Solid and aluminum

A little Loose fit for my HDB, rolled out the barrel. Wish it fit my HDB a little tighter.

I got these to use in my Byrna as practice rounds. The rubber ones I was using had such a bad bounce back in our back yard that I was worried I was going to hurt myself or someone else while practicing. These are solid and shoot straight. You can reuse them if your shooting into cardboard or some other non damaging impact surface but check them each carefully before doing so as you don't want to damage your gun with a misshapen or damaged ball. I think these would still do a lot of damage to a person if hit directly so use them responsibly. In my opinion they look cooler too!

I got these originally to put into monkey-ball keychains though figured I'd try them out in my slingshot just for fun. They work well and all feel uniform in size and weight. They're considerably lighter than steel shot but still pack a punch. I wouldn't want to be caught in front of them in any fashion. There is no doubt in my mind that these would hurt extremely bad if you got hit with them at any speed.

They fit very well in the Umarex T4E HDR68 marker but the finish is so rough that they fit almost too tightly causing a loss of velocity in your shots. If you look at the ball under magnification you will see tons of little fractures on the surface with sharp edges when you rub it. After you shoot a few you will see a bunch of flat spots where iit hit the hard target which means the aluminum is very soft and causes deformity to the surface so they are no longer round.It’s a good price but I was not satisfied with the quality and results.

Works well.
