Ok just got back from the range. This is out of my 28" Krieger #10 79 GR of h1000 behind a 208 GR Amax using CCI #200 Large rifle primer. Bullet seated .010 off the lands Velocities 2863, 2867, 2862 with one weird 2900 I think I had a powder grain under the plate of my dig scale and got a heavy charge in there? Using Horn brass fire formed in this chamber. Using a Lee neck sizer and measuring powder to the .1 grain. Got .7 MOA from a five shot group which strung up and down, the group measured .2 MOA from side to side. I think I have some issue with neck tension my case media leaves a powder residue inside the case. I am switching to plain corn cob media. I also plan to experiment with seating depth and Federal magnum primers and see what happens to the velocities and group sizes. But I am really happy with this.
