1)5.0, 2)5.6, 3)5.6, 4)5.6, 5)5.6, 6)5.8, 7)5.8, 8)5.8, 9)5.8, 10)5.8, 11)5.2, 12)5.2, 13)5.0, 14)5.0, 15)5.0, 16)5.0, 17)5.8, 18)5.6, 19)5.8, 20)5.8

.46 auto desk. HP-38 Powder. Following are 20 separate drops using .46 auto desk and the weight of the powder drop. Before each powder drop, the scale was zeroed out with the case on the scale:
1)5.0, 2)5.0, 3)5.2, 4)5.2, 5)5.0, 6)4.8, 7)4.8, 8)5.0, 9)5.0, 10)5.2, 11)5.2, 12)5.0, 13)5.0, 14)5.0, 15)5.0, 16)5.0, 17)5.0, 18)5.0, 19)5.2, 20)5.4
Are you using the same case or a different case each time?

I am using the same case for all measurements and for both disks. I am cycling the press the same way for each drop.

In my limited experiences with the Lee disc system, usually the powder drop is lower than the minimum load. I just go up one disc at a time until I measure what I want. However, I did recently reload 9mm Makarov rounds using a disc with a larger cavity than the recommended disc (I did not have the recommended disk). The charge measured below the Max so I went with it. Range results proved a Super-Hot and accurate round. These loads were so hot that all of the cases were charred and there were a couple of unintended double taps due to recoil. It was fun shooting these rounds but I was a little more than concerned about over pressure. I was shooting a CZ-82.

4 pulls of the handle for each drop?

I think the comment was made because if you have any kind of breeze or you make any motion in front of the scale, it will add 0.2 gr or more if the scale lacks a wind screen.

What kind of scale are you using?

??? I am testing and attempting to get a consistent weight of powder. I am using a Lee Classic turret press. For each drop, I position the powder die under the case and raise the ram and actuate the powder action to drop the charge.

So, that's one pull for each powder drop. You can see just how inconsistent my powder drops are. They seem (at least to me) all over the place.

do you have your scale sitting on the bench you have your press mounted to? the vibration caused when operating your press may have an effect on your scale.

any air movement around your bench? fan running near by? AC vent blowing in the direction of your bench?

with a beam scale I could see the beam move when I had it sitting on my bench when I was operation the press or when the fan for the heat/AC kicked on.

I mountied my scale on a small shelf at eye level above my bench and had to tape of the vent under my bench to prevent movement.

I don't think you'd be able to see movement on a digital scale the way you can see it on a beam scale but try leaving your check weight on the scale when you cycle your press to see if your scale drifts.

Try running the press through a full cycle (raise/lower the ram and index to the next station, all the way around) with a different case for each powder drop and then check the weight of the powder only.

Running the press through the full cycle tends to even things out and seeing as the powder measure is actuated by the case as it drops the powder charge and flares the case for the bullet seating operation, using the same flared case over and over again may be causing some inconsistency in the powder drop.

Gpruitt54,

about the only other thing I can think of is if there is an issue with your powder.

how old is the powder?

was the bottle sealed when you first opened it?

have you kept it closed in a cool dry area?

pour some out on a piece of paper, is it clumped together?

what does it smell like?

take a pinch between your thumb and finger and roll it around, does it say in grain form or does it crumble?

thats about all I got.

There is too much BS going on here. The OP claims to be getting 5.8 grains of 231 thrown from the 0.43cc cavity. When I point out that this is impossible, he never addresses that. Then, later in the thread, he claims to be throwing 5.8 from the 0.49cc cavity (still impossible BTW). Either this guy is a troll and none of this is actually happening, or his avatar is causing him to be too stoned to know what is going on.

Check the charge just as if you are loading. When you load on a LCT you pull the handle four times for each single powder drop.

Besides that I see what Whisky is saying. My experience is that the AutoDisc throws light for the given cavity not heavy. Never had one throw heavy.

This was the last thing I purchased (this is my first time reloading). The container was sealed. Purchased the powder only 2 day ago. It is stored in the original container and kept in my dry and cool basement, where I do the reloading. I've accidentally spilled some on my reloading table and it does not clump. As far as the smell of the powder; I have no idea what it should smell like.

I've been so involved in responding to recommendations, I may have missed your contribution. In response to another suggestion, I tried using a different disk. As with the .43 and .40 disk, see the following so called impossible drops. Am I drunk or stupid; No. But I am interested in finding a solution to this issue. I look forward to any suggestions that can get me pass these issues. See the following test drops:

.49 auto desk. HP-38 Powder. Following are 20 separate drops using .49 auto desk and the weight of the powder drop. Before each powder drop, the scale was zeroed out with the case on the scale:
1)5.0, 2)5.6, 3)5.6, 4)5.6, 5)5.6, 6)5.8, 7)5.8, 8)5.8, 9)5.8, 10)5.8, 11)5.2, 12)5.2, 13)5.0, 14)5.0, 15)5.0, 16)5.0, 17)5.8, 18)5.6, 19)5.8, 20)5.8

.46 auto desk. HP-38 Powder. Following are 20 separate drops using .46 auto desk and the weight of the powder drop. Before each powder drop, the scale was zeroed out with the case on the scale:
1)5.0, 2)5.0, 3)5.2, 4)5.2, 5)5.0, 6)4.8, 7)4.8, 8)5.0, 9)5.0, 10)5.2, 11)5.2, 12)5.0, 13)5.0, 14)5.0, 15)5.0, 16)5.0, 17)5.0, 18)5.0, 19)5.2, 20)5.4

It could be some oil on the internals of the powder measure and discs. But I am convinced he is just not allowing the powder to properly settle by leaving the indexing rod in and pulling the handle 4 times to get the powder to settle and move into the cavity properly. Fill the measure full, tap the side several times. Pull the handle 16 times and drop 4 charges in the process before you weight the 5th. Be sure the die is set to slightly flare the case to be sure it is activated fully as well.

That doesn't explain grossly overweight charges, only underweight charges.

What scale are you using? Why you zeroing so often? Zero with the pan on the scale and don't rezero. Drop the powder in the pan and tap the case in the pan a couple times.

True. Hence my above post. I also wonder if he is reading the disc wrong. The way they fit in the measure could confuse someone.

This may be a silly question , Is the press bolted firmly down, is there powder on the press ? I've seen this happen. Your charges will be all over the board if the press is loose.
