saves money practice shooting. I made a backdrop with a bed sheet stapled to a 2by4 to absorb the impact of the balls. The balls if dropped will bounce back up approx 2/3 of the original height so they BOUNCE. A blanket at the bottom of the sheet to keep them from bouncing and rolling is neccessary and I still found ones that rolled 30 feet. No lubeing required and they seem fairly indestructable and if not lost should last forever. The size is small, I measured @ .675 wheras my XBALL gold is .683. So shooting out of my .689 teardrop, they will roll through it. They accuracy is erratic, some are dead on, some curve- maybe a smaller barrel would improve them accuracy wise. It takes some time hunting them down when youre done as they bounce and roll. I bought 300 @actionvillage for $60 and think thats about the right amount as I can fill my hopper full and still lose a few here and there. Definately shoot in the house or enclosed space and not outside, although maybe a great trap might work
Shooting paint is quite pricy and messy and this allows you test fire, practice accuracy and has eliminated shooting 100's of balls at the Pb park to test the gun, for me. Doing an indoor match would work with them although the speed would have be turned down as they would hurt more to get hit with them.
