Thank you for your answers. I pose the questions so we can have a discussion and provide information to anyone unfamiliar with bullet making. As you have noted some folks you know are swaging copper bullets for benchrest competition. I know someone that does this as well because he can make a better bullet then he can buy. The bullets he makes are uniformly concentric where bullet manufactures sell bullets with slight imperfections.
Because lead will strip out of the lands at high velocities for myself I figure copper bullets cast & swaged for rifles will be better performing than lead. Copper can be located nearly everywhere while lead can only be found in various collection centers.
