Were they "mostly" shot offhand, benchrest, or something else.
It looks like you are averaging about a tin a week. That's great!
I'm probably close to that although I stopped saving the empty cans. I actually had a bunch of gallon sized zip lock bags labeled with each of my Air Guns so I could tell how many rounds went through each one. One day I looked at them and said: why??? Now I just grab whatever AG I want and an open tin of JSB's. The empty cans actually make good, although very temporary, outdoor targets.
