Any one using 1/100th grain scale....?

My V3 resolves to about 4 hundredths and that’s individual grains of R26.
If you running big sticks of N570 or similar getting any more accurate would definitely be tricky.
Exactly, I don’t have the auto throw/trickler but I have the A & D fx120i. I manually throw the main charge and trickle up to the charge weight to the kernel of powder using a dandy trickler.
Most stick powders I use are between .00 and .04 for a kernel of say varget, Re26, Re23, H4350, H4895. So if you want that finer I’d imagine like you said, cut the kernels or what I was thinking, use a finer powder like a ball, flake or something.
Ok
Who’s gonna be the first to weigh out charges to the single hundredth or better of WST for their 45ACP?
My scale is accurate to .002 grams which is roughly .03 grains. My ELR results (SD/ES) are better but brass prep is probably more important than having this high of resolution on your scale.
I will say it’s difficult to get solid readings if: the AC/heater is running, I breathe too closely to the scale, my wife/kids open a nearby door to introduce a temperature swing.

I’ve noted that too about those powders and have learned the ways of my own scale. My system of adding or deleting 3-4 kernels has worked this long. I get single digit SDs on 10 shot strings most of the time. Sometimes 9-11 or so but works for me. Sub MOA to 1” accuracy in 10 shot groups. This was a recent one with 308 CBC brass that’s been fired 6-7 times at least and V43.5 out of a APO Savage.
People who measure to the hundredth are the ones who way the brass and every bullet and separate by lots. Is there really a difference between 42.6 and 42.612?

I have a Scientech SA-310 that weighs to 0.1mg which is .002 grains, and a Scientech ZSP-500 that weighs to 1mg or .02 grains.
To be honest, they don't get used much. My balance beam has an extreme spread of .09 grains and an SD of .03 grains. That is enough precision for what I do most of the time.
I did use my analytical balance to proof and accurize all my check weights. I have a couple sets of Troemner apothecary weights. I paid up for one precision calibration weight for the balances and then used a file and sand paper to fine tune the rest.

Yeah, my time’s worth way too much for all that. Of course, I’d you’re trying to be the best in the country in competition or are retired and OCD then more power to them.
I use a satorius entris, accurate to .002, It is very easy to weigh within one kernal of powder. Most of the precision type powders I've used are .015 to .03 per kernal. I bought the most accurate I could find after being sick and tired of having doubts of my hornady lock and load dispensers which will commonly be .2 grains off! I reload for PRS.

I would be interested to see how they are controlling humidity then. Humidity won't change the weight enough to notice with the scales we are using, but it will certainly change burn rate. The potential rate of change in burn rate is a magnitude more than the effect of a single kernel of powder.
The difference in BC from bullet to bullet is potentially more than the effect of a single kernel of powder.
We have reached the point in this hobby where we are trying to influence the whirl wind by the direction we are farting.
The overall advantage of the fx120i isn’t its accuracy, it’s the automation capability. With some simple wiring and programming you add an auto trickler and it does it all. You simply have to pour the powder into the case and put back on scale and it automatically starts going again. No one needs 1/1000th accuracy for powder.
If I did it over again I would probably buy the fx120i with auto trickler, but for me its about eliminating a variable. I know I don't have any doubts that all my loads are within one kernal of what I want them to be. No doubt that level of accuracy is not necessary, but it is piece of mind and yes I am a little ocd, but I don't weigh my brass or bullets... I do weigh my primers though... jk.
I agree
What it is good at is being super fast, super consistent and you don’t have to fiddle around with it like the RCBS and especially the Hornandy.
Throw your extruded in a coffee grinder and then use one of these.
Haha yes they are, even PRIMERS and separate......I can’t imagine going through all that!
I had a guy tell me he has someone reload for him and that guy does that......that would have to be an extra charge monetarily! Speaking of that.....besides components, what would one charge someone for reloading they’re freedom seeds? Do you do it by the hr or......?
I’m one of those people. You’re exactly right 42.6 vs 42.612 is practically the same. I’m ocd and it gets my rocks off
On a serious note, I’ve gotten better accuracy and consistent velocity by weighing my projos and brass in lots, and weighing my charge to the .03’s. I don’t do this for 556 or pistol rounds but I do for my stuff I use to shoot distance with. The difference is pretty small, but I sleep like a baby.
Hey, nothing wrong with ocd and definitely nothing wrong with getting your ROCKS offI’m one of those people. You’re exactly right 42.6 vs 42.612 is practically the same. I’m ocd and it gets my rocks off

!!Interesting, do you weigh the primers too?
Not at all. I used a small Hornady scale that came with the single stage press. All works well for me.

Nope. No weighing primers for me. I purchase match primers and pray to the CCI/Federal gods for blessings from the line worker that day.
I suppose you could do 1/1000 with Trail Boss. A 5.5 grain charge takes way longer to weigh than 93 grains of N570.
I use a Sartorius Practum and Mr. MacDonalds auto-thrower-trickler. The scale reports in 0.02 grain increments. The autothrower wants measurements in grains. For 308 my setpoint for IMR 4064 is 41.52 grains. I accept 41.50, 41.52, and 41.54. Anything else goes back in the hopper. With IMR 4064, 0.02 grains is a little less than one grain of powder. Given identical processing, Lapua brass shoots maybe 5% better than Lake City LR brass - trim, primer pocket uniform, flash hole deburr but no neck turn. I have a lot of LR so that is mostly what I load. Out to 700, I have much confidence in my scope settings - I can see the difference on the targets. I could sort cases but I don't bother. My shooting is crappy enough to make that unnecessary.
