Kit comes in two versions. One with thick and thin vegetable wads and a kit with vegetable wads and metal over shot wads. The metal over shot wad is more recoil resistant when your loading with shotloads and normal ammunition. Metal over shot wads are good when you load your cylinder with a few bullets for larger varmints. Recoil from the normal ammunition could dislodge shot loads with only vegetable wads. So, you can choose between the two over shot wads.
Each kit contains 50 powder wads and 50 over shot wads.
