I recently finished my 338 edge build. It is a remington 700 action with 30 inch krieger 1-9.5 twist barrel. I have only tried 300 smk with RL25 . It will shoot very well but it is flattening primers bad with only 84.5 grains of powder. The velocity is around 2600-2650 with this load. It seems like this is pretty low compared to others. My oal is around 3.83. Trying to figure out how to get at least 2750-2850 out of it.
