I just got on the sporter barell 3050fps, with 0.5moa/100yards.
I got also very good grup 0.375 moa at 95gr Retumbo, but with hard extractor movement. So I stepped down to 91gr to be safer.
Now, I just rebarelled the rifle to a 338EDGE, and i'm in bullet development stage.
I tried US869 without good results, and now i'm using H-1000 with 92gr for 300SMK. The group is tighter, but I have to play with bullet deep seating. to tune the load.
