Had the keyholing issue with my CZ too.Only thing that completely stopped it was going the powder coat route.
Ok, so I measured my dies, the expander in the lee 9mm measured .355, the expander in the 38 special dies measured .357. Used a couple of small metal spacers in the top of the die and put the 38 expander in the 9mm body, ran through 50 or so pieces of brass and primed and loaded with 3.2 grains universal powder. Seated to 1.080 which seems to be the sweet spot when chamber checking the loads. Tested today and I am pleased to report no keyholes. Ran them at today's IDPA match, excellent accuracy. Ranges were from 7-18 yards and windy as hell. Very soft shooting compared to the too hot loads of titegroup. Only complaint is that universal powder will not meter worth a **** in my RCBS powder dispenser. Always something lol...
Guess I am ordering a M die for 9mm.
Glad you have your system working. Enjoy.
