I'm loading 50.2 grains of TAC in Lapua brass using Federal 210 GM primers topped off with 130 grain Barnes TTSX bullets. The rifle is a Winchester SS Model 70 Classic Featherweight. The velocity is 3,163 FPS and accuracy is under 1". The ammo is loaded .045" off touching the lands. I did not attempt to fine tune the rifle/load combination any further once I achieved the referenced accuracy and velocity. May do that in 2024 when components become more available.
