2520 has given me the best velocities and most consistent performance. Velocities are significantly higher than any other powder -- faster or slower. Some say velocity doesn't mean anything and with most cartridges this is probably true. However with the Grendel you are already starting out at the low end of the performance spectrum so further losses in velocity equate to major problems given some winds or a requirement to estimate ranges -- both past 300.
