I am shooting the 300SMK in front of Retumbo. 93.5gr puts me right about 2800fps. I will be developing some loads with the 300 OTM soon.

99 grains of RL-33 gives me 2840 fps in a 26" barrel.

Riley,

What was your comparison MV with Retumbo? I didn't have much luck increasing MV changing to RL-33 over Retumbo in my LM.

Thanks
