Thank you. First I used stones primarily but I exchanged them with clay balls because as silly as it sounds good stones are hard to come by in my area. I found a source for nice iron cast balls, they're great because they are consistent in size and weight. After I broke some roof tiles on my shed I reconsidered and now I use tennis balls when in my backyard
, better for the integrity of my property, my neighbors health and the integrity of my neighbors property
. In the near future I get a mold for lead balls but I don't consider throwing them, it's just for having them in my assortment. I still have stones and iron balls around but when I'm on a walk I typically only throw clay balls now because they decay completely and are cheap.
As for the iron balls big ones 170g(0.37lbs) 35mm(0,138"), small ones 110g(0.24lbs) 30mm(0,118"), stones everything from 100g(0.22lbs) up to 200g(0.44lbs) and clay ball around 150g(0.33lbs). I hope I got the conversion right (trying to learn it
)
