Be aware that Dust Devils do not always disappear in a nice puff smoke!
They can and do bounce back whole or in pieces.
They are high speed and accurate tho.
They are accurate and will raise your fps.
But they don't disintegrate.
Which makes them a bit pointless in my view.
Unless you like being showered by bits of bbs.
OK thanks everyone. I may investigate them in the interests of science.
I've tested DDs in a number of different CO2 powered airguns and they have turned to a fine powder upon impact. As with any target, it is important to be mindful of what you're shooting at and ensure all the usual precautions are taken. It's not impossible for the odd one to bounce but generally, they do what it says on the box. Certainly a lot safer than steel in my view.
