Any recommendations?

I have an old RCBS thrower. (40 yrs with me)
Also a #55 Lyman thrower (new to me)

Will either or both of these throw 2.0 grains of Bullseye accurately and reliably?


Next question:
How do you check the weight?
I have a couple very good beam balance scales.
Are they accurate enough for such a small amount?
Would a digital scale be any more accurate for that small amount?

Thanks for you help
 
I run the Lee manual powder thrower for that load in 38 Smith. After I get it dialed in on an average ten loads I just check every tenth load.

Any verified good beam scale will work.
 
Check what size drum your rcbs has, if it a uniflow them it can be a small (pistol) or large (rifle drum).

What are you reloading that needs only 2 grains?
With the current powder price reloading with only 2 grain would be sweet lol.
 
32 SW long
Should get 3500 loads from a pound...lol

I’ve never loaded pistol rounds before so it’s a bit new to me handling such small amounts of powder.

Going to be all single stage.
 
For consistent measurements of very light loads, you should try to find an Oahus Do-O-Measure. I too do/did 32 S&W long with VV N310 so even less than 2 grains. This was the best one I could find for this purpose. Second best was the Forster Bench Rest powder measure which I use for the small bullseye loads.....little finicky to set up but so consistent once done. You might find a Du-O measure on Ebay.....
 
Found a small Harrells powder thrower for $40 at a gunshow. Turns out to be one of my best deals ever.

Works great for small amounts but like every measure it depends on the powder. Not great for unique or 800x wich does better in the Lyman 55. For fine stuff its amazing when you get a nice consistent method.

When working with such small amounts it seems pretty much to depend more on the type of powder than the specific tool. Cornflakes just don't flow as nice as sand and in a 55 gallon drum it matters less than in a shot glass.

Dippers can also be very accurate and custom sized by adding glue, filing down or constructed from shells with a handle soldered or glued on.
 
Thanks for all the tips.....I will BOLO at the next gun show for some of these measures....

In the mean time I am going to try the Lyman #55. I think it will do it.
I wish I had a 5 or 10 (or both) grain check weight...any ideas?

I have a Lee Auto Disk for my .32s. Even the smallest holes that came with it were too big, so I filled a couple of them with epoxy and drilled smaller holes.

Lee used to make a micro disk for very light loads in the Auto Disk powder measure but they seem to have stopped producing it. I use mine to drop 1.8 gr. of Bullseye for 98 gr. 32 S&W Long target loads and it works very well. I seem to recall someone selling a knockoff micro disk on EBay but if you can't find one then modifying a regular disk as noted above should do the trick.

I've been in the situation where the best load was right in between two hole sizes. I didn't feel like using the adjustable powder bar everytime, so I just drilled the smaller of the two sizes part way through to drop the just right amount of powder. I also took some red hobby paint and marked the volume indication on that particular disk.
 
You could sacrifice one of your 32 shell casings by twisting on a wire handle and cutting/filing it down to hold 2.0 gr. For accuracy scoop out ten charges and weight them, divide by 10, to check weight. So 21.5 gr on ten scoops = 2.15 gr file some more.

Both Lyman and RCBS offer a full check weight kit. It's not expensive and I find it extremely useful for these small loads. I primarily use the Ohaus 505 scale and I also have a RCBS 5-10. I set them both up for that small weight (1.2 to. 1.4 VV) to be doubly sure I had them set correctly. Once I've done that to start the loading, I just go back to the 505......Maybe I'm too fussy or the other 3 letter acronym.
