Trailboss powder

[ruger22]

Trailboss is a good "practice" powder. It is not a powder that I would hunt with or do serious target shooting with, but for younger people, my wife, and for load that one can shoot cheaply , it cant be beat imo. The recoil is very light.I use Trail boss in a 3030 and others. It works great with cast bullets. I use a lee dipper to measure the stuff as it doesn't meter well in a uniflo. I found some at Jo Brooks in Brandon

I have run through many pounds of Trail Boss with a Dillon 550.
From 38 sp to 4570.
Never a problem.

Is the powder set up on a Dillon what you are calling a uniflo?
