I was reading about fire forming brass with a reduced loads, and that got me to thinking.

I have a can of trailboss I was given. So I'm wondering, would Trailboss work for fire forming .223 brass.

I figured it would be a good way to use this powder up if it was safe and had enough pop to form the brass.

Anyone have any exp. with trailboss in this small of rifle cartridge?
