The 158 WC & SWC is easier to score because of the nice clean holes they make, but I personally believe the 158 grain RNL is more accurate probably due to its shape not scratching off any lead in the forcing cone area. I switched from the WC & SWC to the RNL many years ago and have never looked back. For the informal target shooting I do these days, splitting hairs scoring is not an issue for me.
