Found a good load recently for my 22" barreled Ruger M77 Hawekeye Predator. (These rifles have a mag box around 2.9"). It works well with Leupold's Long Range Duplex and B&C reticles, with the 300/400yd aiming points being "on" with a zero around 215yds.
150gr Nosler Accubond at 2.875" OAL
Lapua case
45.3gr H4895 (I bought a jug when Varget was Unobtanium)
CCI 200
2,875fps at 50 degrees Fahrenheit
The 150 Ballistic Tip shoots much the same, and to the same point of impact at 200/300/400yds, using the same seater setting, although OAL is a touch longer due to nose profile with my batch of bullets. The 150 E-tip made practically the same velocity, which is interesting, but did not shoot well enough for my tastes.
Hodgdon load data used 45.5gr with a W-W case for a 150 NBT, while I am using the thicker Lapua case, but I'm also using a longer OAL than their data. They made 2,870fps from a 24" barrel, so the data is fairly "real world".
