A big welcome to the GTA forum and family lbrooks. As you can see above....lot`s of different suggestions for pellets. From what I`ve read and experienced....almost all airguns have their own favourite pellet.....even if the airgun is the same brand, model and came off the assembly line one behind each other. You`ll have to try different brands/types of pellets to see which one your Whisper likes.
As someone have said....most "Package" scopes are pretty bad.....but sometimes even a bad one can last a long time. I had a "Package" CenterPoint and a Gamo Sporter that lasted over 2000 shots. And then I had a Bushnell Banner (Known to withstand the double recoil of airguns) that went bad after 700 shots. You never know with scopes.....but then, for sure most aftermarket scopes are more clear.
