| Does anyone have load data for 170gr Lead Flat points in .40 or a manual close by? I only have a few manuals and none list this weight. I will be using either Clays or Titegroup powder. I don't have any more info on the bullets I was given around 500 of them and after letting them age for 10 years I am finally going to load them. |

Lyman #49 lists a 175gr lead flat nose seated to 1.100" with a starting charge of 3.3 Clay's producing 641 fps, and a max charge of 4.0 Clay's producing 992 fps.
17,800 cup for the 3.3 charge, and 20,900 cup for the 4.0 charge. (Winchester WSP primer, case length .845") |

If it were me... I would use 180 grain lead data & work up from there. This. This + 2.... and check their diameter, coulda swore I read that, lead bullets will expand over longer periods of time.... I don't remember how much or how long it takes, but worth checking. |
