On my 40 S&W rounds, I'm saving 60% consistently :
8lbs Unique = $100, which is one penny/round at 7 grain charge
10,000 Wolf small pistol primers = $210 delivered, so 2.1 cents/round
1000 Berry's bullets = $100 for the 155 grain, so 10 cents/bullet
This comes out to just over 13 cents/round. Compare that to about 30 cents/round for factory fodder. My reloads are far more accurate and more pleasant to shoot, as I download the powder charge for reduced recoil.
