I shot 160 accubonds and H4831 for many years out of a sako 7 Rem mag. I recently built a 7 mag that I was going to shoot 140 bergers in and didn’t have any luck with how they shot. I tried some of my old accu bond reloads for my sako and got 3/4” groups. I never had any complaints with the 160 accubonds. I shot them at about 3025 fps.
