Things I liked: Accurate, they actually expand, and consistent. I am shooting a Webley Vulcan MK1 and even for it being an old springer they are accurate. I have great hits with squirrels and soon rabbits. I have got to see the actual impact from them, and they do as advertised unlike lower end hollow points.
Things I would have changed: More per can, with a can that screws together.
What others should know: These are the perfect weight for spring and nitro piston rifles. If I was using a PCP I would consider a slightly heavier pellet.
