I use close to the same load as bb57, but with red dots brother, blue dot.

So a 158 LSWC (Tumble Lube variety) over 6.2 grains of blue dot. It meters like ****, so I use the Lee powder dipper, .3 cc x 2 for each load. DOUBLE CHECK WITH YOUR SCALE!!!

This is the most accurate load out of my 327 TRR8. In fact, most accurate handgun load I have out of any of my hansguns, the 10mm, 44 mag and others feel neglected.
