Description Videos Reviews Projectiles that erupt on contact! These projectiles are .68 caliber ammo filled with talcum powder that explode in a cloud of dust on impact. Are you a beginner? Use powderballs while you learn. If chalk is showing on your frame you know you've got a forkhit (but a forkhit that won't destroy your frame!). Are you pro? Use the powder balls as the target...such a satisfying explosion when hit! Sold in bulk bag - 500 powderballs per container. Review of Simple-Shots Powder Ball Ammo via YouTube Capture 3 Reviews 3 Powder Chalk Balls Posted by Kris on Mar 23rd 2018 Maybe it is my grip, but I am failing to see these really bust on impact. I have had some bust as soon as they leave the sling even though it doesn't show on the fork. Would also like to see a neon green powder like the advertisement shows. 5 Powder (chalk) Balls Posted by Ray on Mar 8th 2018 I love these!! As ammo or as targets they possess the nearly unique character when impact is made, produce a good puff of powder (what obviously looks like smoke). Very rewarding when shooting. One thing that I have noticed and is that when handling them they leave a waxy or greasy feel on the hand, right out of the packaging. No big deal. To mitigate this, I like to put powder in with them in a plastic shopping bag, thoroughly mix them around in the powder. Remove them from the powder and if I am ambitious roll them in an old towel to help further remove the powder and greasiness. I really enjoy putting them on top of a golf tee so that you know when you have a direct hit. No cheating bouncers if placed on pavement or concrete. 5 Wooooah! Posted by Slingshot Junkie on Feb 16th 2018 That is a big bag of FUN right there. I love these powderballs! These are the most fun projectile EVER and this is an amazing price. One thing: They don't explode as colorfully as the outer shell. The powder is pretty white.
