To answer your question...

I back out the bullet seating die so there is no crimping at all. Approx. one full turn out.

For the Factory Crimp Die... turn out the crimp aduster a few turns to start... then I adjust the die so it just touches the shell holder, Tighten the lock ring. Place a cartridge with seated bullet into the shell holder. Run it up into the die all the way, then turn the adjustment down until it touches the mouth of the case. Then, run the cartridge out of the die and I adjust the crimp in about 1/2 turn for a light to medium crimp or you could go 1 turn for what would be a really heavy crimp. Then crimp away.

I load my 38 Spcl & 357 mostly with lead bullets, in which case the Lee FCD with its resizing feature is problematic. I "fixed" the problem by knocking out the resizer ring.I have two sets of 38 dies, one is used for 38 Spcl, the other is for 357, it saves me a lot of readjusting. I follow Iowegean's advice and seat & crimp as separate steps.

From Iowegan:
When I load .358" lead bullets, the full length post resizer squishes the bullet diameter down to .357". This results in bore fouling
. That's my experience too and mostly all I shoot are cast bullets sized 0.359" to 0.360" which works very well in all of my .357's including a Marlin 1894 CS. Rod
