The shoulder deal on the .375 -06 or its variants is a fantasy of people who drink and talk guns too much. The Hawk line has a 17.5 dg shoulder and it work fine up to .411. My only grip is that the angle isn't steep enough and I get stretching. To me the real pain is case forming from 35-06 brass. I will try 30-06 cylinderical brass for the next batch. Dave Schovill has an article in Rifle about working up the Hawk line. Find it; it is a great reference. The load data is in the Barnes manual's 3 &4.
I get 2825 with either 235 Speers or TSX's. in 90 deg. TX weather.
