David and Goliath slingshot

[Paul]

Made myself out a a length of 4mm para-cord.
Cup is 2 inches diameter woven para-cord.
Straps 4 feet one with a thumb loop.
Neighbors? They don't care about me, I oblige back.

Finally hit the bucket, had to stop for a bit as my shoulder was hurting.
It's all in the spin I'm thinking. I've been using the shoulder to pick up speed. Don't.
Let the load do the work. only bit really moving is my wrist now.
Also, dropped the size of the shot. swopped onto modelling clay and the shot is about 3/4 the size of a golf ball.
Because there is less flaying round, the release is more controlled.
3 out of 10 shots on the bucket at 20 yards.
Getting better.
