I got two boxes of old Rem 170gr Hollow Point core lok bullets (B22780) (.308) at a gun show. I'd like to use them with my Marlin 336 30-30 but I can't find any load data. I know better than to use data for Hornady or Speer bullets. Can I use data for the newer Rem 170gr core lok bullet? I thought I'd check with you guys.
