Trail Boss & Loadmaster

[bgddy58]

Is anyone else having problems with Trail Boss powder dispensed from a Lee Pro Auto-Disk measure?

The cheerios seem to clog up in the neck of the measure, and even though I gently tap the dispenser before each stroke I am still not getting anywhere near a full charge in .38 Spl. cases.

I have tried both the disks and the metered insert, which apears to be essentially useless for Trail Boss. It has been a bot dry in SoCal lately, but I have been wiping down the measure with a cling-free sheet before loading.

Also, TB leaks from the Lee measure like a sieve - surprising, since it is coarser than most other powders.

Any suggestions?

Geez, I've never noticed it leaking, it is so honking big!!!

As far as squibs, if I load anything less than 3.5g or so, it will occasionally not drop a load, but from 3.5 on up, it works like a top. It meters as accurately as any other powder I have ever thrown.

Thanks for the reply. I have been trying to drop 2.8g loads for .38 Spl./125g bullets, but I can't get the Pro Auto-Disk Measure to drop more than (a very inconsistent) 1.7g average. As I mentioned, the metered insert has been useless; dropping only a tricle of powder to the bottom of each case.

Trail Boss will bridge hole diameters at approx .33" Maybe more ?
