Right now I am using 4.5gr of Unique w/124gr FMJRN bullet in the 9mm.
It is superbly accurate with mild recoil.
I have heard/read that the slightly slower burning powders do a little better in the 9mm, especially for accuracy.
I can attest to that theory, although I do not have any Bullseye experience with the 9 only 38 and 45, which works great in those calibers.
