When I first started reloading in 1973 the RN bullet was thought to have better "brush busting" capabilities. I actually took my first and biggest whitetail handload with a 180 gr. Hornady RN, it worked just fine. The buck field dressed 254# and went only 30 yds. after a front on chest shot. In recent years I have been loading spitzer bullets in my .257 Roberts and .35 Whelen. A 225gr. Sierra spitzer accounted for my most recent whitetail, a chest shot produced a complete pass thru with significant blood trail on both sides and a dead deer after going only 30 yds.. I would not be adverse to going back to RN bullets especially since most of my shooting opportunities are 100 yds. or less.
