something vague

I am reloading .223 Remington for my Ruger M77 mark ii. I purchased a Lee Collet neck sizing die and after I went through my first sets of neck sized only rounds I feel as though the neck tension was a bit loose. Seating a bullet in my neck sized cases was much much easier feeling than seating a bullet in a F/L sized case from my RCBS die.
Finshed round with a bullet seated (Sierra 52gr. HPBT) outside neck diameter = .246" consistantly.
F/L sized case without a bullet seated outside neck diameter = .244" consitantly.
Lee Collet neck die without bullet seated outside neck diameter = .245" consitantly.
What is the proper size for outside diameter that I should be looking for before the bullet is seated? Is there enough bullet tension with the measurement I am getting with the Lee Collet die or do I need to sand the Mandrel down? And what are everyone's experience with Lee Collet dies? Do they seem to produce much runout, I don't have the means to measure this?
