So I bought the Lee challenger kit a week back and love it, but I decided to verify the grain weight of the scale vs. a trued digital scale. With the Lee scale set at 49 grains the digital scale was showing 44.8. That's a huge difference! I decided to go back through the instructions for zeroing out the scale once again and retried. Again, the digital was showing about 4.5 grains less than the Lee. I went to my buddies and took the digital scale with me. We tried it against his RCBS scale. It was off by 1.8 to 2.5 grains. This would explain why my load data said I should be pushing 3200 fps but when I chrono'd my loads they were 2940 fps. I then used the digital to check bullet weights. It was dead on. The Hornady Vmax 75 grains all scaled out at 75.1 to 75.3. I think I'll stick to using a digital scale from now on. Anyone else have similar results?
