There is no published Pro-2000MR data for the 8x57mm. These loads were extrapolated based off conversations with Alliant. For the 175 Sierra start at 50 grains and work up. My max for this bullet is set at 54 grains. There's more in the boiler room, however. For the 180 Nosler start at 49 grains and work up. My max for the 180 Nosler is set at 53 grains. I am currently working on an accurate 52.5 grain loading (2680 ft/sec), but need a couple more testing cycles in varying conditions. So far this is an outstanding powder for the 8x57mm. I am also continuing to work out 150 grain and 185 grain loads with Pro-2000MR for 2014.
