Warner Tool 361 gn on top of 134 gn of Retumbo, 3156 fps ,SD 6, .56 MOA. The keys turned out to be the Peterson brass and the Warner Tool custom die. Making rounds with near zero run out with really long bullets is hard, but an absolute requirement. The Autotrickler provides charges to a kernel, and I'm annealing after every firing. Poured a dram of the Talisker 25yo . Hope to get a new 2k video up soon
