So true..
I have a Lee Auto disk, and here is what I do.
First I will throw 10 charges and dump them back into the hopper. (This eliminates any inconsistencies associated with the 1st couple throws)
Then I will throw 10 more and will weigh them. (On my RCBS Chargemaster's scale.) This gives me an average of what each throw will be. (It will tend to minimize any discrepancies based on individual throws.)
If I don't like the average that I got, I will change the disk up or down to the next size and repeat my first two steps.
I will continue to do this until I get the charge that I am looking for.
Oh, and as others have said, wipe with used dryer sheets to minimize static.

Since Titegroup is a medium bulky powder all you have to do to get an idea of charge consistency is visually check the powder level in each case after throwing the charge. You will be able to detect light charges but I don't think you will have a problem with light charges at those throw weights. Occasionally I will have to go to the next disk size but that's OK. Titegroup will probably go up by about .3 grains per cavity so you're only going to go up to 4.2-4.3 which should be plenty safe and retain full gun function.
Your case should be fine to reuse.
Charge weights 4 grains and up should not have this problem. I found it goes away above around 3.5 grains.
I had just opposite experience. Using the adjustable charge bar the variation in charge weights (especially with charge weights under 3.5 grains) was just brutal, especially with bulkier powders like Promo, Red Dot, etc. Maybe it's OK with finer grain powders or higher charge weights but it was awful with bulky powders & low charge weights, much worse than the disks.
None of the flake powders meter very well in smaller quantities in any powder measure I have ever tried. Some are better than others but none are great. Unique, 800X, 700X, etc.
The crimping is also confusing me, I "think" I'm putting a slight crimp on but it actually has thesame diameter of about .422 or so at the case mouth as it does the base. And there's an area in between the base of the bullet (not at case mouth, but the line you get in the case where the bullet is seated) and the base of the case where the diameter is slightly less, around .417 or so. Is this normal? Can I blow up my gun from crimping mistakes? Haha
I think that the inconsistency Im getting in my COL is due to varying case lengths.. This seems strange to me since it's only once fired brass. The extremes in my COL's were about 1.126-1.315. Are these ok?
My loads are titegroup 3.5gr (10 rounds made), 3.8 gr (20 rounds made), 4.0gr (19 rounds made, put one primer in upside down so I soaked it in WD40) under a 165gr FCP TC campro bullets. They're far from the max charge (5.1) so I figure s little inconsistency in the COL should be fine for now until I start working my loads up to at least the minimum charge which is recommended at 4.6 gr of Titegroup. Sounding alright guys?
