I have loaded them at 2.80 with H414 and at 2.765 with RL15. I've no idea of the exact source of this info, it is copied into my written notes, but I will have taken it from a printed manual. Hornady give a COL of 2.740 in their manual for the 23010 VMAX.
I've been loading them with RL15 recently, it is what I can get, and have found them pretty accurate. I found one book load that gave a max load of 47 grains of RL15 but I found that all loads below 47 grains, as I attempted to work up, gave me black cases and clear signs of low pressure. At 47 grains of RL15 I got my first clean case. I looked around other manuals that printed RL15 loads for such light bullets and found Speer were giving a 51 grain max. At 48.5 grains I got an accurate load and stopped there, with a COL of 2.765.
Hope that helps a little.
