Be very careful when using data from that source - or from any source which publishes load data from "individuals". You do not know if the loads are either safe or accurate. Only use data published by respected bullet makers, powder suppliers, or other sources (like Lyman) which actually TEST the published loads with pressure equipment.
Changing the bullet make, type and brand may - or may not - change the velocity and/or pressures of a particular load. For examp0le, if using Nosler bullets you should use Nosler data. If using Barnes X-bullets, you must use current Barnes data.
