I just took a CCI 38 shotshell out of the box and from what I can see looking through the blue capsule at appears the shot size is number 9. The box states that there are approx. 135 pellets per load.
If I remember correctly the 22s are loaded with shot size 12.
BTW: Snakes are a constant concern here while hiking around the desert. I usually carry a revolver with the first chamber loaded for snakes and the rest loaded for 2 legged vermin.
