Dare I say it...use a FCD. I *must* with my LRN and CZ, otherwise they won't chamber.
I don't use an FCD, and my 9mm are home cast .358" and chamber perfectly. And reliability is important because they're for IPSC use.
Anyway, we all know now that is was an OAL problem after all. Since different bullet profiles and ogive shapes are ... well... different, OAL must be tailored to the specific bullet and NOT
to the caliber + bullet type. This is why we use our barrel (off the gun) as a gauge to figure out the ideal OAL for loads using new bullets.
