I used to use around 58 grains of IMR-4350 and a 165-grain bullet to test ’06s, but H-4350 does just as well. Muzzle velocity will be close to 2,900 fps.
With 180s around 59.0 grains of RL-19 provides a good combination of accuracy, with velocity pushing 2,800 fps in a 24-inch barrel.
For decades I used the 200-grain Nosler Partition and 59.0 grains of H-4831 as my heavy-game load in the ’06, for 2,600+ in 22-inch barrels.
If you like heavy bullets, this load shoots a lot flatter than you’d imagine.
