I bought the RCBS Rockchucker Supreme kit some time ago.
The Uniflow powder measure was included. This measure threw very repeatable and accurate charges of H4831 for my 300 Winnie, but it seems to be very inaccurate with small charges of flake type powder.
I discovered this while loading target .357 HBWC loads in the range of 3.5 gr Bullseye. The throw cylinder frequently acted like it got clogged or had to cut powder to finish the throw. Powder throw varied as much as 0.5-0.7 grains...my velocities were all over the place when I got to the range. This could be a serious shortcoming when experimenting at the upper end of recommended loads.
Now, short of a powder trickler, is there a better way to meter this kind of charge?
Help!
Thanks,
Rich
