Did the math to get a starting load to fireform, necked 10 cases, loaded up and down to the range

80gns 50BMG to start, can get about 5gns more in the pre fired case, will get about 10 max in the formed case.
At 80gns am getting 3050fps and sub 1/2 moa with the 130 Sierra HP Gameking, the HP Gameking normally goes 50-100 fps slower than other projectiles of the same weight in most calibres, and some power is being lost in blowing the case forward, looking forward to when the cases are done and the real development begins
