I did not record any speed, well my chronograph was all over the map, the lighting was non existent. Max book load was listed at 55.5grains, I had no pressure there but my brass was starting to lengthen a bit. ( fired brass headspace )
My medium node appears to be between 54.5-55.0 grains. OCW impacts had good relationship with each other and at 54.9 the group was 0.627". 55.2 had bad horizontal and 55.5 bad vertical. If i bump up above 55.5 I will hit the upper node but it may be too hot to live up there. ( easy bolt lift, no swipe, no happy face, primer was just barely flatter than my starting load.)
