


Redding micrometer:
  1. 9.54 gr
  2. 9.58 gr
  3. 9.64 gr
  4. 9.64 gr
  5. 9.56 gr
  6. 9.76 gr
  7. 9.66 gr
  8. 9.48 gr
  9. 9.58 gr
  10. 9.46 gr
Range - 0.30 gr


Lee Pro Auto Disk: (.61 cc disk hole)
  1. 9.16 gr
  2. 9.16 gr
  3. 9.08 gr
  4. 9.20 gr
  5. 9.12 gr
  6. 9.18 gr
  7. 9.16 gr
  8. 9.12 gr
  9. 9.08 gr
  10. 9.12 gr
Range - 0.12 gr

How do you know they were low powder?

H110/w296 is a bit slow for 40 but it’s also fairly fine and has been known to cause problems with measures as far as getting between things and binding.
 
The powder.. No I'm not sure I'm out of town.
Sorry for the confusion but in any case 1 out of 50 or so definitely has a low powder charge. I do check the powder think I need a light and mirror. Also I do have a new disk set up. Had one some years back remember a fair amount of spillage.
When the press is all working I just love it.
Have had success with 9mm. So once home will make some changes and see how it goes
 
What was your indication they were low, felt “funny”, had to beat the bullet out of the barrel, intuition?

I used a cheap inspection mirror and a flashlight and that worked fine.
