Welcome Justin.
Have you been slinging, or are you new to our sport?
Ballbearings are very heavy and thus potentially lethal, so not good beginners ammo.
But from what I read here they are really well liked by the people who can get them free or cheap.
And for a sling, the tape slings will handle them well too.
Medical tape is the best, but any tape will make a sling.
Click on the next line and you see how to make one.
