Modeled up the Lee 356-102-1R and verified the model against both a Hornady 380 Auto gauge and the barrel from my 380ez.
Interference detection in Fusion gives me the same COAL in the Hornady gauge (modeled chamber is SAAMI minimum spec)
Bullet profile measured with Starrett radius gauges.
Some eye candy just because no thread ever has value without gratuitous image content

TLDR - Lee bullet mold profiles suck. I don't think they look past cherry cost when designing a profile.
