I've found 8.5gn of Unique behind a lead 240gn RNFP is a sweet shooting & accurate load.

It does make a slightly louder boom than if you load with 6.5gn or whatever, but I've found with .44 mag especially, unless you create enough pressure to seal the case in the chamber you get terrible fowling down the sides of the brass, which is a real sod to clean off.

Cheers
