If that 105 grain bullet is the Lee #356-102-1R
Lyman #4 indicates the best accuracy was with Unique powder .
Starting Load : 5.7 grs. @ 1219 fps
Maximum Load : 6.3 grs. @ 1338 fps .

In the 9mm Luger with cast bullets I get my best accuracy with 4.7 grains of Unique powder and any/all the following bullets .
Lee # 358-105-SWC
Lee # 356-120-TC
NOE #358 -124-TC-GC

This is a load on the light side worked up for a WWII Walther P38 , I don't want to batter the old war horse and the 4.7 gr. load shoots to its fixed sights with all three bullets .
It groups the 105 SWC best of all for some strange reason .
All bullets are air cooled and sized .357 .
