Things I liked:The pellets fed and shot normally in several of my airsoft guns. The marking properties are minimal in my guns which all shoot under 400fps -- it may mark better in higher velocity guns. The overall rating is reduced because of this. Things I would have changed:These pellets leave a small amount of orange residue in my guns. Easy to brush out and I'm not sure this can be changed though. What others should know:As noted marking properties of the pellet are minimal. I was hoping there would be more on paper targets but there is just a trace of color.
