The scale Semi pointed me towards came today so I had to play with it. I took 100 of the last conicals I had cast with the Mountain Mold and weighed them. I put them in groups.
The lightest one I had was 496.8 and the heaviest one was 500.2
I was happy that they were pretty consistent.
The scale worked great. I went back and weighed some of the same bullets over and over and kept getting the same readings.
