Does anyone happen to have book data for 223 loads using the Privi BTHP 75g or the barnes 62g TTSX and BL-c2 or Varget? I can't find any in my Hornady book or the Hogdon website. I know the 62gr copper is not a 1 for 1 swap with a lead bullet so the load data for lead 62gr would not apply here. Happy to buy a book if someone can point me toward a useful one.
