9mm is more demanding than other pistol cartridges. The brass varies quite a bit from different manufactures. This makes it hard to get the same exact crimp pressure on each case mouth and therefore harder to get the same COL.
The Dillon powder charge should be +(-) a tenth of a grain. The only powder that gives me less accurate throws are big bulky powders like Red Dot, 800X, Trail Boss, ect. I have used a lot of TiteGroup with good results, except in one instance where I loaded over a thousand really small cartridges with 1.8 TiteGroup, or so I thought. Many of them got less powder and would not function. So, I would avoid less than 2.0 TiteGroup an any cartridge with the Dillon.
