The only BBs I use now. These simply blow the competition away at 250 feet+ (paced off) and they hurt, but one kid still did not call his hits which makes me wonder how many welts I put on him, lol. But yes, these BBs are smooth, slick, and shiny all the way round the BB which means no cracks, no ejection marks nothin except white. They fly straight and true with about 1-2 fliers every 600 rounds or so.
This is true they don't come in a 5000 round bag. They are weighed by kilogram, so you get less .30 gram BBs than .20 or .25 BBs because more material is packed into the same diameter. Same amount of material per bag, more dense BBs, less BBs, more accuracy at range.
Best used with 400 fps and above, around 350 and under and the benefits are negligible compared with .25s.
Consistency in diameter 5.98 +- .02mm
Accurate at 400 fps
Price tag, but you get what you pay for.
Won't attract women
