I can not tell you if the RN is better than a SP but can say that the 154 Hornady RN at 7mm-08 velocities is devasting and as CLB said, as I am his hunting partner after shooting several deer with them, have not caught one yet. Besides that, at the ranges we hunt, this bullet is super accurate out of our guns. Stretch it out to 300 yds+, then go to a spitzer or bt spitzer.
