I need the specs for this old cartridge. I´m planning on reloading 125 grain cast lead RN´s or 158 grain cast LSWC´s with Alliant powders. What´s the correct diameter for this bullet: .358 or .360? I´ve read that the diameter will vary from one manufacturer´s barrel to another but I don´t know how or where to take the correct measurement. I tried getting the caliper between the grooves from the muzzle end but I don´t know if this is correct. Can anyone direct me to a websited with this info. Thanks in advance for the info!!!
