Bullet weight varied somewhat between 1020g and 1040g based on slight variations in the length of the copper cups. I will conduct some shooting tests to determine if a 2% variation in weight affects accuracy. I doubt that it will, but if it does, I'll sort the bullets by weight and use the high & lows for plinkers.

By streamlining this manufacturing process, and eliminating the machining and drilling of the cups, I was able to produce 25 bullets in 25 minutes. That's a savings of $225 per hour over the cost of the Woodleigh bullets. A very worth while project.


If they are acccurate as cast, my production rate rises to over 180 per hour. At that rate, I'll be able to stock-pile 400 bullets in a little over 2 hours.

Further testing has shown that accuracy was improved by annealing the copper cups prior to casting and pounding. Targets like this are very repeatable.
