My cheapest 9mm load is (all prices delivered) Bullets from S&S Casting 124 gr. Lead Round Nose $124.90 for 2,000, Unique Powder from Powder Valley 8 lbs $128.00, Wolf Primers from Widener's 5,000 for 125.00. I've never bought brass, it's all picked up at the range. Using 4.5 grains of Unique comes to: bullets $0.062 each, Powder $0.01 each and Primers $0.025 each for a total of $0.097 or $9.70 per 100. Leading has not been a problem in my M&P Pro. Happy loading! Bill
