I just set my all time record for the number of 9mm powder coated bullets cured in a single cook in my Hamilton Beach Countertop Toaster Oven. 621 bullets per rack times 4 racks = 2484 total. I made it happen by packing them in tight spaced with the help of a stainless wire cooling grate. My self closing tweezers were used to place the bullets, which is the fastest method I have found. The bullets were set the bullets on silicone cooking mats. The mats keep the bullets from sliding like they do on foil or parchment, so even an old man could walk 4 trays to the oven without toppling.
