I load my autoloaders with Unique and have had good success on
accuracy. Where the barrels are under 4 1/2" -5" (this also pertains to my non-mag. revolvers) I think this is a perfect all
around powder. For longer barrels and/or magnum revolvers I go
to Blue Dot or H110. (I have no longer barrel autos.) For many
years these have filled all my needs, even tho I have tried others which did work. After all is said and done, it is what works and what you feel comfortable with. I have not had any
'metering' problems with either, however, in my rifle powder, I
did go from stick powders to ball powder for that reason.
Happy reloading!!!
