buying in bulk means 15 lb kegs of powder, 50k primers or more at a time, 5,000 rds of brass, 10k cast bullets at a time (to get free shipping is VERY important with bullets). Check with places like Graf & Sons, in Mexico, MO. Look in the Shotgun News paper for bulk buys on oncefired brass and on "seconds" of the jacketed bullets. Better yet, practice with 9mm, carry 135 gr CorBon jhp's in your .40.
