Ok, i have made a braided bolas using paracord, a marine grade steel ring and three round lead sinkers. two of the same weight 5oz and one of 3oz weight on a longer cord.
monkey fist all three then four plait round braid the whole lot.
It was a practice project for the braiding but it still should have worked as predicted.
Should the weights be the same?
should they be two light and one heavy? the reverse of what i have now.
Or do i suck and need more practice?
Or all different  weights.
I am building the reverse of what i have now for experimenting and will breakdown my first one should it need it.
Thought i would ask those who have gone before.

bolases are hard to throw - you probaby just need more practice

4 plait round braid with paracord? Trying using just one strand of normal paracord for each "arm". It should be plenty strong enough for bolas and it will wrap around the target much better.

Morphy,  it was my version of a rawhide one i saw on the net, it was also good practice, i like the sturdiness of it as it wont tangle before deployment, but i was having issues getting it to splay out.
As it stands i am going to deconstruct it and start again.

Bill is right…I've tried the "ring" method too and it didn't work too good.

And you have to get the right spin on release or they wont open up like helicopter blades. Takes a fair bit of practice.

What I do is hole one weight and rotate then release it so they are separated.
