Things I liked: This is as close to a .22 cal bullet you will ever get with a air rifle pellet. They are accurate and they are destructive.
Things I would have changed: How about 50 more for the same price?
What others should know: They are heavy so you need to recalibrate your sight or scope just for them.
Things I liked: Large amount of surface area.
Things I would have changed: These are either in the wrong package or not manufactured properly. Their diameter is almost too large for even a snug fit in .22 caliber even when soaked with solvent. I had to pound them in with a rubber mallet. Then I was able to force them through with the cleaning rod.
What others should know: Can't see an advantage to these over typical cleaning cloth patches.
