I've been working on some materials to use when educating people on airguns. Part of that is explaining that pellets come in multiple sizes, not just the .177cal. Also, trying to explain the difference in the speed and size of the pellets and how it impacts the penetration. I found a few good illustrations online that I thought I'd share if anyone is interested. I DID NOT create these and I don't own them. If someone else owns them and wants me to take them down please PM me.
