Things I liked: Sizing is consistent, no mold marks or injection point markings. Some disparity in accuracy between rounds as each has an air bubble in middle and is off to one side in many of them causing center of gravity to be off.
Things I would have changed: Nothing really, they are what they are.
What others should know: We had 15,000 of these, also 5,000 white, and 5,000 yellow, all from Crosman. These (red) were impossible to see in flight, good for stealth, bad for sighting in or just wanting to see where they are going. Also seem to be a more brittle plastic, these will crack or chip on hard surfaces. None of the white or yellow bb's did this. I suspect thee will breakdown with exposure to UV light outside, and eventually crumble (crude bio property).
