If you have not gotten one already, get one of those Redding case sizing dies that completely remove the pregnant belly from the case. It is a push through sizer type die.
As said, stay away from cast but plated do fine and are cheaper than jacketed usually. At least plated do not cause a problem with HKs which are in the same boat as Glocks regarding the use of cast bullets with their polygonal bores.
As to a specific load I cannot comment since I do not shoot enough 40 to make it worth my time reloading.
