This is my favorite bullet for the glock 30sf
I use the Nosler 185 with Unique loading to a velocity of about 800 FPS. It is a very mild load and very accurate. The first group from sandbags at 25 yards put all 10 rounds into 2.5 inches with 8 going into just 1.5"!!!! I had decent results with 231 as well. The only downside with Unique is that it doesn't meter through a measure as well as other powders. I visually inspect each cartridge looking for powder variation. This usually seems to run about .2 grs.
