Is the seating die contacting the shell holder? If it is, back it way out! It should only be turned in 1/2 turn (at most) after the crimp ring touches the top of a sized case.
Put a factory round in your shell holder. Back the seating die way out of the press. Back the seating stem way out of the die. Raise the ram to the top of its stroke and hold it there. Screw the seating die in until it sets firmly on the case and snug down the lock ring. Turn the seating stem down until it firmly contacts the bullet.
This will put you very close to being set with your rounds. If you have to move the seating die more that 1/2 turn from there something is wrong.
