Which stage is crushing the shoulder?

1. no lube on the shoulder, just lube the case body during the full length resizing.
If you are crushing at this stage you need to examine your die and ensure that it is a Remington 223 die and base.

What reloading press are you using?

I forgot to mention that key point oops
I am crushing the shoulders on the seating step

Its a RCBS Rockchucker Supreme

First back the die insert all the way out.
Then run brass into the die, should be no change to the brass and no effort on the press
If the bullet is a flat base, you need to have belled the mouth of the brass
If the bullet is a boattail continue
put the bullet on the brass, the base of the bullet should be below the opening of the neck of the brass at least slightly
Put the brass/bullet up into the seating die
screw the seating tip into the die until it makes contact with the bullet
pull the round out of the die, measure length. If too long screw the seater in a bit further and run the round into the die again, then test length again.
Repeat until the desired overall length is acquired.

Sounds like you're trying to crimp the case during the bullet seating stage. Read the directions again, twice, taking note on how far to screw the die in when installing and when to use this die to crimp. Only time I had crushed casing was when I tried to crimp improperly.

It sounds like you are doing what I did on my first case. Your seating die is screwed in too far. You have to put the brass in and raise the ram all the way up then screw the die down till you feel it make contact with the case.

You're trying to crimp while you seat. You either set the die without a piece of brass, or with a piece of brass shorter than what you're loading with. As the bullet is still being slid into the case, the crimp is being applied. As you keep raising the ram the crimp gets so tight the bullet can't move, but the seating stem is still pushing down. Boom, crushed shoulders.
