ol' shooter gave you most of the explanation. there's a construction difference between a plated bullet and a jacketed bullet.
your bullet was cast to form and then chemically/electrically COATED with copper.
the true JHP's you have were formed by swaging a cup of jacket material around a cylindrical core.
the two types use different load data. use data for cast bullets with the plated hollowpoint.
