No crimp bullet seating of .45ACP

[JimGun]

According to my RCBS pamphlet that came with the die set, I should:
1) put a primed,powdered, casing in the shellholder and run the case up into the seater die. Then screw the seater die down until it touches the case.
2) Then back the seater die off the case for the space of about a nickel.
3) Then put a bullet in the case and run it up again.
4) Adjust the seater die plug until I have the proper seating.
My problem is that when I perform through step 3, there is not enough room in the seater die for me to screw the seater plug into it. If I put the seater plug in, it drives the bullet in so that the Overall length is 11.70 rather than 12.60, the measurement on a factory shell.
Any help is appreciated.

Screw the seater plug UP before doing step 3. Then screw it down to reach your desired OAL.

I just read this post four times and it just makes no sense. What press are you using and how many threads are on your dies? The description you give sounds right but just doesn't add up.

Here is what I do.

Put an empty case with bullet in the shell plate or holder.
Raise the ram by pushing the handle down
Turn the die down until you can feel the resistance.
Turn the seater plug in slowly until you can feel resistance.
Lower the ram by raising the handle.
Check to see if the bullet has gone down into the case.
Raise the ram again and turn the seater plug in a little at a time until you get the seating depth you want.
Back the seater plug out a quarter turn, and turn the die in slightly until you feel resistance again.
What you are doing is establishing the seater depth and then pushing up slightly on the brass to take the bell out of the mouth.
By doing this you will seat first, and then when the ram makes it to the top are "crimping" the mouth of the brass to hug the bullet.

Don't know if my phrasing is quite right, but I think you can see what I mean.
