180 grain Ballistic Silvertip with 84.5 grains of standard 7828 behind it loaded as long as your magazine box will take it. It was exceptionally accurate in my guns and the deer hated it. I think I killed around 180 whitetail with that load before I retired the rifle. Would have to go check the old books but it was in the 180-185 range and distances were from 10 yards to 675 yards. Used to shoot one of the rifles out to 1200 yards and it was a good shooter with that load. I tested about 30 different bullets in those guns and that is the one I settled on. Works well at those velocities that it can generate and it holds together. I never had one fail which is something I can't say about some of the other bullets. the old 180 Triple shock from Barnes is another really good one that had amazing accuracy.
