Speer's new No. 15 manual lists 57.8 grains of RL-26 as getting 2667 fps from a 24" barrel with the Hot-Cor 200-grain spitzer--which in general I have found gets just about the same velocity, with the same loads, as the 200 Partition.
Of course, test barrels are often a little tighter, both in bore and chamber throat, than factory barrels. And handloaders don't always load bullets to the same OAL, which also affects pressures and hence velocities.
Speer does not list the specific case, but for that load used the Federal 210 primer.
