    Does anyone have any experience using these in the Gamo Wildcat Whisper? If so, how to these rounds do? Thanks.

    • Johnny from USA answered:

      I use them in my Gamo Raptor and Gamo Rocket. They work great.

  • David from USA asked:

    Just went to an air gun range and they didnt let me use these pellets because it was lead. Is there any way to check what type of material the pellet is made of on this site?

    • Kara from USA answered:

      Im literally puking while reading your question. You must be going to the worst range on the face of the earth... or the universe.

    • Mark from USA answered:

      All pellet are lead except the Non-lead labeled products. They are tin-zinc alloy pellets.
