Been testing on and off since last fall using water jugs to catch my boolits. My first try was using my 16 to 1 mix consisting of pure lead and pewter mix. It had a BH of 7.5. I tested this alloy with a Muzzel velocity at 1575fps. It made it into and stopped in the third small gatoraide bottle. (Updated)I just found the slug, weighed, and mesured it. I measured .645" and weighed 133 grains. I found another laying on the ground after my shooting session laying next to the bottles that weighed 110 grains. Both boolits looked the same accept for The overlapped pedal around the back of this boolit which accounted for the extra weight.
The next test was with. A 50/50 mix ACCOWW and pure adding 2% pewter to the mix. It had a BH of 10.5. I did not chrony the load yet but used 23.8gr of w296. I'm guessing it has to be between 1700-1800fps? It stopped in the 4th milk jug and weighed 124gr. It expanded to .780".
The last test I did today. Instead of milk jugs...because I didn't have any, I used totes filled with water. I tried four rounds into two totes I had lined up back to back. The totes were about 15 feet or so from my muzzle. I caught the first boolit and the front tote let loose at the same time and cracked so the other three rounds went completely through the first and second and into the ground. Needless to say I took a bath in the process. The alloy I tried today was a mix of 80/20 ACCOWW and pure. I added 12% pewter to the mix. It had a BH of 15.4. The boolit I recovered weighed 155 grains and had a diameter of .679". It made a nice looking mushroom.the boolit stopped in the opposite end of the tote and broke it on the opposite end and bounced back. Im guessing the tote it stopped in was as wide as 5 milk jugs, maybe more.
