I just remove the mouth expansion on my 40S&W and it's good to go.

Is the crimping pressure causing the case to expand or belly out below the bullet?

Since it's 40S&W, have you carefully checked that the brass does not have a "belly" found in brass fired in pistols which have unsupported areas on the ramp. There’s a reason die makers sale “de-Glocking” fixer dies.
