Need info on any single grain increment BP revolver powder measure.

the fill tube is about 3/8ths diameter

Interesting! My 5~55Gr in 5 Gr increments is exactly that diameter
I wonder if this isn't just a marking change to a 5 Gr one as it has the identical diameter? Those 1 Gr marks must be really close together the 5 gr ones on mine are only about 1/8" apart!

(Mine is very similar to the Dixie one from the post above, but without the funnel.

I have both 5 and 1 grain marked measures, the only difference is the veneer scale on the rod, same body and size.



1-3 grain changes in the powder charge well not have a visible effect on accuracy. To optimize accuracy work on consistent seating depth and pressure. A loading stand with a adjustable ram well help this. Be sure and place the rb so the spur is in the same place every time, I like mine facing straight up.

I admit I messed with my load, tweaking till I got the best accuracy I could, then I cheated!

I scribed a line on the back of the scale slider at the point where everything "came together" It seems to be 29 Gr as near as I can tell.
Then I bought a 30 grain powder spout, & measured it (28 Gr, Curses!) Used a chamfer/deburr tool from the reloading bench to taper the sharp shoulder inside the join with the flask & spout (30 Gr Drat!) & finally filed & chamferred/deburred the tip of the spout to 29 Gr (whoopee!).

What I do now is drop the 29 Grs into the measure which is set to 30 Gr. If the dispensed load JUST stops shy of the top of the cavity I have a good load & have a buffer for safety between the flask & the cylinder.
