Bolo Rounds for Slingshots

i am a novice at slingshooting and like most novices i first started by shooting lead sinkers, however i have large number of sinkers that are not sphere in shape which prevents them for flying try and makes hard to practice so inspired the shot gun bolo round i have knocked some up miniture.

you will need
- pairs of sinkers, any size or shape
- gardening wire or snare wire
- scissors or pilers

all you need do is cut some wire and fold it back and twice it down, as long as you do this you can join as many sinkers together as you like to create a bigger round

result
I have used a piece of cardboard to show the impact patern off all three sinkers. This test is not perfect doesn't demonstrate the penetration but it demonstrates well that the bolo caused more damage then the sum of its parts. i would love to see what it does to balistic jell but.... i dont have none

i would also like hear any other ideas for uncoventional ammo you guys have
