Would it be safe to use the lower end of jacketed bullet data and then reduce that by 10% for a lead bullet? Or is it possible to take the overall weight of a bullet in grains and divide it by the lower end of the number of grains of powder and then multiply it by the number of grains you need? For example, 5.8/200=.029*300=8.7 5.8 is the lower end of number of grains of TiteGroup for a 200g lead bullet. .029 is the amount of grain of powder per grains of lead. I need data for a 300g lead bullet so I then multiplied .029*300 to get 8.7 grains of TiteGroup. Or 6.4/200=.032*300=9.6 using 231.
