I shoot 180s Sierra game kings with 59.5 gr of hunter at 2860-2898 fps, Base to ogive 2.700. It’s a full house load. I might dial it down to 59gr.
I was on my last few rounds of the game kings, and have 200 of 180 Speer’s spritzer BT. I loaded them up same charge and same Base to give.
Forgot my tripod for the chronograph so I just flung some ammo down at 100 yards to see the difference.
I’m happy!

All of them do something better than the 30-06, but none of them do everything as well.
