Re: 300 RUM with 200gr MKS range results
Joel, at 91.2 gr, my ES = 8, my SD = 4 and the group at 100 was .3 center to center. I agree that I am slow, so I will probably load and chrono up to pressure signs. If my Chrono isn't lying, then I may end up above 95 gr in looking for the 3200 fps. I am not hung on it, accuracy over velocity in my book (within reason).
Joel you are shooting a 28" and Cinch is shooting a 27" barrel. With my 26" and Retumbo, I may be losing 30 fps per inch? That still should have me with 60 FPS or so of you and Cinch.
I have some 200gr AB's I can try. I will reload to my 91.2 and see if the groups stay and the velocity changes. I don't have any Federal 215M's , only CCI's, but, that is a sign of the times. I will work up the 200 gr AB's to pressure signs or to max velocity with accuracy.
