Yea, all he had to do to get these velocity figures was to exceed the manufactures listed maxium load for a 165gr bullet by 2 grains! Alliant lists 50grs as their max load for 165gr bullet in the 308. MM got these velocities with 52grs! of RL-17.
Sorry but I don't think you can get there without loading to higher than normal pressures......................DJ
