Things I liked: Awesome penetration, lead free, look cool.
Things I would have changed: Offer a larger tin, they can be a bit inaccurate.
What others should know: These pellets are great. They have ridiculous penetration and are fairly accurate. I have a Gamo Shadow 640 (640 fps) and these will punch through just about anything you can put in front of them, even with the low power. The first day I got them I shot a spaypaint can. The pellet went right through the side of it, and the can took off like a rocket. It was amazing to see the power of these pellets, not to mention the fireworks that resulted after the can took off. This was really impressive because of the power of my gun. But they can be a little drifty. At 20 feet I shot a cluster of about 2 inches. This may also be due to the low power of my gun. Regardless of the drift, I love these pellets. They have incredible power and superb penetration. I would recomend these to anyone who wants a fun pellet.
Things I liked: These work great it my Cybergun Colt 1911Government gas gun.They are accurate, but I haven't used any other BBs so I don't really have aything to compare these to.
Things I would have changed: They are a bit expensive. Also you can't see these when you shoot them.
What others should know: There's no much to say here. The pellets are black so you (and the people you shoot) can't see them. They are on the expensive side, but I don't see anything wrong with them. They are all exactly the same, no defects in any BB I have seen. They are also supremely well polished. Good BBs, buy them.
