Just an FYI, Xtreme also offers a duplicate to the Berry's that there is a recipe for. The bullet by extreme is HPCBRN which is HP-for Heavy Plated, CB-for Concave Base and RN-for Round Nose and these are rated by Xtreme for velocities over 1200fps to 1500fps. They are only about $5 more per 500.
These HPCBRN shoot great for me using the recipes offered for the Berry's bullets of same design.
