beerbelly, this is how I adjust my Redding dies, and it souldn't make a difference, weather their Lee,Redding,RCBS,etc.
With the seating die, I run the ram all the way to the top,shellholder and empty brass in place. I screw the die down, until it contacts the case. Then, I back it out about 3-4 turns. This should leave you room to adjust the actual seating stem down. I have the seating stem almost screwed all the way out. After putting powder in the case, seat the bullet, run the case up into the die, screw the seating stem down until it makes contact with the bullet. Depending on how far down the bullet needs to be seated, screw the stem down. If its a short bullet like a 125gr. in a .38, I might screw it down a few turns untill I get close to the cannalure,or crimp groove.
If, I can't screw down the seating stem far enough to seat the bullet where I want to, then, I'll loosen up the die, and re-adjust the main body down a turn or 2. Then readjust the seating stem. If, you can't get the main die body screwed down far enough with wrinkling the brass, get a longer seating stem. gypsyman
