Hi Y'all,
Been away for a while (not the greybar hotel) on personal matters and have started back reloading again.
I'm reloading .32 auto and bought a pound of Titegroup as recomended on the Lee data sheet. It calls for .15 on the autodisk powder measure and a starting grains of 2.0 and never exceed 2.2 and dipper#.17 min oal.978. The smallest hole in the disk weighs 3.5 grains powder. of course i won't use the disk and i weighed the powder on the scale to obtain 2.0 grains and test fired them and they seemed ok. I can't do this with every load. I'm using 71 grain jacketed bullets. I used the titegroup for the fps of 978. I have some green dot but the data sheet says 810 fps. So the question is how do i compensate for the lack of hole size in the autodisk and still get the velocity of 910 fps. Any help would be appreciated.
 
You need to get a Micro-Disk for your Auto-disk.

Micro Disk and Spacer kit - #90302 - $9.98

BTW: It is very unlikely you are getting 978 FPS with 2.0 grains, or that you can get it with 2.2 grains.

Lyman #49 shows 71 grain FMJ out of a 3" Mauser HSC.
Tightgroup Powder
2.0 Start = 744 FPS.
2.3 MAX = 849 FPS.
