Trail Boss might only be 9 oz. for the same price or close to it, for the other powders but I really like that it fills up the case to where you can see it and a double charge is impossible due to the density of the powder.

It works great in my 357 mag and 38 spl loads with all the lead bullets that I have tested and in my snub nose, I will keep loading and buying this powder since the standard Alliant and Winchester powders have yet to even come close to this..........................
