215 Berger Hybrid with 74grains of 2217 with Norma brass, getting 2870 FPS from a 26 inch barrel. I think I must have a fairly tight chamber as I started to get pressure signs about 1 grain below the Book max.
I found I got similar speeds with the 215 Hybrid and the 208 AMAX, apparently it has something to do with the short bearing surface.
I've only shot one animal with the Hybrid but it seemed to do the job, it left a pretty decent exit hole. (Tahr at around 600m)
