Why not? Used correctly
Lee's collet neck die makes the neck id the same no matter the neck wall thickeness, that's their whole point of existing!
Would you care to estimate what percentge of reloaders you believe may have, or care about, tight neck chambers anyway? My bet would be less than .01%, (that would be less than one reloader in 10,000) so even if you were right it hardly matters when you should KNOW it doesn't apply to the OP or he would have said so.
