50 X 68 Cal Aluminum Balls, Reusable Solid 68 Caliber Self Defense Balls Fit for Byrna SD/Salt Supply S2/ HDS/HDR 68, 7.3 Grams Kinetic Projectile Paintballs for Target Practice (BLK)

Can't go wrong with solid aluminum...

Great amo for salt s2launcher

Nice

Great product. Very effective. Heavier than the hard plastic projectile, so you have to be a little closer to target in order to get full effectiveness. But when it hits it will definitely do some damage.

Well-made even size they cycle through my TMC mag fed a little heavy but they do the job

I might feel bad for whatever gets in the way of these. But that’s what this is designed to do… can’t go wrong with metal if stopping an attacker is what you need to do at the moment

These'll hurt BIG TIME !!! -- You'll shoot your eye out, Ha-Ha

Fit perfectly in Byrna and work better than plastic/nylon
