Hodgdon's site lists the following data for the 158-gr Hornady XTP bullet with Winchester-231 powder. Is this close enough to try with the Winchester 158-gr JHP?
158 GR. HDY XTP 158 231 .357" 1.580" 6.2 1108 33,700 CUP 6.9 1220 40,000 CUP
Does anyone else load this bullet with either Winchester-231 or Vihtavuori-340 powders? If you feel like posting some data, that would be great!
