I do have this mold now, but bought a big tub of them at a gun shop that were obviously part of an estate. Cast pretty hard and the guy clearly knew how to cast so I took them home, checked and sized them, lube is Carnuba read and been playing with them in my '06 and .308 heavy bench guns.
Ben had written up a thread on it I read and the general wisdom by all is it's a good bullet, but you have to limit it to under 1600 FPS, no problem. Shot a variety of ten-shot groups in the rifle using load data from Lyman for Unique, 700X, Herco, etc., nothing special. Switched to 2400, same general velocity range and groups close up dramatically, not sure why this is, but it did it in both the '06 and more dramatically in the .308.
Seems strange a particular bullet would so strongly favor one powder like that. Anyone else shooting this bullet?
