OK, I found some wheel weights and cast 10# ww with a smallish peice of tin. I had the ww in ingots before trying this cast. Using a Lee 3565-125-2R molde, I am getting bullets with a .353" diameter. With the setup I was using the temp was a little on the cool side causing small wrinkles in most bullets. Would that also cause undersizing? Also these bullets were water dropped.
