.22 rim fire test Target

This is the target I cobbled together for the rim fire ammunition test.
I was thinking (hoping?) for four groups of five rounds each. This gives me four groups to average accuracy on, and a twenty round string for velocity numbers.

The only hitch I can think of is POA vs. POI. If the group centers more than an inch or two away from the point of aim, it might wander off the paper.
I guess we'll see!
