There's a PVC fix for that at cast boolits
I went and ordered a M die.
I 'll resize on the RCBS RS3,then use the 9mm M die in station 1,then I'll raise up the powder funnel a bit to clear the M dies work.
The 9mm powder funnel in .353" dia, the 124 Dardas are .3565 to .357", I see almost .004" swaging effect and leading with that setup.
I would have tried the 357 M die,but it's set already in the Hornady L'n'L bushing. Just like the RONCO rotisserie,set it and forget it.
The RONCO thing actually works well.
