Review on SSR 100x Hard Rubber Balls: Paintballs for Self Defense Pistols & Training in 43 Cal (10.9 mm) by Marco Gavi

I've been under the impression since the addendum on the Rebolas that they are rubber coated steel balls and a description that led me to believe that was why I ordered them. This is not true as they are hard rubber, but they are harder than regular reusable rubber balls. I ran a rebound test and the Ram t4e's softer rubber balls bounce about an inch and these hard rubber balls fall off instantly and lie dead, but on longer hits they seem to stray a little more than my favorite nylon riding ball -Chucks. But still a bang for your buck. Might be a bit cheaper as there is no steel center but I agree with them when they play or shoot kids who don't listen lol.
