When I used all my original Gamo Magnum pellets and needed more I went local and bought these because they were available. Simply put, these things just don't perform the same as the Gamo pellets. With the Gamo, it was one shot, one kill. With the Crosman, two and even three shots to do the job. It's wasteful and inhumane. Used both brands on woodchucks, rabbits, and squirrels. I use a Gamo Shadow 1000 if it makes any difference, but my recommendation is to take pass on the Crosman. It's time to order again and it's going to be Gamo.
