I like both RL 15 and RL 19 with 120 grain Bullets, Rl 15 seems to have a slight edge in accuarcy and rl 19 seems to give a few more fps. This is in my Rem 700 LSS mountain rifle with 22 " barrel. your rifle may have different preferances. I also like Rl 19 with 125 grain partitions and N-560 with 140 grain partitions.
