I,ve been using RL23,RL17,Norma MRP,and RL26 in my
257 Roberts, it,s a Model 70 with a 24" barrel.
I Get Over 3100FPS With all these using the 110gr
Accubonds. I also get about the same Velocity with
the 115gr Nosler Partitions. In my rifle the
partitions are more accurate. I have a new box of
Barnes TTSX, so I,ll try the RL17 and the RL23
first.
