I am very fond of the Lee TC autopistol bullet designs--9mm, 10mm/40, and 45 are all on hand here. All three get seated with .020" of front drive band exposed above the case mouth--are given a mild taper crimp--and feed like water down a drainpipe in my centerfire stutterpistols. Bullet design is something Lee can get get right on occasion, though quality control on the tools using their designs can be uneven.
