I think that the consensus is that the nosler data is fairly weak ( which is the opposite of my usual experience with their data) for the grendel. In fact their max load is less than hogdons wth similar weight bullets. Also, the type of rifling can affect pressure and velocity. from what I have seen for data on this site and the grendel load books mid to upper 2400's is typical for 123 gr amax, sst with 8208 and 18" barrel.
