I noticed in the Midway catalog that some powder dispensers are not recommended for use with extruded powders. Can anyone tell me why and what is an extruded powder?

Damn! I posted this in the wrong forum. Would someone please move this to the reloading forum?

Well, maybe I can handle that question. Extruded powders are made by pushing the powder mixture, which is like a dough, through fine holes in a screen. It is exactly like making spaghetti or macaroni, but on a smaller scale. The powder granules look, in fact, like tiny spaghetti or macaroni, as they are short rods or tubes. The gray color is a coating to control burning and feed better through measures.

The other type of powder in common use is ball powder, which is made a different way and is in small balls; these are sometimes flattened slightly. They are similarly coated.

All measures work better with ball powder, but some don't work as well with extruded powder, having sharp surfaces that cut grains and hinder the operation of the measure.

There is also flake powder which looks like ball powder granules which have been pounded or pressed flat.

A few examples of extruded powders are in the IMR family, say 4831, 4350, or another would be Varget.
I usually set the measure up to throw short and trickle up to weight.
Forget using this in a progressive.
