I want to start loading for my Marlin 30-30, and of course I would like to use cast boolits. I found the Oregon Trail 170gr gas-checked boolits on Midway and figured they would be a good place to start since I'm not set up to cast my own or put gas checks on. Does anyone know of a good source for load data for this boolit? I tried castpics but to no avail. I plan to use IMR 4198 or Reloader 7 if possible, since I have both on hand.
